The Brief Wondrous Life (and Long Dangerous Half-Life) of Strontium-90

Posted on by

Tooth to Science button2At roughly 5:30 in the morning on July 16, 1945, an implosion-design plutonium device, codenamed “the gadget,” exploded over the Jornada del Muerto desert in south-central New Mexico with a force equivalent to about 20,000 tons of TNT. It was the world’s first test of an atomic bomb, and as witnesses at base camp some ten miles away would soon relay to US President Harry Truman, the results were “satisfactory” and exceeded expectations. Within weeks, the United States would use a uranium bomb of a different design on the Japanese city of Hiroshima, and three days after that, a plutonium device similar to the gadget was dropped on Nagasaki, about 200 miles to the southwest.

Though Hiroshima and Nagasaki are the only instances where atomic weapons were used against a wartime enemy, between 1945 and 1963, the world experienced hundreds upon hundreds of nuclear weapons tests, the great majority of which were above ground or in the sea–in other words, in the atmosphere. The US tested atom and hydrogen bombs in Nevada, at the Nevada Test Site, and in the Pacific Ocean, on and around the Marshall Islands, in an area known as the Pacific Proving Grounds. After the Soviet Union developed its own atomic weapon in 1949, it carried out hundreds of similar explosions, primarily in Kazakhstan, and the UK performed more than 20 of its own atmospheric nuclear tests, mostly in Australia and the South Pacific, between 1952 and 1958.

Though military authorities and officials with the US Atomic Energy Commission initially downplayed the dispersal and dangers of fallout from these atmospheric tests, by the early 1950s, scientists in nuclear and non-nuclear countries alike began to raise concerns. Fallout from atmospheric tests was not contained simply to the blast radius or a region near the explosion, instead the products of fission and un-fissioned nuclear residue were essentially vaporized by the heat and carried up into the stratosphere, sweeping across the globe, and eventually returning to earth in precipitation. A host of radioactive isotopes contaminated land and surface water, entering the food chain through farms and dairies.

The tale of the teeth

In order to demonstrate that fallout was widespread and had worked its way into the population, a group of researchers, headed by Dr. Barry Commoner and Drs. Louise and Eric Reiss, founded the Baby Tooth Survey under the auspices of Washington University (where Commoner then taught) and the St. Louis Citizens’ Committee for Nuclear Information. The tooth survey sought to track strontium-90 (Sr-90), a radioactive isotope of the alkaline earth metal strontium, which occurs as a result–and only as a result–of nuclear fission. Sr-90 is structurally similar to calcium, and so, once in the body, works its way into bones and teeth.

While harvesting human bones was impractical, researchers realized that baby teeth should be readily available. Most strontium in baby teeth would transfer from mother to fetus during pregnancy, and so birth records would provide accurate data about where and when those teeth were formed. The tooth survey collected baby teeth, initially from the St. Louis area, eventually from around the globe, and analyzed them for strontium.

By the early ’60s, the program had collected well over a quarter-million teeth, and ultimately found that children in St. Louis in 1963 had 50 times more Sr-90 in them than children born in 1950. Armed with preliminary results from this survey and a petition signed by thousands of scientists worldwide, Dr. Commoner successfully lobbied President John F. Kennedy to negotiate and sign the Partial Test Ban Treaty, halting atmospheric nuclear tests by the US, UK and USSR. By the end of the decade, strontium-90 levels in newly collected baby teeth were substantially lower than the ’63 samples.

The initial survey, which ended in 1970, continues to have relevance today. Some 85,000 teeth not used in the original project were turned over to researchers at the Radiation and Public Health Project (RPHP) in 2001. The RPHP study, released in 2010, found that donors from the Baby Tooth Survey who had died of cancer before age 50 averaged over twice the Sr-90 in their samples compared with those who had lived past their 50th birthday.

But the perils of strontium-90–or, indeed, a host of radioactive isotopes that are strontium’s travel companions–did not cease with the ban on atmospheric nuclear tests. Many of the hazards of fallout could also be associated with the radiological pollution that is part-and-parcel of nuclear power generation. The controlled fission in a nuclear reactor produces all of the elements created in the uncontrolled fission of a nuclear explosion. This point was brought home by the RPHP work, when it found strontium-90 was 30- to 50-percent higher in baby teeth collected from children born in “nuclear counties,” (PDF) the roughly 40 percent of US counties situated within 100 miles of a nuclear power plant or weapons lab.

Similar baby teeth research has been conducted over the last 30 years in Denmark, Japan and Germany, with measurably similar results. While Sr-90 levels continued to decrease in babies born through the mid 1970s, as the use of nuclear power starts to spread worldwide, that trend flattens. Of particular note, a study conducted by the German section of the International Physicians for the Prevention of Nuclear War (winner of the 1985 Nobel Peace Prize) found ten-times more strontium-90 in the teeth of children born after the 1986 Chernobyl nuclear disaster when compared with samples from 1983.

While radioactive strontium itself can be linked to several diseases, including leukemia and bone cancers, Sr-90, as mentioned above, is but one of the most measurable of many dangerous isotopes released into the environment by the normal, everyday operation of nuclear reactors, even without the catastrophic discharges that come with accidents and meltdowns. Tritium, along with radioactive variants of iodine, cesium and xenon (to name just a few) can often be detected in elevated levels in areas around nuclear facilities.

Epidemiological studies have shown higher risks of breast and prostate cancers for those living in US nuclear counties. But while the Environmental Protection Agency collects sporadic data on the presence of radioactive isotopes such as Sr-90, the exact locations of the sampling sites are not part of the data made available to the general public. Further, while “unusual” venting of radioactive vapor or the dumping of contaminated water from a nuclear plant has to be reported to the Nuclear Regulatory Commission (and even then, it is the event that is reported, not the exact composition of the discharge), the radio-isotopes that are introduced into the environment by the typical operation of a reactor meet with far less scrutiny. In the absence of better EPA data and more stringent NRC oversight, studies like the Baby Tooth Survey and its contemporary brethren are central to the public understanding of the dangers posed by the nuclear power industry.

June and Sr-90: busting out all over

As if to underscore the point, strontium-90 served as the marker for troubling developments on both sides of the Pacific just this June.

In Japan, TEPCO–still the official operator of Fukushima Daiichi–revealed it had found Sr-90 in groundwater surrounding the crippled nuclear plant at “very high” levels. Between December 2012 and May 2013, levels of strontium-90 increased over 100-fold, to 1,000 becquerels per liter–33 times the Japanese limit for the radioactive isotope.

The samples were taken less than 100 feet from the coast. From that point, reports say, the water usually flows out to the Pacific Ocean.

Beyond the concerns raised by the affects of the strontium-90 (and the dangerously high amounts of tritium detected along with it) when the radioactive contamination enters the food chain, the rising levels of Sr-90 likely indicate other serious problems at Fukushima. Most obviously, there is now little doubt that TEPCO has failed to contain contaminated water leaking from the damaged reactor buildings–contrary to the narrative preferred by company officials.

But skyrocketing levels of strontium-90 could also suggest that the isotope is still being produced–that nuclear fission is still occurring in one or more of the damaged reactor cores. Or even, perhaps, outside the reactors, as the corium (the term for the molten, lava-like nuclear fuel after a meltdown) in as many as three units is believed to have melted through the steel reactor containment and possibly eroded the concrete floor, as well.

An ocean away, in Washington state, radiological waste, some of which dates back to the manufacture of those first atom bombs, sits in aging storage tanks at the Hanford Nuclear Reservation–and some of those tanks are leaking.

In truth, tanks at Hanford, considered by many the United States’ most contaminated nuclear site, have been leaking for some time. But the high-level radioactive waste in some of the old, single-wall tanks had been transferred to newer, double-walled storage, which was supposed to provide better containment. On June 20, however, the US Department of Energy reported that workers at Hanford detected radioactive contamination–specifically Sr-90–outside one of the double-walled tanks, possibly suggesting a breach. The predominant radionuclides in the 850,000-gallon tank are reported to be strontium-90 and cesium-137.

The tank, along with hundreds of others, sits about five miles from the Columbia River, water source for much of the region. Once contamination leaks from the tanks, it mixes with ground water, and, in time, should make its way to the river. “I view this as a crisis,” said Tom Carpenter, executive director of the watchdog group Hanford Challenge, “These tanks are not supposed to fail for 50 years.”

Destroyer of worlds

In a 1965 interview, J. Robert Oppenheimer, the Manhattan Project’s science director who was in charge of the Los Alamos facility that developed the first atomic bombs, looked back twenty years to that July New Mexico morning:

We knew the world would not be the same. A few people laughed, a few people cried. Most people were silent. I remembered the line from the Hindu scripture, the Bhagavad-Gita; Vishnu is trying to persuade the Prince that he should do his duty and, to impress him, takes on his multi-armed form and says, “Now I am become Death, the destroyer of worlds.” I suppose we all thought that, one way or another.

“We knew the world would not be the same.” Oppenheimer was most likely speaking figuratively, but, as it turns out, he also reported a literal truth. Before July 16, 1945, there was no strontium-90 or cesium-137 in the atmosphere–it simply did not exist in nature. But ever since that first atomic explosion, these anthropogenic radioactive isotopes have been part of earth’s every turn.

Strontium-90–like cesium-137 and a catalog of other hazardous byproducts of nuclear fission–takes a long time to decay. The detritus of past detonations and other nuclear disasters will be quite literally with us–in our water and soil, in our tissue and bone–for generations. These radioactive isotopes have already been linked to significant suffering, disease and death. Their danger was acknowledged by the United States when JFK signed the 1963 Test Ban Treaty. Now would be a good time to acknowledge the perspicacity of that president, phase out today’s largest contributors of atmospheric Sr-90, nuclear reactors, and let the sun set on this toxic metal’s life.

Fukushima Plus Two: Still the Beginning?

I was up working in what were in my part of the world the early morning hours of March 11, 2011, when I heard over the radio that a massive earthquake had struck northeastern Japan. I turned on the TV just in time to see the earliest pictures of the tsunami that followed what became known as the Tohoku quake. The devastation was instantly apparent, and reports of high numbers of casualties seemed inevitable, but it wasn’t until a few hours later, when news of the destruction and loss of power at the Fukushima Daiichi nuclear plant hit the English-language airwaves, that I was gripped by a real sense of despair.

I was far from a nuclear expert at the time, but I knew enough to know that without intact cooling systems, or the power to keep them running, and with the added threat of a containment breach, some amount of environmental contamination was certain, and the potential for something truly terrifying was high.

What started as a weekend of watching newswires and live streams, virtually around the clock, and posting basic tech and health questions on email lists, expanded as the Fukushima crisis itself grew. Two years later, I have written tens of thousands of words, and read hundreds of thousands more. I have learned much, but I think I have only scratched the surface.

We all might be a little closer to understanding what happened in those first days and weeks after the earthquake, but what has happened since is still, sadly, a story where much must be written. What the Daiichi plant workers really went through in those early days is just now coming to light, and the tales of intrigue and cover-up, of corruption and captured government, grow more complex and more sinister with each revelation. But what has happened to the environment, not just in the government-cordoned evacuation zone, but also throughout Japan, across the Pacific, and around the world, will likely prove the most chilling narrative.

Radiation levels in the quarantined parts of Japan are still far too high to permit any kind of human re-habitation, but exposure rates in areas far outside that radius are also well above what would have been considered acceptable before this disaster. And water, used to cool the molten cores and damaged spent fuel pools at Fukushima Daiichi, now dangerously radioactive itself, continues to leak into the ground and into the ocean at unprecedented rates.

Alas, the efforts of the Japanese government seem more focused on limiting the information, quieting dissent, and sharing the pain (by shipping radioactive detritus across the country for disposal and incineration), than it is on stopping the leaks, cleaning up the contamination, and eliminating future risks. Though originally pledged to quickly turn away from all nuclear power, a change of government in Japan has revived the incestuous relationship between the nuclear industry and the bureaucrats and politicians who are supposed to police it.

Across the Pacific, the United States has not exactly bathed itself in glory, either. Within days of the news of the explosions at Fukushima, President Barack Obama was the rare world leader that made a point of publicly assuring the nuclear industry that America’s commitment to this dangerous energy source was still strong. Just months after the start of the crisis, information on airborne radiation samples from across the country became less accessible to the public. And while industrialized countries like Germany work to phase out their nuclear plants, the US Nuclear Regulatory Commission actually approved construction of new reactors, and the federal government is poised to backstop the baldly risky investment to the tune of $8.3 billon.

But most disturbing of all, of course, will be the stories of the people. First, the stories we will hear from the families in Japan exposed to the toxic fallout in the immediate aftermath of the initial containment breaches and explosions–stories we are already hearing of children with severe thyroid abnormalities. But soon, and likely for decades to come, the stories of cancers and immune disorders, of birth defects and health challenges, elevated not only in northern Japan, but perhaps across the northern hemisphere.

Two years after the earthquake and tsunami, it is not the beginning of the end of this disaster, and, with apologies to Winston Churchill, it may not even be the end of the beginning. The spent fuel pool at Daiichi reactor 4 remains in precarious shape, and the state of the three molten cores is still shrouded in mystery. Radioactive dust and grime blanket large parts of Japan with no serious plan to remove it, and the waters off the northeast coast continue to absorb irradiated runoff, putting an entire aquatic food chain in peril.

On this second anniversary of the start of the Fukushima crisis, let us honor those who have suffered so far, review what we have learned to date, and endeavor to understand what is likely to come. But, most of all, let us renew our commitment to breaking with this dirty, dangerous and expensive technology.

To this end, on March 11 and 12, I will be attending a symposium at the New York Academy of Medicine, “The Medical and Ecological Consequences of the Fukushima Nuclear Accident,” sponsored by the Helen Caldicott Foundation and Physicians for Social Responsibility. If you are in the New York area, there is still space available; if you want to watch online, the organizers have promised a live stream.

New Fukushima Video Shows Disorganized Response, Organized Deception

Posted on by

A frame from early in the newly released Fukushima video.

Tokyo Electric Power Company (TEPCO), the operator of the Fukushima Daiichi nuclear power plant when the Tohoku earthquake and tsunami struck last year, bowed to public and government pressure this week, releasing 150 hours of video recorded during the first days of the Fukushima crisis. Even with some faces obscured and two-thirds of the audio missing, the tapes clearly show a nuclear infrastructure wholly unprepared for the disaster, and an industry and government wholly determined to downplay that disaster’s severity:

Though incomplete, the footage from a concrete bunker at the plant confirms what many had long suspected: that the Tokyo Electric Power Company, the plant’s operator, knew from the early hours of the crisis that multiple meltdowns were likely despite its repeated attempts in the weeks that followed to deny such a probability.

It also suggests that the government, during one of the bleakest moments, ordered the company not to share information with the public, or even local officials trying to decide if more people should evacuate.

Above all, the videos depict mayhem at the plant, a lack of preparedness so profound that too few buses were on hand to carry workers away in the event of an evacuation. They also paint a close-up portrait of the man at the center of the crisis, Mr. Yoshida, who galvanizes his team of engineers as they defy explosions and fires — and sometimes battle their own superiors.

That summary is from New York Times Tokyo-based reporter Hiroko Tabuchi. The story she tells is compelling and terrifying, and focuses on the apparent heroism of Masao Yoshida, Fukushima’s chief manager when the crisis began, along with the far less estimable behavior of TEPCO and Japanese government officials. It is worth a couple of your monthly quota of clicks to read all the way through.

The story is but one take on the video, and I point this out not because I question Tabuchi’s reporting on its content, much of which is consistent with what is already known about the unholy alliance between the nuclear industry and the Japanese government, and about what those parties did to serve their own interests at the expense of the Japanese people (and many others across the northern hemisphere). Instead, I bring this up because I do not myself speak Japanese, and I am only allowed to view a 90-minute “highlight reel” and not the entire 150 hours of video, and so I am dependent on other reporters’ interpretations. And because neither TEPCO nor the Japanese government (which now essentially owns TEPCO) has yet proven to be completely open or honest on matters nuclear, the subtle differences in those interpretations matter.

Tabuchi took to Twitter to say how much she wanted to tell the story as “a tribute to Fukushima Daiichi chief Yoshida and the brave men on the ground who tried to save us.” But in a separate tweet, Tabuchi said she was “heartbroken” to discover her article was cut in half.

Editing is, of course, part of journalism. Trimming happens to many stories in many papers. But I had to raise an eyebrow when I saw a note at the bottom of Tabuchi’s piece that said Matthew Wald “contributed reporting from Washington.” I have previously been critical of Wald–a Times veteran, contributor to their Green blog, and often their go-to reporter on nuclear power–for stories that sometimes read like brochures from the Nuclear Energy Institute. Wald tends to perpetuate myths in line with the old “clean, safe, and too cheap to meter” saw, while reserving a much, uh, healthier (?) skepticism for nuclear power critics and renewable energy advocates.

There is, of course, no way to know what Wald’s contributions (or redactions) were in this case, and it is doubtful any of the parties involved would tell us, but what particularly stokes my curiosity is this paragraph:

Despite the close-up view of the disaster, the videos — which also capture teleconferences with executives in Tokyo — leave many questions unresolved, in good part because only 50 of 150 hours include audio. The company blamed technical problems for the lack of audio.

TEPCO might blame technical problems, but reports from other news services seem to leave little doubt that the general belief is that the audio has been withheld–or in some cases most obviously obscured–by TEPCO. The BBC’s Mariko Oi saw it this way:

Tepco has bowed to pressure to release 150 hours of teleconferencing footage but the tape was heavily edited and mostly muted to “protect employees’ privacy”.

. . . .

Tepco is again under criticism for not releasing the full recordings and has been asked if it was removing more than employees’ names and phone numbers.

And Mari Yamaguchi of the Associated Press reported even more directly about TEPCO’s intent:

Japan’s former prime minister criticized the tsunami-hit nuclear plant’s operator Wednesday for heavily editing the limited video coverage it released of the disaster, including a portion in which his emotional speech to utility executives and workers was silenced.

Naoto Kan called for Tokyo Electric Power Co. to release all of its video coverage, beyond the first five days. Two-thirds of the 150 hours of videos it released Monday are without sound, including one segment showing Kan’s visit to the utility’s headquarters on March 15 last year, four days after a tsunami critically damaged three reactors at the Fukushima Dai-ichi power plant.

Many people’s faces, except for the plant chief and top executives in Tokyo, are obscured in the videos and frequent beeps mask voices and other sound.

The AP story also points out that the released video arbitrarily ends at midnight on March 15–and though it is not known how much more tape exists, it appears clear that TEPCO has held some substantial portion back. After five days, the Fukushima crisis was far from over, after all (as it is still far from over), and the recordings end amidst some of the disaster’s most critical events.

But the New York Times omits all of this, leaving TEPCO’s Rose Mary Woods-like excuse to stand as the innocent truth.

That’s a shame, because the way you read this story changes when you look at some of the horrific revelations keeping in mind that this is only the part TEPCO decided it could let you see. Here are just a few highlights. . . or lowlights:

  • Plant managers and TEPCO officials were aware from the earliest hours of the crisis that they were likely facing multiple meltdowns.
  • Japanese government officials withheld information–and ordered TEPCO to withhold information–on radiation levels that could have helped untold numbers of civilians reduce their exposure.
  • Despite warnings years prior that such natural disasters were possible in the region, Fukushima operators had no plan to deal with the damage and loss of power caused by the quake and tsunami.
  • TEPCO did not even have the infrastructure or procedures in place to evacuate its own employees from an imperiled facility.
  • Plant officials were–from the earliest days–as worried about the spent fuel pools as they were about the reactors. Those on the scene feared that most of the pools at Daiichi, not just the one at reactor four, were facing loss of coolant and the fires and massive radiation leaks that would follow, though publicly they said none of the pools were a danger at the time.

And there is more about the dire conditions for plant workers, the lack of food or water, the high levels of radiation exposure, and even a point where employees had to pool their cash to buy water and gasoline. And, as noted above, that’s just the part TEPCO has deemed acceptable for release.

Above all, though–beyond the discrepancies in reporting, beyond the moral failings of TEPCO and government officials, beyond the heroism of those at the crippled facility–what the new Fukushima tapes reveal is what those who watch the nuclear industry have mostly known all along. Nuclear power is dangerous–the radiation, the complexity of the system, the waste, the reliance on everything going right, and the corrupt conspiracy between industry and government saddle this form of energy production with unacceptable risks. The video now available might shed some light on how things at Fukushima went horribly wrong, but the entire world already knows plenty of who, what, where and when. We all know that things at Fukushima did go horribly wrong, and so many know that they must suffer because of it.

Made in Japan? Fukushima Crisis Is Nuclear, Not Cultural

Posted on by

Since the release of the Fukushima Nuclear Accident Independent Committee’s official report last week, much has been made of how it implicates Japanese culture as one of the root causes of the crisis. The committee’s chairman, Dr. Kiyoshi Kurokawa, makes the accusation quite plainly in the opening paragraphs of the executive summary [PDF]:

What must be admitted – very painfully – is that this was a disaster “Made in Japan.” Its fundamental causes are to be found in the ingrained conventions of Japanese culture: our reflexive obedience; our reluctance to question authority; our devotion to ‘sticking with the program’; our groupism; and our insularity.

That this apparently critical self-examination was seized upon by much of the western media’s coverage of the report probably does not come as a surprise–especially when you consider that this revelation falls within the first 300 words of an 88-page document. Cultural stereotypes and incomplete reads are hardly new to establishment reportage. What might come as a shock, however, is that this painful admission is only made in the English-language version of the document, and only in the chairman’s introduction is the “made in Japan” conclusion drawn so specifically.

What replaces the cultural critique in the Japanese edition and in the body of the English summary is a ringing indictment of the cozy relationship between the Japanese nuclear industry and the government agencies that were supposed to regulate it. This “regulatory capture,” as the report details, is certainly central to the committee’s findings and crucial to understanding how the Fukushima disaster is a manmade catastrophe, but it is not unique to the culture of Japan.

Indeed, observers of the United States will recognize this lax regulatory construct as part-and-parcel of problems that threaten the safety and health of its citizenry, be it in the nuclear sector, the energy sector as a whole, or across a wide variety of officially regulated industries.

No protection

The Japanese Diet’s Fukushima report includes a healthy dose of displeasure with the close ties between government regulators and the nuclear industry they were supposed to monitor. The closed, insular nature of nuclear oversight that might be attributed to Japanese culture by a superficial read is, in fact, a product of the universally familiar “revolving door” that sees industry insiders taking turns as government bureaucrats, and regulatory staff “graduating” to well-compensated positions in the private sector.

Mariko Oi, a reporter at the BBC’s Tokyo bureau, described the situation this way when discussing the Fukushima report on the World Service:

When there was a whistleblower, the first call that the government or the ministry made was to TEPCO, saying, “Hey, you’ve got a whistleblower,” instead of “Hey, you’ve got a problem at the nuclear reactor.”

A disturbing betrayal of accountability in any context, it is especially troubling with the ominous repercussions of the Fukushima disaster still metastasizing. And it is also ominously familiar.

Look, for example, just across the Pacific:

[San Onofre Nuclear Generating Station] was chastised two years ago by the U.S. Nuclear Regulatory Commission for creating an atmosphere in which employees fear retaliation if they report safety concerns.

. . . .

Edward Bussey, a former health physics technician at the plant, sued Edison in state court after he was fired in 2006 under what he said were trumped-up charges that he had falsified initials on logs documenting that certain materials had been checked for radiation. Bussey contended that he was really fired in retaliation for complaining about safety concerns to his supervisors and the NRC.

San Onofre–SONGS, if you will–has been offline since January when a radioactive steam leak led to the discovery of severely degraded copper tubing in both of the plant’s existing reactors. But here’s the real kicker: whistleblower suits at SONGS, like the one from Mr. Bussey, have routinely been summarily dismissed thanks to a little known legal loophole:

San Onofre is majority owned and operated by Southern California Edison, a private company, but it sits on land leased from the Camp Pendleton Marine Corps base.

That puts the plant in a so-called federal enclave, where courts have held that many California laws, including labor laws intended to protect whistle-blowers, do not apply.

Lawsuits filed in state court by San Onofre workers who claimed that they were fired or retaliated against for reporting safety concerns, sexual harassment and other issues have been tossed out because of the plant’s location.

The Los Angeles Times cites examples dating back to the construction of San Onofre where personnel who complained about safety or work conditions were terminated and left without many of the legal options normally afforded most California citizens. The history of SONGS is liberally peppered with accidents and safety breaches–and the lies and cover-ups from its owner-operators that go with them. Considering that San Onofre employees are regularly punished for exposing problems and have fewer whistleblower protections, is it at all surprising that SONGS is reported to have the worst safety record of all US nuclear plants?

If San Onofre’s track record isn’t evidence enough of the dangers of weak regulation, the findings and conclusions of the latest Fukushima report make it crystal clear: “safety culture” is not undermined by Japanese culture so much as it is by the more international culture of corruption born of the incestuous relationship between industry and regulators.

It’s a nuclear thing…

But the corrupt culture–be it national or universal–is itself a bit of a dodge. As noted by the Financial Times, the Japanese and their regulatory structure have managed to operate the technologically complex Shinkansen bullet trains since 1964 without a single derailment or fatal collision.

As the Diet’s report makes abundantly clear–far more clear than any talk about Japanese culture–the multiple failures at and around Fukushima Daiichi were directly related to the design of the reactors and to fatal flaws inherent in nuclear power generation.

Return for a moment to something discussed here last summer, The Light Water Paradox: “In order to safely generate a steady stream of electricity, a light water reactor needs a steady stream of electricity.” As previously noted, this is not some perpetual motion riddle–all but one of Japan’s commercial nuclear reactors and every operating reactor in the United States is of a design that requires water to be actively pumped though the reactor containment in order to keep the radioactive fuel cool enough to prevent a string of catastrophes, from hydrogen explosions and cladding fires, to core meltdowns and melt-throughs.

Most of the multiple calamities to befall Fukushima Daiichi have their roots in the paradox. As many have observed and the latest Japanese report reiterates, the Tohoku earthquake caused breaches in reactor containment and cooling structures, and damaged all of Fukushima’s electrical systems, save the diesel backup generators, which were in turn taken out by the tsunami that followed the quake. Meeting the demands of the paradox–circulating coolant in a contained system–was severely compromised after the quake, and was rendered completely impossible after the tsunami. Given Japan’s seismic history, and the need of any light water reactor for massive amounts of water, Fukushima wouldn’t really have been a surprise even if scientists hadn’t been telling plant operators and Japanese regulators about these very problems for the last two decades.

Back at San Onofre, US regulators disclosed Thursday that the damage to the metal tubes that circulate radioactive water between the reactor and the steam turbines (in other words, part of the system that takes heat away from the core) was far more extensive than had previously been disclosed by plant operators:

[Each of San Onofre’s steam generators has] 9,727 U-shaped tubes inside, each three-quarters of an inch in diameter.

The alloy tubes represent a critical safety barrier — if one breaks, there is the potential that radioactivity could escape into the atmosphere. Also, serious leaks can drain protective cooling water from a reactor.

Gradual wear is common in such tubing, but the rate of erosion at San Onofre startled officials since the equipment is relatively new. The generators were replaced in a $670 million overhaul and began operating in April 2010 in Unit 2 and February 2011 in Unit 3.

Tubes have to be taken out of service if 35 percent — roughly a third — of the wall wears away, and each of the four generators at the plant is designed to operate with a maximum of 778 retired tubes.

In one troubled generator in Unit 3, 420 tubes have been retired. The records show another 197 tubes in that generator have between 20 percent and 34 percent wear, meaning they are close to reaching the point when they would be at risk of breaking.

More than 500 others in that generator have between 10 percent and 19 percent wear in the tube wall.

“The new data reveal that there are thousands of damaged tubes in both Units 2 and 3, raising serious questions whether either unit should ever be restarted,” said Daniel Hirsch, a lecturer on nuclear policy at the University of California, Santa Cruz, who is a critic of the industry. “The problem is vastly larger than has been disclosed to date.”

And if anything, the Nuclear Regulatory Commission is underplaying the problem. A report from Fairewinds Associates, also released this week, unfavorably compared San Onofre’s situation with similar problems at other facilities:

[SONGS] has plugged 3.7 times as many steam generator tubes than the combined total of the entire number of plugged replacement steam generator tubes at all the other nuclear power plants in the US.

The report also explains that eight of the tubes failed a “pressure test” at San Onofre, while the same test at other facilities had never triggered any more than one tube breach. Fairewinds goes on to note that both units at San Onofre are equally precarious, and that neither can be restarted with any real promise of safe operation.

And while the rapid degeneration of the tubing might be peculiar to San Onofre, the dangers inherent in a system that requires constant power for constant cooling–lest a long list of possible problems triggers a toxic crisis–are evident across the entire US nuclear fleet. Cracked containment buildings, coolant leaks, transformer fires, power outages, and a vast catalogue of human errors fill the NRC’s event reports practically every month of every year for the past 40 years. To put it simply, with nuclear power, too much can go wrong when everything has to go right.

And this is to say nothing of the dangers that come with nuclear waste storage. Like with the reactors, the spent fuel pools that dot the grounds of almost every nuclear plant in America and Japan require a consistent and constantly circulating water supply to keep them from overheating (which would result in many of the same disastrous outcomes seen with damaged reactors). At Fukushima, one of the spent fuel pools is, at any given point, as much of a concern as the severely damaged reactor cores.

Ions and tigers and bears, oh my!

Even with the latest findings, however, Japanese Prime Minister Yoshihiko Noda pushed ahead with the restart of the precariously situated and similarly flawed nuclear reactor complex at Oi. It is as if the PM and the nuclear industry feared Japan surviving another summer without nuclear-generated electricity would demonstrate once and for all that the country had no reason to trade so much of its health and safety for an unnecessary return.

But the people of Japan seem to see it differently. Tens of thousands have turned out to demonstrate against their nation’s slide back into this dangerous culture of corruption. (Remember, the Oi restart comes without any safety upgrades made in response to the Fukushima disaster.)

And maybe there’s where cultural distinctions can be drawn. In Japan, the citizenry–especially women–are not demonstrating “reflexive obedience,” instead, they are demonstrating. In the United States, where 23 nuclear reactors are of the same design as Fukushima Daiichi, and 184 million people within 50 miles of a nuclear power plant, when the chairman of the Nuclear Regulatory Commission suggested requiring some modest upgrades as a response to the Fukushima disaster, the nuclear industry got its henchmen on the NRC and in Congress to push him out. . . with little public outcry.

Still, the BBC’s Mariko Oi lamented on the day the Fukushima report was released that Japanese media was paying more attention to the birth of a giant panda at a Tokyo zoo. That sort of response would seem all too familiar to any consumer of American media.

That baby panda, it should be noted, has since died. The radioactive fallout from Fukushima, however, lingers, and the crisis at Daiichi is far from over. The threat to global heath and safety that is unique to nuclear power lives on.

Frontline’s Fukushima “Meltdown” Perpetuates Industry Lie That Tsunami, Not Quake, Started Nuclear Crisis

Posted on by

In all fairness, “Inside Japan’s Nuclear Meltdown,” the Frontline documentary that debuted on US public television stations last night (February 28), sets out to accomplish an almost impossible task: explain what has happened inside and around Japan’s Fukushima Daiichi nuclear facility since a massive earthquake and tsunami crippled reactors and safety systems on March 11, 2011–and do so in 53 minutes. The filmmakers had several challenges, not the least of which is that the Fukushima meltdowns are not a closed case, but an ever-evolving crisis. Add to that the technical nature of the information, the global impact of the disaster, the still-extant dangers in and around the crippled plant, the contentious politics around nuclear issues, and the refusal of the Tokyo Electric Power Company (TEPCO) to let its employees talk either to reporters or independent investigative bodies, and it quickly becomes apparent that Frontline had a lot to tackle in order to practice good journalism.

But if the first rule of reporting is anything like medicine–“do no harm”–than Frontline’s Fukushima coverage is again guilty of malpractice. While “Inside Japan’s Nuclear Meltdown” is not the naked apologia for the nuclear industry that Frontline’s January offering, “Nuclear Aftershocks,” was, some of the errors and oversights of this week’s episode are just as injurious to the truth.

And none more so than the inherent contradiction that aired in the first minutes of Tuesday’s show.

“Inside'” opens on “March 11, 2011 – Day 1.” Over shaking weather camera shots of Fukushima’s four exhaust towers, the narrator explains:

The earthquake that shook the Fukushima Dai-ichi nuclear power plant was the most powerful to strike Japan since records began. The company that operates the plant, TEPCO, has forbidden its workers from speaking publicly about what followed.

But one year on, they are starting to tell their stories. Some have asked for their identities to be hidden for fear of being fired.

One such employee (called “Ono” in the transcript) speaks through an interpreter: “I saw all the pipes fixed to the wall shifting and ripping off.”

Then the power went out, but as Frontline’s narrator explains:

The workers stayed calm because they knew Japanese power plants are designed to withstand earthquakes. The reactors automatically shut down within seconds. But the high radioactivity of nuclear fuel rods means they generate intense heat even after a shutdown. So backup generators kicked in to power the cooling systems and stop the fuel rods from melting.

Frontline then tells of the massive tsunami that hit Fukushima about 49 minutes after the earthquake:

The biggest of the waves was more than 40 feet high and traveling at over 100 miles an hour.

. . . .

At 3:35 PM, the biggest of the waves struck. It was more than twice the height of the plant’s seawall.

. . . .

Most of the backup diesel generators needed to power the cooling systems were located in basements. They were destroyed by the tsunami waters, meaning the workers had no way of keeping the nuclear fuel from melting.

The impression left for viewers is that while the quake knocked out Fukushima’s primary power, the diesel backup generators were effectively cooling the reactors until the tsunami flooded the generators.

It’s a good story, as stories go, and one that TEPCO and their nuclear industry brethren are fond of telling to anyone and everyone within the sound of their profit-enhanced, lobbyist-aided voices. They have told it so often that it seems to be part of the whole Fukushima narrative that less-interested parties can recount without so much as glancing at their talking points. Indeed, even Frontline’s writers thought they could toss it out there without any debate and then move on. One problem with that story, though–it’s not true.

I personally saw pipes that had come apart and I assume that there were many more that had been broken throughout the plant. There’s no doubt that the earthquake did a lot of damage inside the plant… I also saw that part of the wall of the turbine building for reactor one had come away. That crack might have affected the reactor.

Those are the words of a Fukushima maintenance worker who requested anonymity when he told his story to reporters for Great Britain’s Independent last August. That worker recalled hissing, leaking pipes in the immediate aftermath of the quake.

Another TEPCO employee, a Fukushima technician, also spoke to the Independent:

It felt like the earthquake hit in two waves, the first impact was so intense you could see the building shaking, the pipes buckling, and within minutes I saw pipes bursting. Some fell off the wall…

Someone yelled that we all needed to evacuate. But I was severely alarmed because as I was leaving I was told and I could see that several pipes had cracked open, including what I believe were cold water supply pipes. That would mean that coolant couldn’t get to the reactor core. If you can’t sufficiently get the coolant to the core, it melts down. You don’t have to have to be a nuclear scientist to figure that out.

Workers also describe seeing cracks and holes in reactor one’s containment building soon after the earthquake, and it has been reported that a radiation alarm went off a mile away from Fukushima Daiichi at 3:29 PM JST–43 minutes after the quake, but 6 minutes before the tsunami hit the plant’s seawall.

Indeed, much of the data available, as well as the behavior of Fukushima personnel, makes the case that something was going horribly wrong before the tsunami flooded the backup generators:

Mitsuhiko Tanaka, a former nuclear plant designer, describes what occurred on 11 March as a loss-of-coolant accident. “The data that Tepco has made public shows a huge loss of coolant within the first few hours of the earthquake. It can’t be accounted for by the loss of electrical power. There was already so much damage to the cooling system that a meltdown was inevitable long before the tsunami came.”

He says the released data shows that at 2.52pm, just after the quake, the emergency circulation equipment of both the A and B systems automatically started up. “This only happens when there is a loss of coolant.” Between 3.04 and 3.11pm, the water sprayer inside the containment vessel was turned on. Mr Tanaka says that it is an emergency measure only done when other cooling systems have failed. By the time the tsunami arrived and knocked out all the electrical systems, at about 3.37pm, the plant was already on its way to melting down.

In fact, these conclusions were actually corroborated by data buried in a TEPCO briefing last May–and they were of course corroborated by “Ono” in the opening minutes of Frontline’s report–but rather than use their documentary and their tremendous access to eyewitnesses as a way of starting a discussion about what really went wrong at Fukushima Daiichi, Frontline instead moved to end the debate by repeating the industry line as a kind of shorthand gospel.

This is not nitpicking. The implications of this point–the debate about whether the nuclear reactor, its cooling systems and containment (to say nothing yet of its spent fuel pools and their safety systems) were seriously damaged by the earthquake–are broad and have far-reaching consequences for nuclear facilities all over the globe.

To put it mildly, the pipes at Fukushima were a mess. Over the decade prior to the Tohoku quake, TEPCO was told repeatedly about the poor state of the plant’s pipes, ducts, and couplings. Fukushima was sighted numerous times for deteriorating joints, faked inspections and shoddy repairs. Technicians talk of how the systems didn’t match the blueprints, and that pipes had to be bent to match up and then welded together.

Fukushima was remarkably old, but it is not remarkable. Plants across Japan are of the same generations-old design. So are many nuclear reactors here in the United States. If the safety systems of a nuclear reactor can be dangerously compromised by seismic activity alone, then all of Japan’s reactors–and a dozen or more across the US–are one good shake away from a Fukushima-like catastrophe. And that means that those plants need to be shut down for extensive repairs and retrofits–if not decommissioned permanently.

The stakes for the nuclear industry are obviously very high. You can see how they would still be working overtime to drown out the evidence and push the “freak one-two punch” narrative. But it’s not the true story–indeed, it is dangerous lie–so it is hard to reconcile why the esteemed and resourceful journalists at Frontline would want to tell it.

* * *

That was not the only problem with Tuesday’s episode, but it is one of the most pernicious–and it presents itself so obviously right at the start of “Inside Japan’s Nuclear Meltdown.” Also problematic was the general impression left at the end of the program. While mention is made of the 100,000 displaced by the 12-mile Fukushima exclusion zone, nothing is said about the broader health implications for the entre country–and indeed for the rest of the world as radioactive isotopes from Fukushima spread well beyond Japan’s borders.

Alas, though Frontline tells of the massive amounts of seawater pumped into the damaged facility, nothing much is said about the contaminated water that is leaving the area, spreading into groundwater, rivers and the Pacific Ocean. The show talks of the efforts to open a valve to relieve pressure inside one reactor, but does not address growing evidence that the lid of the containment vessel likely lifted off at some point between the tsunami and the explosion in building one. And there is a short discussion of bringing the now-melted-down reactors to “cold shutdown,” but there is no mention of the recent “re-criticality“–the rising temperatures inside one of the damaged cores.

And to that point–and to a point often made in these columns–this disaster is not over. “Japan’s Meltdown” is not in the past–it is still a dangerous and evolving crisis. The “devil’s chain reaction” that could have required the evacuation of Tokyo is still very much a possibility should another earthquake jolt the region. . . which itself is considered likely.

Sadly–disturbingly–Frontline’s Fukushima tick-tock ends leaving the opposite impression. They acknowledge the years of work that lie ahead to clean up the mess, but the implication is that the path is clear. They acknowledge the tragedy, but treat it as does one of the film’s subjects, who is shown at Frontline’s end at a memorial for his lost family–it is something to be mourned, commemorated and honored.

But Fukushima’s crisis is not buried and gone, and though radioactive water has been swept out to sea and radioactive fallout has been blown around the world, the real danger of Fukushima Daiichi and nuclear plants worldwide is not gone with the wind.

As noted above, it is a difficult task to accurately and effectively tell this sweeping story in less than an hour–but the filmmakers should have acknowledged that and either refocused their one show, or committed to telling the story over a longer period of time. Choosing instead to use the frame of the nuclear industry and the governments that seek its largess is not good journalism because it has the potential to do much harm.

New Fukushima Report: “Devil’s Chain Reaction” Could Wipe Out Tokyo

Posted on by

Map of the east coast of Japan showing the distance between Tokyo and Fukushima Daiichi, 150 miles to the north.

A new independent report on the Fukushima Daiichi Nuclear disaster reveals that Japan’s Prime Minister Naoto Kan feared events following the March 11, 2011 Tohoku earthquake and tsunami would require the evacuation of Tokyo. The report, conducted by the Rebuild Japan Foundation, a new policy organization comprised of college professors, journalists and lawyers, sheds new light on just how in-the-dark many were in the wake of natural disasters that left the Fukushima nuclear facility with damaged safety systems and without internal or external power.

The investigation underscores the conflicting interests of the Japanese government, the directors of Tokyo Electric Power Company (TEPCO–Fukushima’s owner and operator), and those on the scene at the crippled nuclear plant. Masataka Shimizu, president of TEPCO, is said to have ordered all of Fukushima Daiichi’s employees to evacuate the facility in the days after March 11, but Daiichi’s plant manager, Massao Yoshida, argued that he could get the damaged reactors under control if he and nuclear workers remained. PM Kan eventually ordered a skeleton crew to stay at the plant, fearing that Fukushima Daiichi, the nearby Fukushima Daini and a third nuclear facility could spiral out of control and start what has been translated as a “devil’s chain reaction” or a “demonic chain reaction” that would necessitate evacuation of the nation’s capital, a city of 13 million people, 150 miles south of Fukushima prefecture.

Given this new window on internal deliberations (far too nice a word–these were likely frantic, heated arguments) in Japan, the decision made by US Nuclear Regulatory Commission Chairman Gregory Jaczko within days of the quake to recommend evacuating American citizens from an area 50 miles around Fukushima seems downright conservative. In recent days, nuclear power proponents have used this action as their latest volley in their ongoing push to oust Jaczko and replace him with a more servile chief regulator.

Interesting, too, the objections of TEPCO’s president to the plan to pour seawater on the melting Fukushima reactors and boiling spent fuel storage pools. This last-gasp measure, apparently the idea of Yoshida, the Daiichi manager, is believed to have somewhat cooled the reactors and at least kept the fuel pools from completely emptying–which would have resulted in a much more serious outcome (hard to believe, but true)–though it should be noted that the radioactive runoff is now contaminating the ground, groundwater, rivers and the ocean around Fukushima. TEPCO brass no doubt did not want to use seawater because its corrosive effects would make it impossible to ever restart any of the Daiichi reactors (again, ridiculous in hindsight, but not hard to imagine inside the profit-above-people distortion bubble that exists at companies like TEPCO). (UPDATE: Japan Times reports Kan was reticent to use anything but fresh water, but Yoshida ignored him and went ahead with the use of seawater.)

Other recent revelations–about how close Fukushima Daini came to a meltdown of its own, about how the Fukushima region is now more seismically unstable, and that the government had dire assessments of the disaster that it worked hard to keep secret–serve to buttress Naoto Kan’s fears that a string of nuclear disasters was a distinct possibility. And it should also serve as a warning that those fears are still a possibility if the region’s nuclear plants–whether or not they are still functioning–are not decommissioned and contained.

And all this information, and the new details on the lack of trust between the Japanese government and TEPCO, also paints a more nuanced–and, honestly, disturbing–picture of the environment in which US officials had to make decisions.

But, perhaps most importantly, this latest report is yet another data point against the absurd assertion that Fukushima Daiichi somehow proves nuclear power’s “defense in depth” safety systems work. The assertion that Fukushima isn’t a massive disaster, just as it stands today, is ridiculous, but reading about the lack of good information in the early days of the crisis, the internal fights and the government’s fears makes it clear that things could have easily been much, much worse. While there are still real concerns about just how much radiation residents throughout Japan will be expected to absorb, and there are still many technical questions that remain unanswered, it now appears that it was only a combination of an occasionally assertive PM, the heroism of about fifty Daiichi workers and maybe some dumb luck that gave the world the relative luxury of calling Fukushima an ever-metastasizing disaster, rather than an almost-instant hell on earth.

You Could Even Say It Glows: NRC Votes to Fast-Track a More Dangerous Nuclear Future

Posted on by

To paraphrase the United States Nuclear Regulatory Commission, Merry Effin’ Christmas.

In a news dump that came a day early (because who really wants to dump on Christmas-Eve Eve?), the Nuclear Regulatory Commission made a pair of moves Thursday that could have significant consequences for America’s nuclear industry–and all the people who have to live with it.

First, the Westinghouse AP1000 reactor design got the big thumbs up:

The Nuclear Regulatory Commission unanimously approved a radical new reactor design on Thursday, clearing away a major obstacle for two utilities to begin construction on projects in South Carolina and Georgia.

Whoa–let’s stop it there for a sec. . . . A “radical new reactor design?” Somebody’s being a good little scribe this Christmas. As previously discussed, there is nothing radical about the AP1000–it’s a tweak on the generations-old pressurized water reactor design that theoretically would allow the core to avoid a meltdown in the event of a total loss of AC power. . . .

Well, for 72 hours, anyway.

After that, the manufacturer–in reality the Japanese owner of Westinghouse, Toshiba–says something about it taking only “minimal operator effort” to avert disaster.

Keep in mind that the AP1000 was designed well before the Japanese earthquake and tsunami that started the ongoing Fukushima disaster, but this approval, of course, comes well after.

Designers of the AP1000 assert that gravity and convection will serve to keep reactor cooling functioning even if systems are disabled as they were at Fukushima. That assertion is predicated on the storyline that the Daiichi plant’s safety systems survived the massive quake, and only ran into trouble when the tsunami flooded and disabled the diesel backup generators that powered cooling systems for the reactors and the spent fuel pools.

That is a capricious assertion for two very disturbing reasons:

First, it is by no means established fact that Fukushima’s cooling systems survived the earthquake undamaged. Reports from the Japanese government and TEPCO, Fukushima Daiichi’s owner-operator, have gone back and forth on this matter. It would be naturally beneficial to nuclear advocates to go with the story that the quake did nothing to the reactor and its safety systems. But given the visible damage to the plant and the surrounding area, and given the profound leaking of cooling water that has continued seemingly unabated from the earliest days of the disaster, it is hard to believe all pipes, tubes, couplings, fittings, vents and valves–not to mention the containment vessels and tanks themselves–remained watertight after the massive temblor.

Second, the earthquake worthiness of the AP1000, itself, has been officially questioned by senior NRC officials and Rep. Ed Markey (D-MA), the Ranking Member of the House committee charged with overseeing nuclear regulation:

Just days before the earthquake in Japan, Rep. Markey wrote a letter to the NRC urging the Commission not to approve the Westinghouse AP1000 design until serious safety concerns were addressed. One of NRC’s longest-serving staff, Dr. John Ma, had warned in NRC documents that the reactor’s containment could shatter “like a glass cup” due to flaws in the design of the shield building if impacted by an earthquake or commercial aircraft. The shield building has the critical safety function of preventing damage to the reactor that could cause fuel meltdowns and radiation releases.

Note, Dr. Ma has been with the NRC since its inception, and this was the first non-concurrence dissent of his career. The NRC acknowledged this concern and asked Westinghouse for a response. . . and the response was, essentially, “nah-ah.” A response that has now proven good enough for the agency tasked with assuring the safety of America’s nuclear reactors.

So, it theoretically would be great if the AP1000 were able to survive without melting down through three days without electrical power–though it should be noted that three days wouldn’t have really saved Fukushima’s bacon (even if it had remained intact) given the devastation to the region’s infrastructure. But that semi-sunny selling point on the AP1000 assumes that there would still be a reactor containment building to cool.

It is the kind of “what could possibly go wrong” assumption that has tripped up nuclear power generation in large and small ways throughout its history–and it is stunning that, especially in the wake of the Japanese crisis, this cavalier attitude continues.

But perhaps it is not so surprising when we consider just why the AP1000 has such a novel/brittle containment building: it is supposedly cheaper to build.

The AP1000 is slated to have a smaller footprint with fewer components, but still use off-the-shelf, previous-generation parts. Most notably, the design uses under a fifth the amount of concrete and rebar, compared with existing PWRs.

Not convinced that economics is the real driving force behind this “innovation?” Take a look at the other action the NRC announced Thursday:

In an unusual step, the commission waived the usual 30-day waiting period before its approval becomes official, so its decision will be effective in about a week. That moves the utilities closer to the point where they can start pouring concrete for safety-related parts of the plant.

The decision also moves the industry toward the first test of a streamlined procedure in which the commission will issue a combined construction and operating license. Up to now reactors had to obtain a construction license and then undergo a long wait for an operating license, resulting in expensive delays in starting up reactors that had essentially been completed.

The approval of a shaky design is disturbing, but the approval of a process that will allow that design to move to completion and operation with far fewer pauses to test safety is unconscionable. (And the fact that this happening because of bottom-line concerns is criminal.) As the distinguished gentleman from Massachusetts put it:

“Today, the NRC has presented its holiday gifts to the nuclear industry,” said Rep. Markey, top Democrat on the House Natural Resources Committee and a senior member of the House Energy and Commerce Committee. “Instead of doing all they should to protect nuclear reactors against seismically-induced ground acceleration, these Commissioners voted to approve the acceleration of reactor construction. While they continue to slow walk the implementation of recommendations of the NRC professional staff’s Near-Term Task Force on Fukushima, they have fast-tracked construction of a reactor whose shield building could ‘shatter like a glass cup’ if impacted by an earthquake or other natural or man-made impact.”

And it is important to mention that the approval of this accelerated process came over the objections of NRC Chairman Gregory Jaczko–who just last week faced both House and Senate panels questioning his leadership style–but the certification of the AP1000 design did not. In fact, at the same time news of the Jaczko witch hunt was blocking out the sun, the NRC chair was actually working with other commissioners–the ones who sent a letter to the White House saying Jaczko was impossible to work with–to secure the unanimous OK for the new reactor.

It is not the first time those wary of a nuclear renaissance had been presented with the dilemma of both praising and cursing Jaczko. In fact, just last week, on December 15, Jaczko was the only vote in support of a move to make all recommendations of the post-Fukushima Near-Term Task Force report mandatory for the “adequate protection” of nuclear power plants. The four other NRC commissioners asserted that it was “premature” to make such a rule–and so Fukushima’s lessons continue to go unlearned, over Jaczko’s protestations and lonely protest vote.

But it is just this sort of nightmare-inducing nuclear mollycoddling that should convince Jaczko that the process he has often praised is deeply flawed. He cannot advocate for new safety rules one week and then grant license to the industry that works so hard against those rules the next. Not if he really wants change; not if he really cares about public safety.

The Party Line – August 26, 2011: Virginia Quake Yet Another Wakeup Call for Sleepy Nuclear Regulators (Plus: Japan’s PM Resigns)

Posted on by

Late Thursday, Sen. Dianne Feinstein (D-CA) made this observation over at The Huffington Post:

Uninterrupted electricity is essential for nuclear safety. Without electricity, nuclear power plants are unable to pump cooling water through reactor cores and spent fuel pools to prevent overheating and fuel melting.

Without power, plant operators cannot control reactor activity or remotely monitor spent fuel.

It was the loss of electrical power that led to the partial-meltdown of multiple reactors, significant radiation release and damage to the spent fuel pools at the Fukushima Daiichi plant in Japan after the devastating 9.0 earthquake and tsunami in March.

First, I can’t move on without noting two problems there in the last paragraph.

I don’t know how Feinstein defines it, but I think most of the world has dropped the “partial” from the assessment of the meltdowns at Japan’s Fukushima Daiichi nuclear facility. Maybe DiFi has some secret pictures that show tiny bits of intact cladding floating on top of the blobs of corium now understood to be at the bottom of at least some of the damaged reactors, and so she feels uncomfortable going all the way, but the company that nominally runs the facility and the country that is unlucky enough to serve as its home feel sure enough to call it a meltdown without the modifier, so I think US Senators should, too.

Also, it is now believed that a meltdown in at least one of the reactors started before the tsunami that followed Japan’s March 11 earthquake. In other words, as I reported previously, the earthquake damaged the containment vessel or, more likely, the cooling system before the massive wave knocked out the backup generators and, thus, power to the cooling system. So, the loss of power did not lead to at least some of the meltdown—earthquake damage did.

That is not just an academic nitpick, it goes directly to how Feinstein and the entire US regulatory structure should evaluate the safety of domestic nuclear power plants.

Second: “Uninterrupted electricity is essential for nuclear safety.” Just think about that for a second. Uninterrupted electricity is essential for the safe generation of electricity. It is a logic that seems as vulnerable to reason as nuclear cooling systems are to seismic and tidal events.

But third, I do want to congratulate Senator Feinstein for recognizing and writing the obvious:

The incident [Tuesday’s magnitude 5.8 quake centered in Virginia] was a stark reminder of how vulnerable America’s nuclear power plants are to natural disasters.

I mean that congratulations sincerely. Yes, we didn’t really need a new reminder—Japan’s Fukushima disaster is recent and ongoing—but the Mineral, VA earthquake was another indication that our nuclear plants are vulnerable to natural and manmade disasters at many points. And more American politicians should say just what DiFi said, instead of brushing off Japan’s already extant stark reminder as a “can’t happen here” event, or quickly forgetting Tuesday’s quake because it resulted in “minimal damage and no loss of life” (to use Feinstein’s own rosy words).

Feinstein continues by laying out four “lessons” that Japan and Virginia should teach us. (It is really more like two or three points with repeats, but that’s OK.) The headlines:

First, our country needs a comprehensive, national policy to address the management of spent fuel, the radioactive waste produced while generating electricity by fission.

Second, today’s efforts to protect against seismic and flooding hazards may not be sufficient.

Third, we must improve the redundant safety systems to respond to disasters.

Finally, for spent fuel stored at reactor sites, dry casks are safer and more secure than permanent storage in spent fuel pools.

Both the first and fourth points note that storing spent fuel in pools of circulating water is not a particularly safe, efficient, or cost-effective way of dealing with one of nuclear power generation’s biggest problems. Not only are these pools also dependent on an uninterrupted source of electricity to keep water circulating and levels high enough to keep the rods—now packed in at many times the pools’ original designed capacity—from overheating and melting themselves or cracking the water and triggering hydrogen explosions, the cooling systems for the pools are also vulnerable to seismic events.

Feinstein says that spent rods should be moved to dry casks and eventually to a secure repository, observing that spent fuel in Japan housed in dry casks had no problems after the March 11 quake and flood. Strangely, though, the senator cites the Nuclear Regulatory Commission’s special taskforce report on the aftermath of the Japanese disaster as the inspiration for making this call for dry casks and a national fuel repository—strange because, as both Physicians for Social Responsibility and I noted back when the report was released, the task force pointedly did not make any recommendations for moving spent fuel to dry casks or to off-site repositories.

Feinstein also says she has learned that protections against earthquakes and flooding may not be sufficient. Again, DiFi modifies—there is really no need to say “may” here. From Fukushima Daiichi to the reactors in Virginia known as North Anna 1 and 2, it should now be very clear that nuclear plants are walking a precarious line between “minimal damage” and catastrophic failure.

Let’s look more closely at what happened on Tuesday. A 5.8 earthquake centered 15 miles from the North Anna nuclear power generating facility cut electrical power to the plant. Backup diesel generators kicked in to provide power to the cooling systems, averting the overheating of either the reactor core or the pools of spent fuel. Good news, as far as it goes, but there are several disconcerting caveats.

First, we don’t know if the plant—which is theoretically designed to withstand a quake of a 6.2 magnitude—has actually emerged from Tuesday’s tremor completely unscathed. The reactors are currently being brought to a cold shutdown so that they may be inspected further. Not only must the containment vessels be more closely inspected, the cooling system must be tested for leaks. Some of the pipes and conduits for that system are underground. As reactor expert Paul Gunter has noted, an underground rupture, one that might be leaking radioactive tritium into ground water, is quite possible and needs to be investigated more fully.

(As a caveat to the caveat, I must note that we also need to find a way to verify that the public is being fully informed about any damage and radioactive leaks—not a sure thing in light of both the evolving story of cover-up in Japan and this summer’s expose on collusion between the NRC and the nuclear industry.)

Second, the North Anna plant gets its name from Lake Anna, an artificial lake created to provide a reservoir for the cooling requirements of the nuclear facility. What if the quake had caused the dam that holds the water in Lake Anna to rupture? Beyond the dangerous flooding to well-populated communities downstream, the water level in the reservoir would drop to a point where the nuclear plant’s cooling system would fail. If this were to happen, no amount of redundant power generation would fix the problem. Does this sound farfetched? It is not. Virginia is noteworthy for its lack of attention to its aging infrastructure—in fact, according to the American Society of Civil Engineers’ infrastructure report card [PDF], the condition of Virginia’s dams gets a D-minus.

(It should be noted that the initial inspection of the Lake Anna dam after Tuesday’s quake showed no new damage.)

Third, not all of North Anna’s backup generators worked on Tuesday. Only three of the four came online after power was lost. (Hooray for required redundancy.) What is not clear is what effect this had on the plant’s ability to function normally, or what would have happened if grid power had not been restored as quickly to the facility.

Fourth, there is emerging evidence that seismic activity can increase as the result of the pressure from dammed reservoirs, as well as from hydraulic fracturing (which has been going on in the vicinity of Tuesday’s epicenter).

And finally, to simply give a Richter scale number as a sort of assurance of the safety of a nuclear facility is overly simplistic if not downright deceptive. Here’s why:

As noted here today and before, there are many systems that have to survive an earthquake—the reactor containment vessel, its cooling system, the spent fuel pools, their cooling systems, the reactor building, the monitoring equipment, and a plant’s connection to a steady supply of electrical power. In theory, all these systems were evaluated when the plans for a nuclear facility were initially approved. They all should survive a quake of a specified magnitude.

However, all of America’s nuclear facilities were licensed during a time when regulators assessed designs based on what is called Deterministic Seismic Hazard Analysis (DSHA). But, as noted in a May Congressional Research Service report [PDF]:

Since then, Probabilistic Seismic Hazard Analysis (PSHA) has been adopted as a more comprehensive approach in engineering practice. Consequently, the NRC is reassessing the probability of seismic core damage at existing plants.

I am not an expert in plate tectonics, but what I read tells me that you would feel more secure with a PSHA-generated standard—and what I have learned from Fukushima is that I want that standard applied to all the systems needed to safely operate a nuclear power plant. But what this report tells me is that the NRC is only in the midst of some process of reevaluating plants’ seismic vulnerability—a process that was to have begun last year but has moved very slowly (and this is only the evaluation stage)—and that this re-evaluation is of the probability of core damage, which, to my eye, is not the same as an evaluation of every system needed for the reactor and the spent fuel pools to remain safe.

And I am not alone in my worries. Here’s the NRC itself after it looked at North Anna in April (via the Institute for Southern Studies and the Center for Public Integrity):

Specifically, the NRC report notes that portions of water and gaseous suppression systems and hose stations “are not seismically designed.”

The report noted that “potential leakage can occur through penetrations following seismic event.”

And with specific regard to the spent fuel pools, ISS continues:

There’s also concern about what a major quake would mean for the water-filled pools used to store spent fuel at most U.S. nuclear plants. Bob Alvarez, a senior scholar at the Institute for Policy Studies who recently authored a report on the dangers of spent fuel storage in the United States, addressed the issue in a piece on the IPS blog posted shortly after the quake:

The North Anna reactors are of the Westinghouse Pressurized Water design and went on line in 1979 and 1980 respectively. Since then the reactors have generated approximately 1,200 metric tons of nuclear spent fuel containing about 228,000 curies of highly radioactive materials — among the largest concentrations of radioactivity in the United States.

Alvarez went on to note that almost 40 percent of the radioactivity in North Anna’s spent fuel pools is in the form of cesium-137, a long-lived isotope that presents serious health risks and accumulates in the food chain. He continued:

The spent fuel pools at North Anna contain four to five times more spent fuel than their original designs intended. As in Japan, all U.S. nuclear power plant spent fuel pools do not have steel lined, concrete barriers that cover reactor vessels to prevent the escape of radioactivity. They are not required to have back-up generators to keep used fuel rods cool, if offsite power is lost. Even though they contain these very large amounts of radioactivity, spent reactor fuel pools in the United States are mostly contained in ordinary industrial structures designed to protect them against the elements.

This goes to explaining the confusion I see over whether just parts or the entirety of a nuclear facility is required to meet a specific earthquake safety standard. But what it doesn’t do is imply that a single, plant-wide standard will be used in the future.

As noted when the special task force report came out earlier this summer, the recommendation that the current patchwork of safety rules should be unified and standardized was actually being slow-walked by three of the five NRC commissioners. Finally, one week ago, the commission agreed to give its technical team 45 days to analyze some of the recommendations, but they will be given a full 18 months to analyze the recommendation that the NRC revise its entire regulatory framework in light of lessons learned after the Fukushima disaster.

It should also be noted that there is currently no law that requires the NRC to apply the new, better seismic standards when evaluating requests for license renewals or the building of additional reactors at existing facilities. (There is a bill, languishing in the House, designed to fix this. . . did I mention it was languishing?)

Which brings us back to Senator Feinstein, or, really, her California colleague, Sen. Barbara Boxer (D), who chairs the Committee on Environment and Public Works and has oversight responsibilities over the NRC. While DiFi has written about the lessons of this week’s Virginia quake, Boxer has demanded action on the NRC taskforce report on the lessons learned from Fukushima. At a hearing on August 2, Boxer demanded the NRC pick up the pace on evaluating the recommendations and report back to her by November. With the NRC’s decision on how it will move forward, and the latest in a lengthening string of “wakeup calls” having caused incidents at North Anna and a number of other eastern nuclear facilities, perhaps both of California’s Senators might consider official hearings before then.

It must also be mentioned that while I was writing this post, Japan’s Prime Minister, Naoto Kan, has stepped down. Stories on the resignation concurrently cite his dismal poll numbers from an anti-nuke electorate, and the lack of support from pro-nuclear members of his party. Kan, who had previously hinted at leaving after the Fukushima crisis was brought under control (it seems I correctly predicted he’d be gone well before that), has also signaled that he wanted to wean Japan off nuclear power for electrical generation and move more aggressively toward renewable sources. Both possible reasons for his early exit speak to some form of accountability—one to the public, the other to entrenched nuclear industry masters—and both have probably played some roll. But what matters going forward is to whom the next leader will answer, and what happens with Japanese nuclear facilities will make that very clear.

In the US, we have a less clear choice—no one has proposed a move away from nuclear power (quite the contrary)—which, alas, probably tells us who calls the shots in our country. But that ugly political reality doesn’t change the physical one—United States nuclear facilities remain vulnerable to numerous seismic and tidal threats. As Diane Feinstein concludes, “We need to learn the lessons we can to assure that next time we are ready—not just lucky.”

The Party Line – July 22, 2011: Fixing a Hole

Posted on by

Focusing on broad, long-term goals while ignoring obvious, near-term problems is order of the day, be it in the Fukushima reactors or deficit-obsessed DC.

I feel like I am saying this every week, but tear yourself away for a minute, if you can, from the daily deficit follies—I promise we’ll get back to them.

As I detailed last week, a study called the Near-Term Task Force Review listed a set of suggestions for ways the US nuclear power industry could improve safety in the wake of the meltdowns and continuing crisis in Japan’s Fukushima reactors. The recommendations were a mixed bag of mostly regulatory tweaks–nothing particularly bad, as far as they go–but obviously missing from the report was any program that would effectively improve the way spent fuel rods are stored.

Earlier this week, the task force officially presented its report to the Nuclear Regulatory Commission, and NRC chair Gregory Jaczko said the full commission should move to accept or reject the recommendations within 90 days, and implement any new rules within five years.

That sounds glacial, especially given the ongoing Japanese crisis and many US plants of similar design facing the possibility of similar problems, but even this cautious approach to some cautious recommendations was more-or-less opposed by three of the five commissioners.

The commissioners reacted much like the Republican leadership on the House Energy and Commerce Committee did a day earlier, asking for a “full and deliberate process of review”—a rather naked demand that the NRC slow-walk these recommendations with an eye toward weakening or killing them. The ECC has yet to schedule any hearings on the task force report.

On the Senate side, I am told that the Committee on Environment and Public Works will hold hearings in August, but nothing as yet is listed on the committee website. (EPW is chaired by Barbara Boxer; if you want, give her a call and express your interest in a timely hearing.)

Sadly, it seems like the US takeaway from the triple meltdown and massive environmental disaster in Japan is that we need to stick up for our domestic nuclear industry. In fact, just yesterday, the NRC approved a 20-year operating license extension for Hope Creek in New Jersey. Hope Creek is a boiling water reactor, just like Fukushima Daiichi 1, and stores spent fuel in above-ground pools, just as was done in the now-crippled Japanese plants.

Conveniently, practically no one in the US has any time to devote to nuclear concerns—after all, we are facing a debt-pocalypse!

I write that with a healthy degree of sarcasm, but it seems to me more than a happy accident that absolutely nothing else can get done in Washington because of the never-healing, self-inflicted wound that has tied our governing in knots and threatens to cripple the entire government. Forgive the cheap allusion, but it is a meltdown of accountability.

An easy turn of phrase, but I have been feeling like there is some deeper connection—or, if not connection, parallel—between the ongoing crisis in Fukushima and the never-ending “crisis” in Washington.

Earlier in the week, TEPCO (the power company that owns Fukushima Daiichi) and the Japanese government updated their plans for cleanup and containment of the disaster area. They announced that their goal is a cold shutdown of the crippled reactors in three to six months, and with that, they hope to reduce the radiation level around the plant to one millisievert per year by mid-January. That would be substantial. Officials even talk of allowing some to return to the quarantine area if that goal is met.

But for that goal to be met—for any of the goals to be met, really—the crews at Fukushima will have to do something else first. Namely, emergency workers must find and fix the cracks and holes in the containment vessels of the damaged reactors that continue to allow contaminated, radioactive water to leak into the reactor buildings, the surrounding tunnels and neighboring facilities, and onto the ground, possibly into the ground water, and, almost certainly, into the sea. Yet, the problem of fixing the holes, a goal that was part of the previous plan of action, a goal that has not been met, is not in the latest Japanese report.

When asked about the omission, officials said that they expect progress to be made on the leaks. They did not say how. They did not say when. But, you know, obviously, that will be addressed. The main thing is, though, focus on the big, happy, longer-term goals.

Is this starting to sound at all familiar?

In the current context, I can certainly find fault with many of the details, but let’s say, OK, long-term deficit reduction is not a bad goal, in and of itself. It would, in theory, be good to spend less on interest, and more, say on education or infrastructure. . . .

But that is not how I hear President Obama addressing this. Instead, I hear him mimicking self-interested deficit hawks, blurring the difference between debt and deficit, allowing the Tea-OP to frame budget cuts as linked to the debt ceiling, and purposely dragging entitlements into the mix when they don’t have a bearing on the matter at hand. And, worst of all, the president and practically every other leader in DC has made deficit reduction the stand-in for the warm, fuzzy goal of rebuilding the economy—which is, at best, putting the cart before the horse, but is more likely a damaging and dangerous lie.

Before we get to jump in to the magic happy balanced-budget pool, perhaps there are a few holes and cracks the administration might want to spackle. And the cracks are legion, aren’t they?

Of course, there is the war. . . the wars. . . the three, three-and-a-half, or four wars, sucking trillions out of the economy.

And, of course, there are the very-much-still-here-even-though-they-should-have-already-expired Bush-era tax cuts for the wealthiest of the wealthy. And there is the hedge-fund-manager’s loophole and any number of other breaks for the rich that deprive the supposedly going-up-in-flames system of a cooling river of cash.

But I want to talk about an even more obvious, immediate, gaping hole, a hole that should be goal one in any discussion of the economy, and yet is embarrassingly absent from the beltway back-and-forth:

Jobs.

Before we spend another breath of air or drop of ink on the goal of deficit reduction, the federal government should be focusing on the goal of decreasing unemployment—focusing on the goal of creating jobs. It is, in fact, the obvious first step, the obvious hole you plug on the way to broader economic health. With more and better-paying jobs, you pump more money into the marketplace, increase demand, and spur expansion. And you also create a more robust revenue stream for the government. Almost every new job is a new taxable income.

And right now, when interest rates are so extremely low, when money is cheap for the government, now is an excellent time to invest in the country by spending. You know what would make this a less-good time for borrowing? Defaulting on our debt.

If the jerk circus in Washington fails to raise the debt ceiling, sends a message that it is some degree less than a sure thing that America will honor its obligations, then the cost of borrowing could go up, and then maybe we have a real problem.

Now, if you were president, what frame would you rather be forced to defend?

Why not take advantage of this situation—which has the added advantage of being the truth—and demand a clean vote, and only a clean vote, on the debt ceiling? Why not tell the American people that if we do this, and keep the money supply cheap and fluid, then government can do what it is supposed to do—what it can do: care for its people, create jobs in a time of need, repair aging infrastructure, research and develop new, greener energy sources (hint, hint—which will not only wean us off of expensive oil and nuclear power, but it could help build the economic engine that could power the US economy for the next decade), and provide a better life for every level of society?

Then, when we are back on terra firma, when we have plugged the gaping hole, we can re-examine the big rosy budget goals. But then we can do so from a place of strength, do so from a place where we are not trying to bail out a sinking ship with a perforated bucket, do so without running from crisis to crisis like terrified citizens in some Japanese horror film.

Let’s at least try to learn one thing from the Fukushima crisis: Make our goal to fix the hole.

The Party Line – July 15, 2011: Japan’s PM Recommends Shift Away from Nuclear Power; US Report Recommends Regulatory Tweaks

Posted on by

While most of creation is still trying to predict if Congress will raise the debt ceiling, and what will happen to the economy if they don’t, I thought I’d spend some quality time with disasters quite present, and in some ways, quite predictable. I am talking about nuclear power in the wake of Japan’s Fukushima disaster.

As I detailed a few weeks back, Germany’s Prime Minister, Angela Merkel, announced a plan to shut down all of her country’s nuclear reactors by 2022. This week, Japanese PM Naoto Kan made similar noises:

We should reduce our dependence in a planned and gradual way, and in the future we should aim to get by with no nuclear energy. When we think of the magnitude of the risks involved with nuclear power, the safety measures we previously conceived are inadequate.

And, also this week, here in the United States, the Nuclear Regulatory Commission released, via its website, an 80-something-page report on the Japanese nuclear disaster [PDF], which included a series of recommendations for improving safety and disaster response at US nuclear power facilities.

Just doesn’t have the same oomph, does it? Kind of missing the gravity or sense of urgency of a head of state declaring an unambiguous move away from nuclear power, no?

Style points aside—I mean, you can hardly expect President Obama to break away from round-the-clock deficit hysteria to address a looming threat that also happens to siphon billions of dollars from federal coffers in the form of subsidies and loan guarantees—the content of the report itself, its findings and recommendations, also leave me feeling a bit underwhelmed.

As noted, the report is long–and it is dense–but as I understand it, the task force recommends that regulators pay more attention to what the report calls “low-likelihood, high-consequence events”. . . you know, like earthquakes and floods that damage nuclear reactors and safety systems.

Hard to argue with that. . . but then the task force also says that the sort of high-consequence disaster that happened in Japan can’t happen in the US—and that is a point that I and many experts and activists would argue against. To put it very briefly, the United States has many reactors past their projected life spans, many similar in design to Fukushima’s, and many built in areas vulnerable to seismic activity, floods and, yes, even tsunamis.

Also recommended, that the government standardize safety regulations and emergency response plans—and make them actual rules as opposed to voluntary industry initiatives (aka “suggestions”)—which is good as far as it goes, but in the wake of a multi-part AP exposé showing how the NRC conspired with the nuclear industry to lower safety standards, I’m thinking that doesn’t go that far.

Perhaps what is most important, however, is what’s missing from the Near-Term Task Force Review. As noted by Physicians for Social Responsibility, the report makes no recommendation for moving spent nuclear fuel from over-packed pools to hardened on-site storage. A striking omission considering that used fuel rods stored in pools inside the Fukushima reactor buildings were and continue to be a serious part of the crisis in Japan.

Also highlighted by PSR, though completely outside the prescribed scope of the investigation, the task force states that there is an “expectation of no significant radiological health effects” from the Fukushima disaster.

No significant radiological health effects. When I first read that, I assumed the NRC review was referring to the United States—an assertion that already strains credulity as far as I’m concerned, but one that can be debated, given the distance and the data (or paucity of data). But, as I read it—uh, re-read it—this “conclusion” is a general one, as in everywhere, as in an expectation of no significant radiological health effects in Japan.

Now, that assertion, without any long-term health screenings or any epidemiological studies, is as worthless as it is irresponsible, but to make such a statement a week after a Japanese report revealed that 45 percent of children in Fukushima Prefecture have thyroids that show evidence of exposure to radiation makes one wonder what the US task force used for data. . . or if they felt the need to use data at all. Also revealed at the end of June, soil samples from the city of Fukushima—an area well outside of the quarantine radius—contained radioactive cesium at levels 1.5 to 4.5 times greater than the legal limit. (Radioactive cesium 137 has a half-life of approximately 30 years and tends to accumulate in plant tissue and fungal spores.)

But wait, there’s more:

Another sample taken from a street ditch — where nuclear fallout often accumulates — registered as much as 931,000 becquerels per sq. meter, surpassing the 555,000 becquerels per sq. meter limit for compulsory resettlement in the 1986 Chernobyl nuclear accident. Samples from the other three locations measured between 326,000 and 384,000 becquerels per sq. meter.

An earlier survey on soil in the city of Fukushima by the science ministry has found 37,000 becquerels of radioactive substances per 1 kg — equivalent to 740,000 becquerels per sq. meter.

That’s Japan. Here in North America, we found out this week that the Environmental Protection Agency was measuring radioactive iodine in rainwater out west at levels 30, 40, and, in one case, 130 times what is considered the safety standard for drinking water. Granted, a drinking water standard is not the same as a rainwater measure (as I understand it, the drinking water standard is based on the chances that consumption of a glass a day for 30 years will result in cancer), but that does not mean that this revelation doesn’t raise many questions.

For instance, what about negative non-cancer health effects? Has rain-borne radiation contaminated reservoirs, wells, or watersheds? What about bioaccumulation, what about the radiation that winds up in and on plants and animals? And what about—and this has been one of my big questions since the early days of this crisis—what about other isotopes, ones with other deleterious health effects, ones with half-lives measured in decades (like Cs-137) as opposed to days (like I-131)? And, of course, since it has been determined that there is no such thing as a “safe” level of radiation exposure, no matter the source, shouldn’t the government do a better job of informing the public of any significant increases?

To that last point, the report on radioactive rainwater, which is from Heart of America Northwest, also revealed that, in many cases, there was a lag time of a week between the radiation readings and the posting of the information on the EPA’s RadNet website. So, even for those that could parse the data on the less-than-lay-friendly site, the news was nowhere close to real-time, and so nowhere close to immediate enough for individuals trying to assess risk and adjust behavior accordingly.

The same report notes that though the EPA says it stepped up rainwater sampling following the start of the nuclear disaster in Japan, several sites (Portland, OR, for example) do not show additional sample dates beyond the standard once per month. That leads one to assume that the EPA was less diligent than they claimed, but could it also be that the EPA collected samples but chose not to post the data? (That’s an honest question—I don’t know if the latter is possible, but it did occur to me.)

By the way, that increase in sampling—it ended on May 3. . . because, of course, the Fukushima crisis is over. . . .

But, of course, the crisis is not over. Beyond the melted cores in several Fukushima reactors—where Japanese response teams are still trying to understand the shape and temperature of fuel and the integrity of the containment vessels—there are the pools of spent fuel rods, still very radioactive, still sitting in reactor buildings without roofs (which were destroyed by hydrogen explosions in the days after the earthquake and tsunami). Those pools are still sending an unknown amount of radiation into the atmosphere, and those pools will remain exposed for months to come (the first attempt to cover one of the reactor buildings is expected in late September).

So, that’s a lot to digest—for me, yes, and maybe for you, too—but at least I am trying to take it all in. Did the NRC task force take in any of this before they issued their report? Did they digest it? Yes or no, I find their assertion of no significant radiological health effects hard to swallow.

The differences in the levels of response—Germany announcing a plan to end its use of nuclear power, and Japan’s PM stating that his country should do the same, versus the United States quietly releasing a wonky report with a set of recommendations for a sustained nuclear future—tells me that the US government will not learn the lessons of the Fukushima disaster, and I find that hard to stomach.
