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.

Two Years On, Fukushima Raises Many Questions, Provides One Clear Answer

Fukushima’s threats to health and the environment continue. (graphic: Surian Soosay via flickr)

You can’t say you have all the answers if you haven’t asked all the questions. So, at a conference on the medical and ecological consequences of the Fukushima nuclear disaster, held to commemorate the second anniversary of the earthquake and tsunami that struck northern Japan, there were lots of questions. Questions about what actually happened at Fukushima Daiichi in the first days after the quake, and how that differed from the official report; questions about what radionuclides were in the fallout and runoff, at what concentrations, and how far they have spread; and questions about what near- and long-term effects this disaster will have on people and the planet, and how we will measure and recognize those effects.

A distinguished list of epidemiologists, oncologists, nuclear engineers, former government officials, Fukushima survivors, anti-nuclear activists and public health advocates gathered at the invitation of The Helen Caldicott Foundation and Physicians for Social Responsibility to, if not answer all these question, at least make sure they got asked. Over two long days, it was clear there is much still to be learned, but it was equally clear that we already know that the downsides of nuclear power are real, and what’s more, the risks are unnecessary. Relying on this dirty, dangerous and expensive technology is not mandatory–it’s a choice. And when cleaner, safer, and more affordable options are available, the one answer we already have is that nuclear is a choice we should stop making and a risk we should stop taking.

“No one died from the accident at Fukushima.” This refrain, as familiar as multiplication tables and sounding about as rote when recited by acolytes of atomic power, is a close mirror to versions used to downplay earlier nuclear disasters, like Chernobyl and Three Mile Island (as well as many less infamous events), and is somehow meant to be the discussion-ender, the very bottom-line of the bottom-line analysis that is used to grade global energy options. “No one died” equals “safe” or, at least, “safer.” Q.E.D.

But beyond the intentional blurring of the differences between an “accident” and the probable results of technical constraints and willful negligence, the argument (if this saw can be called such) cynically exploits the space between solid science and the simple sound bite.

“Do not confuse narrowly constructed research hypotheses with discussions of policy,” warned Steve Wing, Associate Professor of Epidemiology at the University of North Carolina’s Gillings School of Public Health. Good research is an exploration of good data, but, Wing contrasted, “Energy generation is a public decision made by politicians.”

Surprisingly unsurprising

A public decision, but not necessarily one made in the public interest. Energy policy could be informed by health and environmental studies, such as the ones discussed at the Fukushima symposium, but it is more likely the research is spun or ignored once policy is actually drafted by the politicians who, as Wing noted, often sport ties to the nuclear industry.

The link between politicians and the nuclear industry they are supposed to regulate came into clear focus in the wake of the March 11, 2011 Tohoku earthquake and tsunami–in Japan and the United States.

The boiling water reactors (BWRs) that failed so catastrophically at Fukushima Daiichi were designed and sold by General Electric in the 1960s; the general contractor on the project was Ebasco, a US engineering company that, back then, was still tied to GE. General Electric had bet heavily on nuclear and worked hand-in-hand with the US Atomic Energy Commission (AEC–the precursor to the NRC, the Nuclear Regulatory Commission) to promote civilian nuclear plants at home and abroad. According to nuclear engineer Arnie Gundersen, GE told US regulators in 1965 that without quick approval of multiple BWR projects, the giant energy conglomerate would go out of business.

It was under the guidance of GE and Ebasco that the rocky bluffs where Daiichi would be built were actually trimmed by 10 meters to bring the power plant closer to the sea, the water source for the reactors’ cooling systems–but it was under Japanese government supervision that serious and repeated warnings about the environmental and technological threats to Fukushima were ignored for another generation.

Failures at Daiichi were completely predictable, observed David Lochbaum, the director of the Nuclear Safety Project at the Union of Concerned Scientists, and numerous upgrades were recommended over the years by scientists and engineers. “The only surprising thing about Fukushima,” said Lochbaum, “is that no steps were taken.”

The surprise, it seems, should cross the Pacific. Twenty-two US plants mirror the design of Fukushima Daiichi, and many stand where they could be subject to earthquakes or tsunamis. Even without those seismic events, some US plants are still at risk of Fukushima-like catastrophic flooding. Prior to the start of the current Japanese crisis, the Nuclear Regulatory Commission learned that the Oconee Nuclear Plant in Seneca, South Carolina, was at risk of a major flood from a dam failure upstream. In the event of a dam breach–an event the NRC deems more likely than the odds that were given for the 2011 tsunami–the flood at Oconee would trigger failures at all four reactors. Beyond hiding its own report, the NRC has taken no action–not before Fukushima, not since.

The missing link

But it was the health consequences of nuclear power–both from high-profile disasters, as well as what is considered normal operation–that dominated the two days of presentations at the New York Academy of Medicine. Here, too, researchers and scientists attempted to pose questions that governments, the nuclear industry and its captured regulators prefer to ignore, or, perhaps more to the point, omit.

Dr. Hisako Sakiyama, a member of the Fukushima Nuclear Accident Independent Investigation Commission, has been studying the effects of low-dose radiation. Like others at the symposium, Dr. Sakiyama documented the linear, no-threshold risk model drawn from data across many nuclear incidents. In essence, there is no point at which it can be said, “Below this amount of radiation exposure, there is no risk.” And the greater the exposure, the greater the risk of health problems, be they cancers or non-cancer diseases.

Dr. Sakiyama contrasted this with the radiation exposure limits set by governments. Japan famously increased what it called acceptable exposure quite soon after the start of the Fukushima crisis, and, as global background radiation levels increase as a result of the disaster, it is feared this will ratchet up what is considered “safe” in the United States, as the US tends to discuss limits in terms of exposure beyond annual average background radiation. Both approaches lack credibility and expose an ugly truth. “Debate on low-dose radiation risk is not scientific,” explained Sakiyama, “but political.”

And the politics are posing health and security risks in Japan and the US.

Akio Matsumura, who spoke at the Fukushima conference in his role as founder of the Global Forum of Spiritual and Parliamentary Leaders for Human Survival, described a situation at the crippled Japanese nuclear plant that is much more perilous, even today, than leaders are willing to acknowledge. Beyond the precarious state of the spent fuel pool above reactor four, Matsumura also cited the continued melt-throughs of reactor cores (which could lead to a steam explosion), the high levels of radiation at reactors one and three (making any repairs impossible), and the unprotected pipes retrofitted to help cool reactors and spent fuel. “Probability of another disaster,” Matsumura warned, “is higher than you think.”

Matsumura lamented that investigations of both the technical failures and the health effects of the disaster are not well organized. “There is no longer a link between scientists and politicians,” said Matsumura, adding, “This link is essential.”

The Union of Concerned Scientists’ Lochbaum took it further. “We are losing the no-brainers with the NRC,” he said, implying that what should be accepted as basic regulatory responsibility is now subject to political debate. With government agencies staffed by industry insiders, “the deck is stacked against citizens.”

Both Lochbaum and Arnie Gundersen criticized the nuclear industry’s lack of compliance, even with pre-Fukushima safety requirements. And the industry’s resistance undermines nuclear’s claims of being competitive on price. “If you made nuclear power plants meet existing law,” said Gundersen, “they would have to shut because of cost.”

But without stronger safety rules and stricter enforcement, the cost is borne by people instead.

Determinate data, indeterminate risk

While the two-day symposium was filled with detailed discussions of chemical and epidemiologic data collected throughout the nuclear age–from Hiroshima through Fukushima–a cry for more and better information was a recurring theme. In a sort of wily corollary to “garbage in, garbage out,” experts bemoaned what seem like deliberate holes in the research.

Even the long-term tracking study of those exposed to the radiation and fallout in Japan after the atomic blasts at Hiroshima and Nagasaki–considered by many the gold-standard in radiation exposure research because of the large sample size and the long period of time over which data was collected–raises as many questions as it answers.

The Hiroshima-Nagasaki data was referenced heavily by Dr. David Brenner of the Center for Radiological Research, Columbia University College of Physicians and Surgeons. Dr. Brenner praised the study while using it to buttress his opinion that, while harm from any nuclear event is unfortunate, the Fukushima crisis will result in relatively few excess cancer deaths–something like 500 in Japan, and an extra 2,000 worldwide.

“There is an imbalance of individual risk versus overall anxiety,” said Brenner.

But Dr. Wing, the epidemiologist from the UNC School of Public Health, questioned the reliance on the atom bomb research, and the relatively rosy conclusions those like Dr. Brenner draw from it.

“The Hiroshima and Nagasaki study didn’t begin till five years after the bombs were dropped,” cautioned Wing. “Many people died before research even started.” The examination of cancer incidence in the survey, Wing continued, didn’t begin until 1958–it misses the first 13 years of data. Research on “Black Rain” survivors (those who lived through the heavy fallout after the Hiroshima and Nagasaki bombings) excludes important populations from the exposed group, despite those populations’ high excess mortality, thus driving down reported cancer rates for those counted.

The paucity of data is even more striking in the aftermath of the Three Mile Island accident, and examinations of populations around American nuclear power plants that haven’t experienced high-profile emergencies are even scarcer. “Studies like those done in Europe have never been done in the US,” said Wing with noticeable regret. Wing observed that a German study has shown increased incidences of childhood leukemia near operating nuclear plants.

There is relatively more data on populations exposed to radioactive contamination in the wake of the Chernobyl nuclear accident. Yet, even in this catastrophic case, the fact that the data has been collected and studied owes much to the persistence of Alexey Yablokov of the Russian Academy of Sciences. Yablokov has been examining Chernobyl outcomes since the early days of the crisis. His landmark collection of medical records and the scientific literature, Chernobyl: Consequences of the Catastrophe for People and the Environment, has its critics, who fault its strong warnings about the long-term dangers of radiation exposure, but it is that strident tone that Yablokov himself said was crucial to the evolution of global thinking about nuclear accidents.

Because of pressure from the scientific community and, as Yablokov stressed at the New York conference, pressure from the general public, as well, reaction to accidents since Chernobyl has evolved from “no immediate risk,” to small numbers who are endangered, to what is now called “indeterminate risk.”

Calling risk “indeterminate,” believe it or not, actually represents a victory for science, because it means more questions are asked–and asking more questions can lead to more and better answers.

Yablokov made it clear that it is difficult to estimate the real individual radiation dose–too much data is not collected early in a disaster, fallout patterns are patchy and different groups are exposed to different combinations of particles–but he drew strength from the volumes and variety of data he’s examined.

Indeed, as fellow conference participant, radiation biologist Ian Fairlie, observed, people can criticize Yablokov’s advocacy, but the data is the data, and in the Chernobyl book, there is lots of data.

Complex and consequential

Data presented at the Fukushima symposium also included much on what might have been–and continues to be–released by the failing nuclear plant in Japan, and how that contamination is already affecting populations on both sides of the Pacific.

Several of those present emphasized the need to better track releases of noble gasses, such as xenon-133, from the earliest days of a nuclear accident–both because of the dangers these elements pose to the public and because gas releases can provide clues to what is unfolding inside a damaged reactor. But more is known about the high levels of radioactive iodine and cesium contamination that have resulted from the Fukushima crisis.

In the US, since the beginning of the disaster, five west coast states have measured elevated levels of iodine-131 in air, water and kelp samples, with the highest airborne concentrations detected from mid-March through the end of April 2011. Iodine concentrates in the thyroid, and, as noted by Joseph Mangano, director of the Radiation and Public Health Project, fetal thyroids are especially sensitive. In the 15 weeks after fallout from Fukushima crossed the Pacific, the western states reported a 28-percent increase in newborn (congenital) hypothyroidism (underactive thyroid), according to the Open Journal of Pediatrics. Mangano contrasted this with a three-percent drop in the rest of the country during the same period.

The most recent data from Fukushima prefecture shows over 44 percent of children examined there have thyroid abnormalities.

Of course, I-131 has a relatively short half-life; radioactive isotopes of cesium will have to be tracked much longer.

With four reactors and densely packed spent fuel pools involved, Fukushima Daiichi’s “inventory” (as it is called) of cesium-137 dwarfed Chernobyl’s at the time of its catastrophe. Consequently, and contrary to some of the spin out there, the Cs-137 emanating from the Fukushima plant is also out-pacing what happened in Ukraine.

Estimates put the release of Cs-137 in the first months of the Fukushima crisis at between 64 and 114 petabecquerels (this number includes the first week of aerosol release and the first four months of ocean contamination). And the damaged Daiichi reactors continue to add an additional 240 million becquerels of radioactive cesium to the environment every single day. Chernobyl’s cesium-137 release is pegged at about 84 petabecquerels. (One petabecquerel equals 1,000,000,000,000,000 becquerels.) By way of comparison, the nuclear “device” dropped on Hiroshima released 89 terabecquerels (1,000 terabecquerels equal one petabecquerel) of Cs-137, or, to put it another way, Fukushima has already released more than 6,400 times as much radioactive cesium as the Hiroshima bomb.

The effects of elevated levels of radioactive cesium are documented in several studies across post-Chernobyl Europe, but while the implications for public health are significant, they are also hard to contain in a sound bite. As medical genetics expert Wladimir Wertelecki explained during the conference, a number of cancers and other serious diseases emerged over the first decade after Chernobyl, but the cycles of farming, consuming, burning and then fertilizing with contaminated organic matter will produce illness and genetic abnormalities for many decades to come. Epidemiological studies are only descriptive, Wertelecki noted, but they can serve as a “foundation for cause and effect.” The issues ahead for all of those hoping to understand the Fukushima disaster and the repercussions of the continued use of nuclear power are, as Wertelecki pointed out, “Where you study and what you ask.”

One of the places that will need some of the most intensive study is the Pacific Ocean. Because Japan is an island, most of Fukushima’s fallout plume drifted out to sea. Perhaps more critically, millions of gallons of water have been pumped into and over the damaged reactors and spent fuel pools at Daiichi, and because of still-unplugged leaks, some of that water flows into the ocean every day. (And even if those leaks are plugged and the nuclear fuel is stabilized someday, mountain runoff from the area will continue to discharge radionuclides into the water.) Fukushima’s fisheries are closed and will remain so as far into the future as anyone can anticipate. Bottom feeders and freshwater fish exhibit the worst levels of cesium, but they are only part of the picture. Ken Beusseler, a marine scientist at Woods Hole Oceanographic Institute, described a complex ecosystem of ocean currents, food chains and migratory fish, some of which carry contamination with them, some of which actually work cesium out of their flesh over time. The seabed and some beaches will see increases in radio-contamination. “You can’t keep just measuring fish,” warned Beusseler, implying that the entire Pacific Rim has involuntarily joined a multidimensional long-term radiation study.

For what it’s worth

Did anyone die as a result of the nuclear disaster that started at Fukushima Daiichi two years ago? Dr. Sakiyama, the Japanese investigator, told those assembled at the New York symposium that 60 patients died while being moved from hospitals inside the radiation evacuation zone–does that count? Joseph Mangano has reported on increases in infant deaths in the US following the arrival of Fukushima fallout–does that count? Will cancer deaths or future genetic abnormalities, be they at the low or high end of the estimates, count against this crisis?

It is hard to judge these answers when the question is so very flawed.

As discussed by many of the participants throughout the Fukushima conference, a country’s energy decisions are rooted in politics. Nuclear advocates would have you believe that their favorite fuel should be evaluated inside an extremely limited universe, that there is some level of nuclear-influenced harm that can be deemed “acceptable,” that questions stem from the necessity of atomic energy instead of from whether civilian nuclear power is necessary at all.

The nuclear industry would have you do a cost-benefit analysis, but they’d get to choose which costs and benefits you analyze.

While all this time has been and will continue to be spent on tracking the health and environmental effects of nuclear power, it isn’t a fraction of a fraction of the time that the world will be saddled with fission’s dangerous high-level radioactive trash (a problem without a real temporary storage program, forget a permanent disposal solution). And for all the money that has been and will continue to be spent compiling the health and environmental data, it is a mere pittance when compared with the government subsidies, liability waivers and loan guarantees lavished upon the owners and operators of nuclear plants.

Many individual details will continue to emerge, but a basic fact is already clear: nuclear power is not the world’s only energy option. Nor are the choices limited to just fossil and fissile fuels. Nuclear lobbyists would love to frame the debate–as would advocates for natural gas, oil or coal–as cold calculations made with old math. But that is not where the debate really resides.

If nuclear reactors were the only way to generate electricity, would 500 excess cancer deaths be acceptable? How about 5,000? How about 50,000? If nuclear’s projected mortality rate comes in under coal’s, does that make the deaths–or the high energy bills, for that matter–more palatable?

As the onetime head of the Tennessee Valley Authority, David Freeman, pointed out toward the end of the symposium, every investment in a new nuclear, gas or coal plant is a fresh 40-, 50-, or 60-year commitment to a dirty, dangerous and outdated technology. Every favor the government grants to nuclear power triggers an intense lobbying effort on behalf of coal or gas, asking for equal treatment. Money spent bailing out the past could be spent building a safer and more sustainable future.

Nuclear does not exist in a vacuum; so neither do its effects. There is much more to be learned about the medical and ecological consequences of the Fukushima nuclear disaster–but that knowledge should be used to minimize and mitigate the harm. These studies do not ask and are not meant to answer, “Is nuclear worth it?” When the world already has multiple alternatives–not just in renewable technologies, but also in conservation strategies and improvements in energy efficiency–the answer is already “No.”

Imagine a Nuclear-Free California (You Don’t Have To, It’s Already Here)

Posted on by

We welcome our salp overlords. (A chain of salp in the Red Sea; photo: Lars Plougman via Wikipedia)

California has two nuclear power plants. San Onofre, between Los Angeles and San Diego, has been offline for months as everyone tries to find an excuse for the alarmingly rapid wear on new reactor tubing. (Being shut down, however, did not prevent a fire from breaking out this week when a pipe ruptured and released radioactive steam.)

But as of Thursday, Diablo Canyon, the nuclear plant to the north, is also offline–thanks to. . . uh, salp?

Yes, salp–those loveable, gelatinous, jellyfish-like, plankton-eating sea creatures that multiply like, well, salp–have swarmed Diablo Canyon’s water intake system. D-Can draws in tens of thousands of gallons of seawater every day to cool its reactors, and with all that salp clogging the intake pipes, the plant could no longer operate safely.

That may sound like a freak event, but it isn’t. San Onofre had to shut down in 2005 to clear out 11,000 pounds of anchovies that had the bad luck of swimming too close to that plant’s intake filters. . . and in 2004, it shut down, too, but that time it was due to 14,000 pounds of sardines.

And just last year, actual jellyfish (sorry, salps) brought down Florida Power & Light’s St. Lucie nuclear power station. Jellyfish have also previously crippled nuclear facilities in the UK, Israel and Japan.

But back to California, where without nuclear power, the state is heading for a disaster of biblical proportions–we’re talking human sacrifice, dogs and cats living together, mass hysteria!

Actually, no. What will happen is that Pacific Gas & Electric, the owner of Diablo Canyon, and Southern California Edison, San Onofre’s operator, will have to buy electricity (or continue to buy electricity) in order to deliver what they are obligated to deliver. That’s no fun for the big utilities, and maybe it looks biblical to the bean counters, but it is not an energy apocalypse.

Of course, instead of throwing millions after billions to buy surplus electricity elsewhere while also paying to staff, examine and repair its dormant, ancient nuclear facilities, power companies could try to invest more in 21st Century renewable alternatives.

And maybe that would happen if the market were actually, you know, a market. But with tax breaks, loan guarantees, and liability caps, the industry has little motivation to make sound financial or environmental decisions.

But there’s no time like the present to start. And right now, in California, that present is nuclear-free.

A little bit pregnant?

On Thursday, NPR’s Richard Harris delivered a report that regurgitated the nuclear industry’s latest message morph–once “clean, safe, and too cheap to meter,” the 21st Century PR spin has nuclear as the climate-friendly energy option.

The radio piece is ostensibly about how the world’s industrialized nations are failing to meet their climate goals–and this is true (and this is a problem). But Harris does the world and the climate cause no favors when he lazily posits: “Nuclear power produces very little carbon dioxide. . . .”

What does Harris mean by “nuclear power produces very little carbon dioxide?” Is that supposed to be a hedge? If you are isolating the atomic pile generating heat to boil water inside a closed system, then you might as well say “no CO2,” but if you are honest and take into account the whole lifecycle of nuclear fuel–from mining and refining through transportation and storage–then nuclear power produces a prodigious amount of greenhouse gases. Which is it Richard?

Probably just an oversight

The Washington Post published self-serving letter to the editor supporting a recent pro-nuclear editorial, but neglected to include that the letter was written by the current vice president and president elect and sitting member of the board of directors of the unabashedly pro-nuclear American Nuclear Society.

If only Nixon had apologized!

Fukushima Governor Yuhei Sato apologized Wednesday for prefectural officials who deleted records on the spread of radioactive fallout immediately following the start of the Daiichi nuclear crisis in March of 2011. The data from the country’s System for Prediction of Environmental Emergency Dose Information (SPEEDI) could have better informed citizens on when and where to evacuate during the first days after the Tohoku quake and tsunami destroyed safety systems at the Fukushima Daiichi nuclear power plant, and could have also given those trying to piece together what happened inside the reactors important forensic evidence.

At a news conference, Sato said, “A big problem lies in the fact that we failed to fully share the information soon after the nuclear disaster broke out.”

Well, yeah, that–and that you erased it.

Not to worry though, the government “reprimanded” its supervising officials and also “issued strong warnings” to the two government employees that actually did the deleting. So, citizens of Northern Japan, we’re good?

“Let’s Eat Cesium Beef”

That is (as translated by EXSKF) the name of an event in Iwate, Japan designed to encourage people to eat local beef known to be contaminated with radioactive cesium from Fukushima’s fallout.

No, this did not appear in a Japanese version of The Onion (Tamanegi?), this a real event as reported by Kyodo News in a series called “New Happiness in Japan.” Apparently, happiness is knowing you’re only poisoning your children a little bit. . . because there were kids at this thing.

The event was, uh, cooked up by the head of a meat-packing company to show a group of his regular customers–including young couples with kids–that beef containing radioactive cesium, but at levels lower than the provisional safety limits, still tasted OK.

According to the source of the translation, this story has people all over Japan shaking their heads wondering what this meat packer could have been thinking, but there have been several stories over the past year documenting even more official Japanese government efforts to get citizens to consume agricultural products from Fukushima and surrounding regions.

Imagine a nuclear-free Japan

Soon, you won’t have to imagine that, either. The last of Japan’s 50 commercial reactors still online will soon shut down.

Wait? Fifty? Wasn’t it 54? Well, earlier this month, Japan removed the four damaged reactors at Fukushima Daiichi from their official list of the country’s commercial reactors.

Probably wise.

Oh, and, notice, also no mass hysteria. The radiation that has contaminated air, water, and land might have many Japanese very worried, but the country has managed to handle the reduced electrical generating capacity remarkably well. They did this thing called “conservation.” Been doing it for over a year now. Think of all the dogs and cats that have been spared. . . not to mention the salp.

Something Fishy: CRS Report Downplays Fukushima’s Effect on US Marine Environment

Posted on by

Late Thursday, the United States Coast Guard reported that they had successfully scuttled the Ryou-Un Maru, the Japanese “Ghost Ship” that had drifted into US waters after being torn from its moorings by the tsunami that followed the Tohoku earthquake over a year ago. The 200-foot fishing trawler, which was reportedly headed for scrap before it was swept away, was seen as potentially dangerous as it drifted near busy shipping lanes.

Coincidentally, the “disappearing” of the Ghost Ship came during the same week the Congressional Research Service (CRS) released its report on the effects of the Fukushima Daiichi nuclear disaster on the US marine environment, and, frankly, the metaphor couldn’t be more perfect. The Ryou-Un Maru is now resting at the bottom of the ocean–literally nothing more to see there, thanks to a few rounds from a 25mm Coast Guard gun–and the CRS hopes to dispatch fears of the radioactive contamination of US waters and seafood with the same alacrity.

But while the Ghost Ship was not considered a major ecological threat (though it did go down with around 2,000 gallons of diesel fuel in its tanks), the US government acknowledges that this “good luck ship” (a rough translation of its name) is an early taste of the estimated 1.5 million tons of tsunami debris expected to hit North American shores over the next two or three years. Similarly, the CRS report (titled Effects of Radiation from Fukushima Dai-ichi on the U.S. Marine Environment [PDF]) adopts an overall tone of “no worries here–its all under control,” but a closer reading reveals hints of “more to come.”

Indeed, the report feels as it were put through a political rinse cycle, limited both in the strength of its language and the scope of its investigation. This tension is evident right from the start–take, for example, these three paragraphs from the report’s executive summary:

Both ocean currents and atmospheric winds have the potential to transport radiation over and into marine waters under U.S. jurisdiction. It is unknown whether marine organisms that migrate through or near Japanese waters to locations where they might subsequently be harvested by U.S. fishermen (possibly some albacore tuna or salmon in the North Pacific) might have been exposed to radiation in or near Japanese waters, or might have consumed prey with accumulated radioactive contaminants.

High levels of radioactive iodine-131 (with a half-life of about 8 days), cesium-137 (with a half-life of about 30 years), and cesium-134 (with a half-life of about 2 years) were measured in seawater adjacent to the Fukushima Dai-ichi site after the March 2011 events. EPA rainfall monitors in California, Idaho, and Minnesota detected trace amounts of radioactive iodine, cesium, and tellurium consistent with the Japanese nuclear incident, at concentrations below any level of concern. It is uncertain how precipitation of radioactive elements from the atmosphere may have affected radiation levels in the marine environment.

Scientists have stated that radiation in the ocean very quickly becomes diluted and would not be a problem beyond the coast of Japan. The same is true of radiation carried by winds. Barring another unanticipated release, radioactive contaminants from Fukushima Dai-ichi should be sufficiently dispersed over time that they will not prove to be a serious health threat elsewhere, unless they bioaccumulate in migratory fish or find their way directly to another part of the world through food or other commercial products.

Winds and currents have “the potential” to transport radiation into US waters? Winds–quite measurably–already have, and computer models show that currents, over the next couple of years, most certainly will.

Are there concentrations of radioisotopes that are “below concern?” No reputable scientist would make such a statement. And if monitors in the continental United States detected radioactive iodine, cesium and tellurium in March 2011, then why did they stop the monitoring (or at least stop reporting it) by June?

The third paragraph, however, wins the double-take prize. Radiation would not be a problem beyond the coast? Fish caught hundreds of miles away would beg to differ. “Barring another unanticipated release. . . ?” Over the now almost 13 months since the Fukushima crisis began, there have been a series of releases into the air and into the ocean–some planned, some perhaps unanticipated at the time, but overall, the pattern is clear, radioactivity continues to enter the environment at unprecedented levels.

And radioactive contaminants “should be sufficiently dispersed over time, unless they bioaccumulate?” Unless? Bioaccumulation is not some crazy, unobserved hypothesis, it is a documented biological process. Bioaccumulation will happen–it will happen in migratory fish and it will happen as under-policed food and commercial products (not to mention that pesky debris) make their way around the globe.

Maybe that is supposed to be read by inquiring minds as the report’s “please ignore he man behind the curtain” moment–an intellectual out clause disguised as an authoritative analgesic–but there is no escaping the intent. Though filled with caveats and counterfactuals, the report is clearly meant to serve as a sop to those alarmed by the spreading ecological catastrophe posed by the ongoing Fukushima disaster.

The devil is in the details–the dangers are in the data

Beyond the wiggle words, perhaps the most damning indictment of the CRS marine radiation report can be found in the footnotes–or, more pointedly, in the dates of the footnotes. Though this report was released over a year after the Tohoku earthquake and tsunami triggered the Fukushima nightmare, the CRS bases the preponderance of its findings on information generated during the disaster’s first month. In fact, of the document’s 29 footnotes, only a handful date from after May 2011–one of those points to a CNN report (authoritative!), one to a status update on the Fukushima reactor structures, one confirms the value of Japanese seafood imports, three are items tracking the tsunami debris, and one directs readers to a government page on FDA radiation screening, the pertinent part of which was last updated on March 28 of last year.

Most crucially, the parts of the CRS paper that downplay the amounts of radiation measured by domestic US sensors all cite data collected within the first few weeks of the crisis. The point about radioisotopes being “below any level of concern” comes from an EPA news release dated March 22, 2011–eleven days after the earthquake, only six days after the last reported reactor explosion, and well before so many radioactive releases into the air and ocean. It is like taking reports of only minor flooding from two hours after Hurricane Katrina passed over New Orleans, and using them as the standard for levee repair and gulf disaster planning (perhaps not the best example, as many have critiqued levee repairs for their failure to incorporate all the lessons learned from Katrina).

It now being April of 2012, much more information is available, and clearly any report that expects to be called serious should have included at least some of it.

By October of last year, scientists were already doubling their estimates of the radiation pushed into the atmosphere by the Daiichi reactors, and in early November, as reported here, France’s Institute for Radiological Protection and Nuclear Safety issued a report showing the amount of cesium 137 released into the ocean was 30 times greater than what was stated by TEPCO in May. Shockingly, the Congressional Research Service does not reference this report.

Or take the early March 2012 revelation that seaweed samples collected from off the coast of southern California show levels of radioactive iodine 131 500 percent higher than those from anywhere else in the US or Canada. It should be noted that this is the result of airborne fallout–the samples were taken in mid-to-late-March 2011, much too soon for water-borne contamination to have reached that area–and so serves to confirm models that showed a plume of radioactive fallout with the greatest contact in central and southern California. (Again, this specific report was released a month before the CRS report, but the data it uses were collected over a year ago.)

Then there are the food samples taken around Japan over the course of the last year showing freshwater and sea fish–some caught over 200 kilometers from Fukushima–with radiation levels topping 100 becquerels per kilogram (one topping 600 Bq/kg).

And the beat goes on

This information, and much similar to it, was all available before the CRS released its document, but the report also operates in a risibly artificial universe that assumes the situation at Fukushima Daiichi has basically stabilized. As a sampling of pretty much any week’s news will tell you, it has not. Take, for example, this week:

About 12 tons of water contaminated with radioactive strontium are feared to have leaked from the Fukushima No. 1 plant into the Pacific Ocean, Tepco said Thursday.

The leak occurred when a pipe broke off from a joint while the water was being filtered for cesium, Tokyo Electric Power Co. said.

The system doesn’t remove strontium, and most of the water apparently entered the sea via a drainage route, Tepco added.

The water contained 16.7 becquerels of cesium per cu. centimeter and tests are under way to determine how much strontium was in it, Tepco said.

This is the second such leak in less than two weeks, and as Kazuhiko Kudo, a professor of nuclear engineering at Kyushu University who visited Fukushima Daiichi twice last year, noted:

There will be similar leaks until Tepco improves equipment. The site had plastic pipes to transfer radioactive water, which Tepco officials said are durable and for industrial use, but it’s not something normally used at nuclear plants. Tepco must replace it with metal equipment, such as steel.

(The plastic tubes–complete with the vinyl and duct tape patch–can be viewed here.)

And would that the good people at the Congressional Research Service could have waited to read a report that came out the same day as theirs:

Radioactive material from the Fukushima nuclear disaster has been found in tiny sea creatures and ocean water some 186 miles (300 kilometers) off the coast of Japan, revealing the extent of the release and the direction pollutants might take in a future environmental disaster.

In some places, the researchers from Woods Hole Oceanographic Institution (WHOI) discovered cesium radiation hundreds to thousands of times higher than would be expected naturally, with ocean eddies and larger currents both guiding the “radioactive debris” and concentrating it.

Or would that the folks at CRS had looked to their fellow government agencies before they went off half-cocked. (The study above was done by researchers at Woods Hole and written up in the journal of the National Academy of Sciences.) In fact, it appears the CRS could have done that. In its report, CRS mentions that “Experts cite [Fukushima] as the largest recorded release of radiation to the ocean,” and the source for that point is a paper by Ken Buesseler–the same Ken Buesseler that was the oceanographer in charge of the WHOI study. Imagine what could have been if the Congressional Research Service had actually contacted the original researcher.

Can openers all around

Or perhaps it wouldn’t have mattered. For if there is one obvious takeaway from the CRS paper, beyond its limits of scope and authority, that seeks to absolve it of all other oversights–it is its unfailing confidence in government oversight.

Take a gander at the section under the bolded question “Are there implications for US seafood safety?”:

It does not appear that nuclear contamination of seafood will be a food safety problem for consumers in the United States. Among the main reasons are that:

  • damage from the disaster limited seafood production in the affected areas,
  • radioactive material would be diluted before reaching U.S. fishing grounds, and
  • seafood imports from Japan are being examined before entry into the United States.

According to the U.S. Food and Drug Administration (FDA), because of damage from the earthquake and tsunami to infrastructure, few if any food products are being exported from the affected region. For example, according to the National Federation of Fisheries Cooperative Associations, the region’s fishing industry has stopped landing and selling fish. Furthermore, a fishing ban has been enforced within a 2-kilometer radius around the damaged nuclear facility.

So, the Food and Drug Administration is relying on the word of an industry group and a Japanese government-enforced ban that encompasses a two-kilometer radius–what link of that chain is supposed to be reassuring?

Last things first: two kilometers? Well, perhaps the CRS should hire a few proofreaders. A search of the source materials finds that the ban is supposed to be 20-kilometers. Indeed, the Japanese government quarantined the land for a 20-kilometer radius. The US suggested evacuation from a 50-mile (80-kilometer) radius. The CRS’s own report notes contaminated fish were collected 30 kilometers from Fukushima. So why is even 20 kilometers suddenly a radius to brag about?

As for a damaged industry not exporting, numerous reports show the Japanese government stepping in to remedy that “problem.” From domestic PR campaigns encouraging the consumption of foodstuffs from Fukushima prefecture, to the Japanese companies selling food from the region to other countries at deep discounts, to the Japanese government setting up internet clearing houses to help move tainted products, all signs point to a power structure that sees exporting possibly radioactive goods as essential to its survival.

The point on dilution, of course, not only ignores the way many large scale fishing operations work, it ignores airborne contamination and runs counter to the report’s own acknowledgment of bioaccumulation.

But maybe the shakiest assertion of all is that the US Food and Drug Administration will stop all contaminated imports at the water’s edge. While imports hardly represent the total picture when evaluating US seafood safety, taking this for the small slice of the problem it covers, it engenders raised eyebrows.

First there is the oft-referenced point from nuclear engineer Arnie Gundersen, who said last summer that State Department officials told him of a secret agreement between Japan and Secretary Hilary Clinton guaranteeing the continued importation of Japanese food. While independent confirmation of this pact is hard to come by, there is the plain fact that, beyond bans on milk, dairy products, fruits and vegetables from the Fukushima region issued in late March 2011, the US has proffered no other restrictions on Japanese food imports (and those few restrictions for Japanese food were lifted for US military commissaries in September).

And perhaps most damning, there was the statement from an FDA representative last April declaring that North Pacific seafood was so unlikely to be contaminated that “no sampling or monitoring of our fish is necessary.” The FDA said at the time that it would rely on the National Oceanographic and Atmospheric Administration (NOAA) to tell it when they should consider testing seafood, but a NOAA spokesperson said it was the FDA’s call.

Good. Glad that’s been sorted out.

The Congressional Research Service report seems to fall victim to a problem noted often here–they assume a can opener. As per the joke, the writers stipulate a functioning mechanism before explaining their solution. As many nuclear industry-watchers assume a functioning regulatory process (as opposed to a captured Nuclear Regulatory Commission, an industry-friendly Department of Energy, and industry-purchased members of Congress) when speaking of the hypothetical safety of nuclear power, the CRS here assumes an FDA interested first and foremost in protecting the general public, instead of an agency trying to strike some awkward “balance” between health, profit and politics. The can opener story is a joke; the effects of this real-life example are not.

Garbage in, garbage out

The Congressional Research Service, a part of the Library of Congress, is intended to function as the research and analysis wing of the US Congress. It is supposed to be objective, it is supposed to be accurate, and it is supposed to be authoritative. America needs the CRS to be all of those things because the agency’s words are expected to inform federal legislation. When the CRS shirks its responsibility, shapes its words to fit comfortably into the conventional wisdom, or shaves off the sharp corners to curry political favor, the impact is more than academic.

When the CRS limits its scope to avoid inconvenient truths, it bears false witness to the most important events of our time. When the CRS pretends other government agencies are doing their jobs–despite documentable evidence to the contrary–then they are not performing theirs. And when the CRS issues a report that ignores the data and the science so that a few industries might profit, it is America that loses.

The authors of this particular report might not be around when the bulk of the cancers and defects tied to the radiation from Fukushima Daiichi present in the general population, but this paper’s integrity today could influence those numbers tomorrow. Bad, biased, or bowdlerized advice could scuttle meaningful efforts to make consequential policy.

If the policy analysts that sign their names to reports like this don’t want their work used for scrap paper, then maybe they should take a lesson from the Ryou-Un Maru. Going where the winds and currents take you makes you at best a curiosity, and more likely a nuisance–just so much flotsam and jetsam getting in the way of actual business. Works of note come with moral rudders, anchored to best data available; without that, the report might as well just say “good luck.”

Gregory Jaczko Has a Cold

Posted on by

NRC Chairman Gregory Jaczko (photo: pennstatelive)

In April 1966, Esquire Magazine published a story by Gay Talese that is still considered one of the greatest magazine articles of all time; the article, the cover story, was titled “Frank Sinatra Has a Cold.”

The piece, still very much worth the read, says much about celebrity, journalism, and, of course, celebrity journalism, but germane here is a point Talese makes early on: for most people, having a cold is a trivial matter–after all, it’s called the “common” cold–but when a man, a cultural icon, a giant of stage and screen like Sinatra (remember, this is 1966) has a cold, well. . . .

Frank Sinatra with a cold is a big deal. It affects him, his mood, his ability to perform, and so it affects his friends, his entourage, his personal staff of 75, his audience, and perhaps a part of the greater popular culture. In other words, as Talese wants you to understand, in this case, a cold is anything but trivial.

Gregory Jaczko, the chairman of the United States Nuclear Regulatory Commission, made some comments to the press earlier this week. Jaczko, it seems, is worried. He believes, as noted in an Associated Press story, that “U.S. nuclear plant operators have become complacent, just nine months after the nuclear disaster in Japan.” The NRC head thinks that a slew of events at over a dozen domestic nuclear facilities reveal the safety of America’s reactors to be something less than optimal.

To be clear, safety concerns at any kind of plant, be it a soda bottler or a microchip manufacturer, are probably not trivial, but when the safe and secure operation of a nuclear facility comes into question–as the aftermath of Chernobyl or the ongoing crisis in Japan will tell you–it ratchets up concern to a whole different level. So, when the man who more or less serves as the chief safety officer for the entirety of the nation’s nuclear infrastructure says he’s worried, many, many other people should be worried, too.

To put it another way, Greg Jaczko has a cold.

But that’s not the scariest part.

When Frank Sinatra had a cold, he knew he had a cold–pretty much everyone knew he had a cold. It was unpleasant for all of them, but forewarned is forearmed. Jaczko, though, doesn’t know–or won’t acknowledge–he’s sick. As relayed by the AP:

Jaczko said he was not ready to declare a decline in safety performance at U.S. plants, but said problems were serious enough to indicate a “precursor” to a performance decline.

Pardon my acronym, but WTF does “‘precursor’ to a performance decline” mean?

It sounds like a way to talk about erectile dysfunction, but perhaps a more accurate analogy is to say that Greg Jaczko has just told us that, yes, actually, you can be a little bit pregnant.

Of course, that is not true. Either safety–with regards to protocols, equipment and people–is up to snuff, or it is not. As Jaczko observes–and the many “unusual events” he has had to deal with this year make clear–the safety of America’s nuclear reactors is not where it needs to be:

Mr. Jaczko said the NRC has noticed an increase in “possible declines in performance” at some U.S. nuclear facilities, including instances of human error that almost exposed workers to high levels of radiation. He said a number of nuclear plants have experienced safety challenges in recent months, and that two of the plants were having significant issues.

The chairman’s classic understatement here is magnified by the Wall Street Journal. Beyond the fact that “possible declines in performance” means flat-out “declines in performance,” the human error referred to here didn’t “almost” expose workers to high levels of radiation–the accidents at Cooper Nuclear Station in Nebraska and the Perry Nuclear Power Plant in Ohio most definitively exposed workers to high (and possibly dangerously high) levels of radiation.

And the two plants having significant issues–which would those be? Would they be Crystal River in Florida, where news of a third major crack in the containment building recently came to light, and Nebraska’s Fort Calhoun, which is still shut down after flooding earlier this year? Or might they be New Hampshire’s Seabrook, where crumbling concrete was discovered in November, a month after the plant had to shut down because of low water levels, and Vermont Yankee, where radioactive tritium continues to leak into the Connecticut River?

Or maybe Jaczko was referencing North Anna, which of course scrammed when the Mineral Springs, VA, earthquake shook the reactors well in excess of their designed tolerances. Or maybe he’s including Calvert Cliffs in Maryland, where a piece of siding blown off by Hurricane Irene shorted a transformer, and the resulting loss of power to safety systems caused its reactor to scram. And who can forget Michigan’s Palisades nuclear power plant, which had to vent radioactive steam when it scrammed after worker error triggered a series of electrical issues?

Is it possible the NRC head was thinking of the constantly troubled Davis-Besse plant near Toledo, Ohio? Probably not–since the Commission just (as in 4:40 PM on Friday, December 2) okayed a restart there, despite serious concerns about numerous cracks in its shield building. But perhaps Jaczko should think again–on December 7, one day after the reactor restart, FirstEnergy, Davis-Besse’s operator, admitted that they had withheld news of new cracks on a different part of the structure, which were discovered in November. (FirstEnergy says that they only withheld the information from the public, and that they did report it to regulators–which raises grave questions about the honesty, independence and competency of the NRC and how it could approve a restart.)

Representative Dennis Kucinich, by the way, is thinking of Davis-Besse. The Ohio Democrat had called for public hearings in advance of the restart, and is now criticizing both FirstEnergy and the NRC for their lack of candor about the new cracking.

Kucinich appears to understand something that Jaczko does not: when it comes to oversight of the nuclear industry, there is no room for even the germ of a doubt.

To extend the illness-as-metaphor metaphor a little further, there is a construction often used to imply the broadly felt repercussions of a single action or a major actor: When “x” sneezes, “y” catches a cold. The phrase is believed to have started during the worldwide depression that spread after the U.S. stock market crash of 1929–as in, “When America sneezes, the whole world catches cold.” The cliché has come back into vogue during the last three years of global economic tumult, but it could easily be adapted to the ongoing perils of nuclear power.

On November 26, the Asahi Shimbun gave the world another measure of just how big a disaster the ongoing crisis at the Fukushima Daiichi nuclear facility has become:

Radioactive substances from the crippled Fukushima No. 1 nuclear power plant have now been confirmed in all prefectures, including Uruma, Okinawa Prefecture, about 1,700 kilometers from the plant, according to the science ministry.

The ministry said it concluded the radioactive substances came from the stricken nuclear plant because, in all cases, they contained cesium-134, which has short half-life of two years.

Before the March 11 Great East Japan Earthquake, radioactive substance were barely detectable in most areas.

Or, it could be said, when Fukushima sneezed, all of Japan caught a cold.

And not just Japan, of course. Fallout from Fukushima has drifted halfway around the world. Radioactive isotopes directly linked to Japan’s crippled reactors have been detected in milk and vegetables across the U.S. and Canada. And the Pacific Ocean, too, has been contaminated–and continues to be more so. December brings news of new leaks sending more radioactive runoff from the Japanese reactors into the sea. Tens of thousands of tons of overspill have already flowed into the waters around Japan’s northeastern coast–bringing levels of radioactivity to thousands of times what is considered acceptable–and TEPCO, still nominally the Fukushima’s operator, just had to scrap plans to dump untold tons more after protests from Japanese, Chinese, and Korean fishing concerns. (The contaminated water, still collecting at the plant at a rate of 200 to 500 tons a day, will exceed the facility’s 155,000-ton storage capacity by March.)

The effects of bioaccumulation–as dangerous isotopes move with global tides, and contaminated fish (and their contaminated predators) migrate–presents scientists with a long-term research project where much of the world’s population will serve as unwilling subjects.

And, as has been noted here many times, the crisis is far from over. Even TEPCO’s own conservative (or is that “dishonest?”) models now confirm a core melt-through in reactor 1. TEPCO officials insist that somehow they will cool the surrounding steel or concrete enough to stop the molten corium from going further, but the architect of Fukushima Daiichi Reactor 3, Uehara Haruo, sees things very differently. As relayed by Kevin Kamps of Beyond Nuclear, Haruo says:

It is only a matter of time before the molten core, at least of Unit 1–if not Units 2 and 3–does reach ground water, and if it hits it right. . . you’re going to have a powerful steam explosion.

And, as Kamps explains, that steam explosion will again send massive amounts of radiation into the atmosphere. As longtime nuclear activists Paul Gunter recently put it, “It’s pins and needles time,” implying that while much is unknown about what is going on inside the destroyed reactors, nothing indicates TEPCO is gaining the upper hand on this dire situation.

Yet, with all this–with the spreading fallout, the continuing radioactive water leaks, and the real threat of what so many refer to as a “China Syndrome” event–NRC Chair Jaczko worries that the U.S. nuclear industry has become complacent about the safety gaps highlighted by the Fukushima disaster. Given the evidence–and given that the NRC itself spent all summer studying the crisis and drafting recommendations based on “lessons learned”–it is hard to believe complacency is really the problem. It is probably even too generous to say that the industry suffers from willful ignorance. No, when considering the contagion spreading from Japan and the coughs and hiccups that are practically weekly here in the United States, it is probably more accurate to say that the profit-driven, government-protected nuclear sector is actively callous.

The risks, after all, of the nuclear business model are not borne by power companies. In the U.S., federal loan guarantees, state tax breaks and utility rate hikes insulate nuclear operators from the costs of slipshod construction, poor training, and malign management. Even without that, perhaps the only lesson the domestic nuclear industry will choose to learn from Fukushima is that when a catastrophe like this happens, the government is given no choice but to step in. (Beyond the price of the cleanup, and the healthcare and relocation of those in severely contaminated regions, note how TEPCO’s stock price fell all week after word leaked that the Japanese Government would buy $13 billion worth of new shares.)

So, what’s a chief regulator to do? Given the overwhelming evidence of industry arrogance in the face of real danger, Jaczko could have an “I am Hamlet, Prince of Denmark” moment, seize his birthright, as it were, and actually demand compliance from the industry he has been tasked to oversee–but, judging from his tone in many interviews, and the continuing approvals of new and renewed operating licenses, it seems more like the NRC chief will remain the Hamlet of the first four acts of the play.

WWSD–What Would Sinatra Do? Read through the Esquire piece and see how, despite his froggy throat and foul mood, Sinatra takes control of his world. In the end, as Sinatra drives his Karmann Ghia down a sunny LA street, a pedestrian sees him through the windshield and stares, wondering, “Could it be? Is it?” Sinatra, knowing he has done what needed to be done–and done it well–stares back, as if to confidently say, “Yes, it is.”

Gregory Jaczko would do well to read (or maybe re-read–who knows?) “Frank Sinatra Has a Cold.” Even if his nuclear rat pack won’t learn the lessons of Fukushima, the NRC chairman could learn a thing or two from the Chairman of the Board. Let’s hope Jaczko does so before his cold gets worse–because the possibility of another Fukushima, here in the United States, is nothing to sneeze at.

The Party Line – November 4, 2011: Self-Styled Clean Energy President Embraces Future That’s Dirty, Dangerous, and Expensive

Posted on by

“Reeling from months of protests, President Barack Obama’s advisors are worried. . . .”

So begins a November 3rd story from Reuters assessing the potential political fallout from an administration decision to green-light the Keystone XL pipeline, TransCanada Corp’s plan to move crude oil from the tar sands of Alberta to refineries in Texas. Reading the whole piece, one can’t help but feel that Obama is still of a mind to go ahead and OK this dangerous and much-derided plan, it is just the Obama 2012 campaign that’s agonizing over how to spin it.

Back in 2008, Obama the candidate seemed to understand the threat posed by global warming, and he spoke often of moving away from carbon-heavy fuel sources like tar sands. Now, a good part of what is considered the president’s “base,” it seems, understands that the transcontinental pipeline is not only a danger to farmlands and aquifers, but also a betrayal of a campaign promise.

Don’t think this is the dynamic at play? Look at recent administration boasts about such “green” initiatives as raising the Corporate Average Fuel Economy (CAFE) standards, or just read Obama campaign spokesman Ben LaBolt in the abovementioned Reuters story:

“The president has done more to wean us off of foreign oil and transition the nation to a clean energy economy than any other,” he said. “When Americans compare the president’s record promoting clean energy and America’s energy security to those of the leading Republican candidates, who don’t even believe that climate change is an issue that we need to address and would cede the clean energy market to China, there will be no question about who will continue our progress.”

Moving beyond the observation that this is the same “We suck less” positioning that performed so poorly for Democrats in 2010, there are indeed many questions raised by Obama’s apparent take on our energy future.

LaBolt’s claim, “The president has done more to wean us off of foreign oil and transition the nation to a clean energy economy than any other,” first begs the obvious fact-check: Alberta is not in the US, and tar sands crude is no one’s idea of clean energy. But it is not a big leap to read this statement as something more inclusive, something meant to refer to all of the Obama administration’s moves in the energy sector. Indeed, with references to clean energy, climate change and China, the Obama campaign is probably hoping for some to hear a commitment to solar power, while others might understand it as an embrace of nuclear fission.

Intent notwithstanding, administration moves have underscored the latter–a White House enraptured with nuclear power–just as events continue to lay bare the lie that US nuclear power generation could fit anywhere into a tale of clean, domestic energy advocacy.

A new stupid way to boil water?

On November 1, the Nuclear Regulatory Commission approved a new design of what is called an Advanced Boiling Water Reactor (ABWR) slated for construction in South Texas. The plan to build two 1,350-megawatt reactors was originally pitched five years ago, with the original plant operator, NRG Energy (so nice they named it twice!), requesting design certification for Toshiba’s version of ABWRs in 2007.

But in 2009, the NRC made mandatory what had previously been a voluntary requirement that plants would be able to withstand a 9/11-style aircraft attack and continue to cool the reactor and spent fuel pools. The ABWR design, and its certification, had to be amended. This amended design is what just received the NRC’s thumbs-up.

A funny thing, however, happened since the original request: NRG stopped investing in the project. NRG was the prime investor in the “South Texas Project Nuclear Power Co.,” which is the name of the body that originally submitted the amended design. Without NRG, Toshiba has been shepherding the certification request, the one just approved by the Nuclear Regulatory Commission. Just one hitch, though, foreign companies are not allowed to operate nuclear power plants in the United States–a point that seems to have been missed by the NRC (and by most establishment news reports about the certification).

This design certification without funding or domestic management in place provides an almost comic counterpoint to the funding-without-certification approach taken by the Obama administration for the AP1000 reactors proposed for Georgia’s Plant Vogtle.

The AP1000, a riff on a Pressurized Water Reactor design, is supposed to provide passive cooling inside a reactor in the event of a loss of power to the active cooling system. There are many questions about the AP1000, and it too had to be altered to comply with the 2009 9/11 rules, but the most recent delay in certification comes at least in part from concerns that the design should also account for a Fukushima-like seismic event. At this point, Vogtle’s operator, The Southern Company, and the NRC have not come to a meeting of the minds.

But these concerns–or, at least, delays–did nothing to dampen the enthusiasm of the White House. In February of 2010, without any design certification in place, none other than Barak Obama himself announced $8.33 billion in loan guarantees for Southern. This was done with fanfare at a public event (there’s even a YouTube of the announcement).

So, certification with no funding, or funding with no certification–to the US federal government, it doesn’t matter. And it spells out two points in bold type: The Obama administration stands squarely behind nuclear power. . . and the marketplace does not. Without help from what the campaign would have voters believe is the all-time greatest champion of clean, green, domestic energy, new nuclear reactors would not be built in the United States.

Uranium extraction is not clean and never has been. The US is still paying to clean up from mining in the southwest that ended half a century ago. And today, uranium is not really a domestic fuel source, either. A list of the world’s top uranium producers looks like this: 1) Kazakhstan, 2) Canada, 3) Australia, 4) Namibia, 5) Russia, 6) Niger, 7) Uzbekistan. The US comes in eighth, accounting for just 2.9 percent of the world’s uranium production. By contrast, the US ranks third in global oil production, extracting almost 11 percent of the world’s crude.

And uranium doesn’t jump out of the ground ready to go for a nuclear reactor. The processing of uranium ore into useable fuel is a dirty, costly and energy intensive endeavor requiring loan guarantees, waste storage and safety protocols all its own. (And as if to underscore this, House Speaker John Boehner has recently requested federal loan guarantees to build a new nuclear processing plant in his home state of Ohio.)

Fukushima: a case study

A pair of new stories out of Japan provide all the evidence any president would need to honestly evaluate the role of nuclear power in America’s supposedly clean, green energy future.

Fukushima isn’t a single event, it is an ongoing, ever-evolving, always metastasizing crisis. In case anyone thought otherwise, the detection of radioactive xenon in Fukushima Daiichi reactor 2 provided a chance to again pay heed to just how serious things remain at the crippled Japanese nuclear facility.

Though Tokyo Electric Power Company (TEPCO), the nominal owners Fukushima Daiichi, contend that the trace of xenon gas does not represent evidence of a nuclear chain reaction inside the reactor previously thought closest to a so-called “cold shutdown,” they still pumped in boric acid–a substance used to mitigate nuclear fission.

Tokyo Electric may or may not be telling the whole truth in this instance, but evidence from throughout this disaster dictates skepticism. For example, scientists have again revised upwards their estimates of total radiation released from the plant, and a new study explodes TEPCO’s minimalist fairytale:

France’s l’Institut de Radioprotection et de Surete Nucleaire (Institute for Radiological Protection and Nuclear Safety, or IRSN) has issued a recent report stating that the amount of radioactive cesium-137 that entered the Pacific after 11 March was probably nearly 30 times the amount stated by Tokyo Electric Power Co. in May.

According to IRSN, the amount of the radioactive isotope cesium-137 that flowed into the ocean from the Fukushima Daiichi nuclear plant between March 21 and mid-July reached an estimated 27.1 quadrillion becquerels.

Quadrillion is not a number that often comes up in polite conversation, but suffice it to say, it’s a lot. . . even for becquerels. Soon after the March 11 earthquake, Japan revised acceptable levels of radioactive cesium upward. . . to 500 becquerels per kilogram. Though even the 27.1 quadrillion number sort of redefines the phrase “a drop in the ocean,” the really disturbing notion is that with a relatively long half-life, the pattern of Pacific currents, and the principles of bio-accumulation and bio-concentration at play, it is possible that everyone who includes Pacific Ocean fish in his or her diet is now part of an informal, long-term experiment on the effects of low-level radioactive contamination. Or, as the same story as above snidely puts it:

The radioactive silver lining? Radioactive cesium-137 has a half life of roughly 30 years, so if the IRSN estimates are accurate, then [b]y 2041 the Pacific’s aquatic life will only be subjected to a mere 13.55 quadrillion becquerels of radiation.

But long half-lives and long-term health effects require long-range thinking, not to mention arguments about the relative value of human life. Perhaps another fresh release from Japan tells the nuclear story in numbers a deficit-obsessed DC elite can more easily comprehend:

Tokyo Electric Power Co. won approval for a 900 billion yen ($11.5 billion) bailout from the government after the Fukushima nuclear catastrophe to avert bankruptcy and start paying compensation for the crisis.

Trade and Industry Minister Yukio Edano approved the support after the company known as Tepco committed to cutting 7,400 jobs and 2.5 trillion yen in costs. The utility forecast an annual loss of 600 billion yen, its second since the March earthquake and tsunami wrecked its Fukushima nuclear plant.

Eleven-and-one-half-billion dollars–and that only takes TEPCO through March 2013. Who here thinks the crisis will be over by then? It almost makes Obama’s $8.33 billion loan guarantee to Southern look like a bargain.

Almost.

Except that the loan guarantee is just for construction of a yet unapproved reactor design–should Southern, or whatever entity might eventually operate Plant Vogtle, experience an accident, that would likely be a whole other ball of bailout.

But what could possibly go wrong? Well, as repeatedly documented in this column, a lot. Beyond the level-7 sinkhole that is Fukushima, in the US, 2011 alone has seen manmade accidents and natural disasters that have scrammed and/or damaged more than a half-dozen reactors. And with each event, a process of shutdown, repair, inspection, authorization and startup costs time and money that does nothing to provide America with clean, safe, renewable, affordable energy.

Each event does, however, add costs to a variety of segments of the economy. Energy production and utility bills are obvious, but this nuclear obsession also drives up costs for healthcare, food safety, air and water quality, the yet-to-be-solved problem of long-term waste storage, and don’t forget the additional tax burden required to support all the bailouts, tax breaks and loan guarantees for the nuclear industry. The Center for Strategic and International Studies, a US think tank, has also called for a global study of the health effects of long-term radiation exposure as part of an international response to the Fukushima disaster. That, too, is an expense that should be factored into the real cost of nuclear power.

One thing, however, has gotten cheaper since the Japanese earthquake and tsunami gave the world its third top-level nuclear accident since 1979, and that would be uranium. Since March, world uranium prices have fallen some thirty percent. In fact, demand is so low, the French company Areva has decided to suspend its uranium mining in the Central African Republic–for two years.

The market is again speaking, but to those predisposed to cherish the siren song of nuclear power, cheap uranium could easily become the excuse to dash greener, safer alternative energy development.

Since the earliest days of nuclear power, that siren song has gone something like this: clean, safe, and too cheap to meter. Obviously, 2011 has proven none of that rings true, but when an administration believes it can greenwash away the political fallout from a tar sands pipeline, is it such a stretch to see them ignoring the financial and radioactive fallout of nuclear power in their attempt to package Obama as the cleanest, greenest energy president ever?

I am always happy to see the issues discussed in this column get attention from a broader audience, so I was thrilled to see Rachel Maddow take nine minutes out of her Wednesday show to call attention to what she sees as a scandal no one finds sexy enough to get excited about–namely the dangerous state of nuclear power plants across the US. But her contention that no one is paying attention irks me, at least a little. I have lost count of the number of posts I have devoted to this very subject this year, and I think, throughout, most would say I find much about this subject quite scandalous. So, Rachel, next time you want to talk about this stuff, the next time you want to share your excitement about this scandal, call me.

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.
