New Fukushima Video Shows Disorganized Response, Organized Deception

Posted on by

A frame from early in the newly released Fukushima video.

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

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

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

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

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

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

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

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

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

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

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

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

. . . .

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

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

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

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

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

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

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

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

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

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

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

Fukushima Nuclear Disaster “Man-Made” Reports Japanese Panel; Quake Damaged Plant Before Tsunami

Posted on by

The massive disaster at the Fukushima Daiichi nuclear facility that began with the March 11, 2011 Tohoku earthquake and tsunami could have been prevented and was likely made worse by the response of government officials and plant owners, so says a lengthy report released today by the Japanese Diet (their parliament).

The official report of The Fukushima Nuclear Accident Independent Investigation Committee [PDF] harshly criticizes the Japanese nuclear industry for avoiding safety upgrades and disaster plans that could have mitigated much of what went wrong after a massive quake struck the northeast of Japan last year. The account also includes direct evidence that Japanese regulatory agencies conspired with TEPCO (Fukushima’s owner-operator) to help them forestall improvements and evade scrutiny:

The TEPCO Fukushima Nuclear Power Plant accident was the result of collusion between the government, the regulators and TEPCO, and the lack of governance by said parties. They effectively betrayed the nation’s right to be safe from nuclear accidents.

. . . .

We found evidence that the regulatory agencies would explicitly ask about the operators’ intentions whenever a new regulation was to be implemented. For example, NISA informed the operators that they did not need to consider a possible station blackout (SBO) because the probability was small and other measures were in place. It then asked the operators to write a report that would give the appropriate rationale for why this consideration was unnecessary.

The report also pointed to Japanese cultural conventions, namely the reluctance to question authority–a common refrain in many post-Fukushima analyses.

But perhaps most damning, and most important to the future of Japan and to the future of nuclear power worldwide, is the Investigation’s finding that parts of the containment and cooling systems at Fukushima Daiichi were almost certainly damaged by the earthquake before the mammoth tsunami caused additional destruction:

We conclude that TEPCO was too quick to cite the tsunami as the cause of the nuclear accident and deny that the earthquake caused any damage.

. . . .

[I]t is impossible to limit the direct cause of the accident to the tsunami without substantive evidence. The Commission believes that this is an attempt to avoid responsibility by putting all the blame on the unexpected (the tsunami), as they wrote in their midterm report, and not on the more foreseeable earthquake.

Through our investigation, we have verified that the people involved were aware of the risk from both earthquakes and tsunami. Further, the damage to Unit 1 was caused not only by the tsunami but also by the earthquake, a conclusion made after considering the facts that: 1) the largest tremor hit after the automatic shutdown (SCRAM); 2) JNES confirmed the possibility of a small-scale LOCA (loss of coolant accident); 3) the Unit 1 operators were concerned about leakage of coolant from the valve, and 4) the safety relief valve (SR) was not operating.

Additionally, there were two causes for the loss of external power, both earthquake-related: there was no diversity or independence in the earthquake-resistant external power systems, and the Shin-Fukushima transformer station was not earthquake resistant.

As has been discussed here many times, the nuclear industry and its boosters in government like to point to the “who could have possibly imagined,” “one-two punch” scenario of quake and tsunami to both vouch for the safety of other nuclear facilities and counter any call for reexamination and upgrades of existing safety systems. Fukushima, however, has always proved the catastrophic case study that actually countered this argument–and now there is an exhaustive study to buttress the point.

First, both the quake and the tsunami were far from unpredictable. The chances of each–as well as the magnitude–were very much part of predictions made by scientists and government bureaucrats. There is documentation that Japanese regulators knew and informed their nuclear industry of these potential disasters, but then looked the other way or actively aided the cause as plant operators consistently avoided improving structures, safety systems and accident protocols.

Second, even if there had not been a tsunami, Fukushima Daiichi would have still been a disaster. While the crisis was no doubt exacerbated by the loss of the diesel generators and the influx of seawater, the evidence continues to mount that reactor containment was breached and cooling systems were damaged by the earthquake first. Further, it was the earthquake that damaged all the electrical systems and backups aside from the diesel generators, and there is no guarantee that all generators would have worked flawlessly for their projected life-spans, that the other external and internal power systems could have been restored quickly, or that enough additional portable power could have been trucked in to the facility in time to prevent further damage. In fact, much points to less than optimal resolution of all of these problems.

To repeat, there was loss of external power, loss of coolant, containment breach, and release of radiation after the quake, but before the tsunami hit the Fukushima nuclear plant.

And now for the bad news. . . .

And yet, as harsh as this new report is (and it is even more critical than was expected, which is actually saying something), on first reading, it still appears to pull a punch.

Though the failure of the nuclear reactors and their safety systems is now even further documented in this report, its focus on industry obstruction and government collusion continues in some ways to perpetuate the “culture of safety” myth. By labeling the Fukushima disaster as “Made in Japan,” “manmade” and “preventable,” the panel–as we are fond of saying here–assumes a can opener. By talking up all that government and industry did wrong in advance of March 11, 2011, by critiquing all the lies and crossed signals after the earthquake and tsunami, and by recommending new protocols and upgrades, the Japanese report fiats a best-case scenario for a technology that has consistently proven that no such perfect plan exists.

The facts were all there before 3/11/11, and all the revelations since just add to the atomic pile. Nuclear fission is a process that has to go flawlessly to consistently provide safe and economical electrical power–but the process is too complex, and relies on too many parts, too many people and too volatile a fuel for that to ever really happen. Add in the costs and hazards of uranium mining, transport, fuel milling, and waste storage, and nuclear again proves itself to be dirty, dangerous, and disgustingly expensive.

* * *

And, as if to put an exclamation point at the end of the Diet’s report (and this column), the Japanese government moved this week to restart the nuclear plant at Oi, bringing the No. 3 reactor online just hours before the release of the new Fukushima findings. The Oi facility rests on a fault line, and seismologists, nuclear experts and activists have warned that this facility is at risk much in the way Fukushima Daiichi proved to be.

Most of Japan’s reactors were taken offline following the Tohoku quake, with the last of them–the Oi plant–shut down earlier this year. In the wake of the disaster, Japan’s then-Prime Minister, Naoto Kan, suggested that it might be time for his country to turn away from nuclear power. Demonstrators across Japan seemed to agree and urged Kansai Electric Power Company and current Prime Minister Yoshihiko Noda to delay the restart of Oi. But the government seemed to be hurrying to get Oi back up, despite many questions and several technical glitches.

Noda insists the rush is because of the need for electricity during the hot summer months, but Japan managed surprisingly well last summer (when more of the country’s infrastructure was still damaged from the quake and tsunami) with better conservation and efficiency measures. Perhaps release of this new report provides a more plausible explanation for the apparent urgency.

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

Posted on by

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

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

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

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

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

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

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

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

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

Posted on by

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The Party Line – August 5, 2011: Japan Worries About More Radiation, US Officials Worry About Red Tape

Posted on by

News this week out of Japan that workers at the crippled Fukushima Daiichi nuclear plant have detected extremely high levels of radiation in and around reactor 1. The first incident, on August 1, pinned the Geiger counter at 10 sieverts (1000 rem)—yes, that’s as high as the device could measure, so that number is a minimum—and was taken at the base of a ventilation stack. The second reading, the following day, clocked in at five sieverts per hour inside the reactor building.

I have yet to read an explanation for the discovery of the second reading, but the initial, sky-high measurement on Monday has me and many others scratching heads. A thousand rem is not some little ho-hum number. A half-hour of exposure at that level is fatal in a matter of days, I am told. Where did that radiation come from? When did contamination occur? How is it that such a dangerous level could go unreported for what is now over 140 days?

Officials from the Japanese power company, TEPCO, who have been repeatedly criticized for withholding critical information, insist that contamination likely happened in the first few days of the disaster when workers tried to vent hydrogen from the reactor building in a futile attempt to prevent an explosion. Somehow, though, this part of the facility (which, it should be noted, has been extensively mapped for radioactive hotspots over the last several months) was not measured till August.

Others, such as Arnie Gundersen, chief engineer at Fairwinds Associates, believes levels this high would not have gone undetected this long, and that these new readings represent a recent accumulation. Because the measurement was taken at the base of a ventilation stack that has continued to vent undisclosed amounts from the damaged reactors, Gundersen believes that condensation and radioactive cesium trickled down to the base of the stack—which means that some amount of radioactive isotopes continues to be vented into the atmosphere. And it seems, some not inconsequential amount.

Back in April, TEPCO was ordered to give an accounting of the amounts of radiation released during the crisis, and TEPCO promised to do so by August. It is now August, but there is no sign yet of this report or an indication of when it will be released.

And, just to wrap up newish news from Japan, the government has announced plans to build a wall around Daiichi reaching 60 feet below ground to try to stop contaminated groundwater from reaching the sea. Beef contaminated with radioactive cesium from the plant has turned up in more markets across Japan, and the government has banned the sale of most beef from the north.

Japanese Prime Minister Naoto Kan has fired three government officials with ties to the crisis, including the leader of the Nuclear and Industrial Safety Agency, which would be roughly the Japanese equivalent of the US NRC. Officially, the reason is because the agency did a lousy job of preparing for a tsunami and its disastrous effects, but it also recently came to light that this official had planted pro-nuclear-industry shills at town hall meetings in an attempt to steer public opinion.

Back in the United States, one can only imagine what that kind of accountability would look like—but why imagine, when we have the videotape!

On August 2, when most eyes (like, you know, everyone’s) were on the floor of the Senate, a few of us (probably a very few, it wasn’t even on CSPAN-3) were watching the Senate Committee on Environment and Public Works full committee and subcommittee on Clean Air and Nuclear Safety joint hearing entitled “Review of the NRC’s Near-Term Task Force Recommendations for Enhancing Reactor Safety in the 21st Century.” (Sounds so much more important when you spell it all out.)

This was the hearing on the report I discussed three weeks ago, and besides the obvious observation that there’s 150 minutes of life I’ll never get back, there were a few points worth mentioning.

First, it was clear from the opening statements that no Senator (perhaps with the exception of Bernie Sanders. . . perhaps) was going to come close to making a call for a shift away from nuclear power in the US the way leaders in Germany and Japan have in the wake of the Fukushima disaster. In fact, the tone was very much about moving forward with some version of a flourishing nuclear industry.

For Republicans on the panel, the response was predictable. The only thing that is keeping us from rushing headlong into a glorious future with upwards of 100 fabulous, new nuclear plants is excessive government regulation. In fact, Senators Lamar Alexander and Jeff Sessions seemed stunned that the Nuclear Regulatory Commission had the primary responsibility of protecting the health and safety of the public rather than helping to foster an environment favorable to the expansion of the nuclear industry. (A funny protest, really, considering that the NRC has long been criticized for acting as a booster club for the industry it is supposed to regulate—and especially risible in light of this summer’s AP exposé on the cozy relationship between power companies and regulators.) The GOP contingent chastised NRC members for thinking of themselves as guardians of public safety without regard to what it would cost what they always euphemistically referred to as “stakeholders” (as did the more overtly pro-industry commissioners).

This, in turn, earned the senators a chastisement of their own from EPW chair, Sen. Barbara Boxer, who literally threw the book at them. . . ok, she didn’t throw the book, she just read from the law that empowers the NRC.

Indeed, Boxer had a more refreshing take on government regulation. The California Democrat said that if the industry wanted to operate and expand, it had to demonstrate that it could do so safely. Boxer stressed that it was important that citizens saw regulators as their defenders, able to act quickly in response to a crisis and honestly assure the safety of nuclear facilities. It takes a trusted regulatory regime for an industry to prosper.

That is a fair point, and one that applies to a much broader discourse about government regulation. Alas, in this case, it papers over a slow, lax regulatory history and a nuclear industry that has done a solid job of dumping campaign cash into the coffers of most of the politicians responsible for oversight.

On the always amusing “did he just say that?” front, there was Sen. Alexander saying that we didn’t have to worry about anything like what happened in Japan because we had a different system, blithely adding that no one had ever been killed by an accident at a US nuclear plant or on a US nuclear submarine. This will be news to the families of the four workers killed in two separate accidents at Surry 2 in Virginia, or to the crews of the USS Thresher and USS Scorpion. Or to the one man killed in the 1959 Navy reactor explosion. (Nitpickers will argue, of course. Lucky for them, the four dead at Surry 2 died from steam burns before they had to worry about radiation, and the two subs imploded after plummeting below their crush depth, and so cannot be classified with surety as “nuclear” accidents. The 1959 USS Triton accident happened on a prototype at a Navy training center, so I guess that won’t count, either.)

And, of course, Alexander has no room in his worldview for the 430 infants (PDF) (the most conservative estimate) that died from radiation released during the Three Mile Island disaster.

Jeff Sessions is a circus sideshow all by himself (an imperious, ignorant sideshow). He used most of his time to criticize Gregory Jaczko, Chair of the Nuclear Regulatory Commission, for assuming emergency powers in the days after the earthquake and tsunami that crippled Fukushima Daiichi. In essence, Sessions was upset that Jaczko empanelled the task force quickly, rather than allow the process to be sabotaged by commissioners more friendly with those aforementioned stakeholders.

Sessions also used the story of how the Japanese are pulling together to conserve energy now that so many of its nuclear power plants are offline to negatively paint the dystopian hellscape that awaits the US if we were to shift away from nuclear power. Conservation, including the royal family using flashlights in their garden, lord save us! (This New Yorker had to laugh when Sessions told of the horrors of Japanese subway platforms that now went un-air-conditioned for three hours a day.)

The senator also tossed out that nuclear was a clean, safe and cheap domestic source of energy. None of those things are true, of course. Mining and refining the fissile materials for the reactors is polluting and comes with a large carbon footprint. We still have no clear plan to deal with “spent” fuel. Fukushima, TMI, Chernobyl, and dozens of less famous disasters belie the “safe” assumption. As far as “cheap,” when you add in the government subsidies, loan guarantees, tax breaks, security costs, and the need for a fuel -disposal infrastructure, nuclear power is not just not “cheap,” it is one of the most expensive options out there. And, as for “domestic,” as I have detailed before, we import most of our uranium—and not always from the nicest people.

Alas, no one had the inclination in this Senate session to respond with any of that to Sen. Sessions. The real problems facing our nuclear future were not really on the table this week.

What the two-and-a-half hour hearing really boiled down to, really hinged on, was that NRC Chair Jaczko believes that 90 days is plenty of time for disposal of the recommendations (that’s how he put it—we are not talking implementation here, just the decision that the task force recommendations should be turned into rules. . . which would then take about five years to enact), but three of the five-member NRC do not. Those commissioners and their Republican brethren on the committee steadfastly refused to commit to any timeframe on anything, insisting that they needed first to hear from “stakeholders” (yes, that word again).

Democrats for the most part tried to buttress Jaczko, asking for commissioners to at least admit that some of the recommendations could be disposed in 90 days. The results of that request were inconclusive. Boxer, to her credit, vowed to hold hearings every 90 days to push for action on the task force report. (Will any more people be paying attention in November. . . right before Thanksgiving. . . when the SuperCommittee is supposed to deliver its budget-cutting plan? No breaths were held in the crafting of this question.)

But I feel funny rallying around this flag. As I mentioned when the Near-Term Task Force report came out, there is nothing I can see particularly wrong with any of the recommendations, as far as they go, but they fail to address any of the bigger issues, from used fuel disposal to the decommissioning of old, poorly designed, geographically vulnerable facilities. Yes, the NRC should prove that it can act—authoritatively and quickly—in the wake of a disaster. And, the federal government should prove it can rise above campaign considerations to exercise real oversight. But until people like the Senators on the EPW committee, or members of the House Energy and Commerce Committee, or the president, face up to the dangers of nuclear power revealed (again) by the Japanese disaster, or confront the myths of an energy source once called “clean, safe, too cheap to meter,” then hearings like this will feel more like redecorating than real policy.

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.

The Party Line – June 3, 2011: A Tale of Two Countries

Posted on by

It isn’t the best of times; how can we keep it from being the worst of times?

In one country, a government that campaigned on a move to green energy reacts to the nuclear crisis in Japan by reaffirming its commitment to nuclear power. In another country, a government that, only nine months ago, endorsed a plan to expand its reliance on nuclear power reacts to the Fukushima disaster by vowing to shut down all domestic nuclear reactors by 2022, and invest in conservation and alternative energy.

The latter of the two examples is, at present, actually the one more dependent on nuclear power for its domestic electricity production, so what can explain its more populist response to current events?

The first country is, of course, the USA, where the federal government is the product of a “first past the post,” two-party electoral system. The second country is Germany, which chooses its national government by a multi-party, mixed member proportional representation system.

In Germany, the government of Chancellor Angela Merkel is reacting as much—or more—to domestic political pressure as it is to the disaster in Japan. . . and that is not at all a bad thing. Because, in Germany, not only is the government showing a reasonable reaction to a global catastrophe, not only is it changing policy to more accurately reflect the desires of the German people, the government has made a move that looks like it will boost the German economy.

The value of German alternative energy companies instantly shot up after Chancellor Merkel moved early in the week to shift her country away from nuclear power and toward renewable resources. Whereas, in the US, once-promised government investment in a green energy revolution has fallen victim to Beltway deficit hysteria.

This contrast threatens to leave he United States off the leading edge of a technological revolution for the second time this century.

Because of the anti-science policies and hot-button politics of the George W. Bush administration, the US has, to a large extent, missed out on the economic benefits of the genetic engineering revolution. Other countries have made themselves much more hospitable to the research and investment necessary to capitalize on those breakthroughs. And now, the pro-nuclear, pro-coal, Big-Oil-coddling posture of the current Congress and the Obama administration—combined with the cuts to alternative energy programs—threaten to again leave America behind.

A green energy revolution could provide more than “green shoots,” it could be an economic engine equal to, or even greater than, the information revolution that propelled growth in the 1990s. At a time when the US is mired in the worst economic slump since the Great Depression, this is an opportunity it cannot afford to miss. And yet, without an effective group or mechanism available to pressure the people in power, a miss is looking more and more likely.

As it now stands, Germany has a chance to capitalize on a disaster, while the United States looks likely to lose another decade. For Germany, a shot at wisdom. For the US, continued foolishness.
