Fukushima Two Years Later: Many Questions, One Clear Answer

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.

End-of-Summer News Puts Nuclear Renaissance on Permanent Vacation

The Nuclear Regulatory Commission cannot issue a license for the construction and operation of a new nuclear reactor in Maryland–that is the ruling of the NRC’s Atomic Safety and Licensing Board (ASLB) handed down Thursday.

In their decision, the ASLB agreed with intervenors that the Calvert Cliffs 3 reactor project planned for the shores of Chesapeake Bay violated the Atomic Energy Act’s prohibition against “foreign ownership, control, or domination.” UniStar, the parent company for the proposal, is wholly owned by French energy giant Électricité de France (EDF).

EDF had originally partnered with Constellation Energy, the operator of two existing Calvert Cliffs reactors, but Constellation pulled out of the project in 2010. At the time, Constellation balked at government requirements that Constellation put $880 million down on a federal loan guarantee of $7.6 billion (about 12 percent). Constellation wanted to risk no more than one or two percent of their own capital, terms the feds were then willing to meet if Constellation and EDF could guarantee the plant’s completion. Constellation also found that requirement too onerous.

Constellation has since been purchased by Exelon.

The ASLB decision technically gives EDF 60 days to find a new American partner, but given the history and the current state of the energy market, new suitors seem highly unlikely. It marks only the second time a license has been denied by the ASLB. (The first, for the Byron, Illinois plant in 1984 was overturned on appeal. Byron opened the next year, and Illinois’s groundwater has never been the same.) The NRC also declined to grant a license to the South Texas Project late last year when US-based NRG Energy (corporate ID courtesy of the Department of Redundancy Department) pulled out of the project, leaving Japanese-owned Toshiba as the only stakeholder.

The Calvert Cliffs intervenors were led by the Nuclear Information and Resource Service (NIRS), which has been fighting Calvert Cliffs 3 almost since its inception. NIRS was joined by Beyond Nuclear, Public Citizen and Southern Maryland CARES.

Michael Mariotte, Executive director of NIRS, called Thursday’s decision “a blow to the so-called ‘nuclear renaissance,’” noting that back in 2007, when permit requests were submitted for Calvert Cliffs 3, the project was considered the “flagship” of a coming fleet of new reactors. “Now,” said Mariotte, “it is a symbol for the deservedly failed revival of nuclear power in the US.”

A symbol, yes, but far from the only symbol. Read the rest of this entry →

Fukushima One Year On: Many Revelations, Few Surprises

11:30 am in Uncategorized by Gregg Levine

One year on, perhaps the most surprising thing about the Fukushima crisis is that nothing is really that surprising. Almost every problem encountered was at some point foreseen, almost everything that went wrong was previously discussed, and almost every system that failed was predicted to fail, sometimes decades earlier. Not all by one person, obviously, not all at one time or in one place, but if there is anything to be gleaned from sorting through the multiple reports now being released to commemorate the first anniversary of the Tohoku earthquake and tsunami–and the start of the crisis at Fukushima Daiichi–it is that, while there is much still to be learned, we already know what is to be done. . . because we knew it all before the disaster began.

This is not to say that any one person–any plant manager, nuclear worker, TEPCO executive, or government official–had all that knowledge on hand or had all the guaranteed right answers when each moment of decision arose. We know that because the various timelines and reconstructions now make it clear that several individual mistakes were made in the minutes, hours and days following the dual natural disasters. Instead, the analysis a year out teaches us that any honest examination of the history of nuclear power, and any responsible engagement of the numerous red flags and warnings would have taken the Fukushima disasters (yes, plural) out of the realm of “if,” and placed it squarely into the category of “when.”

Following closely the release of findings by the Rebuild Japan Foundation and a report from the Union of Concerned Scientists (both discussed here in recent weeks), a new paper, “Fukushima in review: A complex disaster, a disastrous response,” written by two members of the Rebuild Japan Foundation for the Bulletin of the Atomic Scientists, provides a detailed and disturbing window on a long list of failures that exacerbated the problems at Japan’s crippled Fukushima Daiichi facility. Among them, they include misinterpreting on-site observations, the lack of applicable protocols, inadequate industry guidelines, and the absence of both a definitive chain of command and the physical presence of the supposed commanders. But first and foremost, existing at the core of the crisis that has seen three reactor meltdowns, numerous explosions, radioactive contamination of land, air and sea, and the mass and perhaps permanent evacuation of tens of thousands of residents from a 20 kilometer exclusion zone, is what the Bulletin paper calls “The trap of the absolute safety myth”: Read the rest of this entry →

Union of Concerned Scientists Report: Nuclear “Near Misses” Symptom of Failing Regulatory Regime

8:59 am in Uncategorized by Gregg Levine

In its second annual report on the safety of nuclear power facilities (PDF) in the United States, the Union of Concerned Scientists have documented 15 troubling lapses–what they call “near misses”–at 13 of the nation’s atomic plants. The study details specific problems that still want for repairs, but much more disturbing, it also outlines systemic flaws in America’s nuclear regulation and oversight regime.

The problems range from aging and improperly maintained safety systems to unforgivably long delays in the implementation of Nuclear Regulatory Commission rules on fire suppression and seismic security:

We found that the NRC is allowing 47 reactors to operate despite known violations of fire-protection regulations dating back to 1980. The NRC is also allowing 27 reactors to operate even though their safety systems are not designed to protect them from earthquake-related hazards identified in 1996. Eight reactors suffer from both afflictions. The NRC established safety regulations to protect Americans from the inherent hazards of nuclear power plants. However, it is simply not fulfilling its mandate when it allows numerous plant owners to violate safety regulations for long periods of time.

The report also notes instances where nuclear workers were needlessly exposed to unsafe levels of radiation, and plants where failure to follow basic protocols had rendered backup systems functionally useless.

But perhaps most alarming (if not actually surprising) were the UCS findings on how the NRC handled Component Design Bases Inspections, or CDBIs:

Inspectors are supposed to use CDBIs to determine whether owners are operating and maintaining their reactors within specifications approved during design and licensing. Some of the problems concerned containment vent valves, battery power sources, and emergency diesel generators—components that affected the severity of the disaster at the Fukushima Dai-Ichi nuclear plant in Japan.

While it was good that the NRC identified these problems, each CDBI audits only a very small sample of possible trouble spots. For example, the CDBI at the Harris nuclear plant in North Carolina examined just 31 safety-related items among literally thousands of candidates. That audit found 10 problems. Beyond ensuring that the plant’s owner corrected those 10 problems, the NRC should have insisted that it identify and correct inadequacies in the plant’s testing and inspection regimes that allowed these problems to exist undetected in the first place. The true value of the CDBIs stems from the weaknesses they reveal in the owners’ testing and inspection regimes. But that value is realized only when the NRC forces owners to remedy those weaknesses.

In other words, it’s nice that you made the good folks at Harris fix those problems, but when a preliminary audit reveals a one-third failure rate, perhaps that plant has earned itself a full top-to-bottom inspection. Read the rest of this entry →
