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.

Fukushima Plus Two: Still the Beginning?

An IAEA inspector examines the remains of reactor 3 at Fukushima Daiichi (5/27/11)

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

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

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

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

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