Japan’s N-safety problems remain 5 years after Fukushima

Five years ago, a magnitude nine earthquake off the east coast of Japan triggered a tsunami that killed almost 20,000 people and led to meltdowns and release of radioactive material at Japan’s Fukushima Daiichi Nuclear Power Plant. The disaster inflicted nearly half a trillion dollars in economic losses and caused the shutdown of more than 50 nuclear reactors, depriving Japan of 30 percent of its electric power capacity.
I visited Tokyo in June of 2011 on behalf of the Maureen and Mike Mansfield Foundation to convene a Japan-U.S. joint study group on
policy lessons from Fukushima.
At the time, aftershocks had abated, but within the wreckage of Fukushima’s reactor buildings, radiation levels were still 1,000 times above normal, and nuclear materials remained perilously vulnerable. As far away as Tokyo, residents armed with dosimeters located radiological hotspots in neighborhood parks and their own apartment buildings. Electricity rationing left schools, homes, and downtown offices dark and uncomfortably warm. Japanese friends continued to be haunted by “jishin yoi,” the imagined sensation of tremors and swaying. Our study group understood that Japan’s immediate challenge was cleaning up the mess, but large public policy challenges were on the horizon. Among these was confronting the now-obvious risk of nuclear power.
Late last year, we reconvened our group to benchmark Japan’s progress. Japan now has a new Nuclear Regulatory Authority (JNRA) that enjoys insulation from the
influence of nuclear energy stakeholders. JNRA has imposed stricter safety standards, reflecting many of Fukushima’s most important
lessons. Managers of many nuclear facilities have undertaken safety improvements beyond JNRA’s
requirements in a bid for public confidence.
But despite improvements in nuclear safety, problems remain. The quake shattered more than just the seabed east of Tohoku. It also pulverized public confidence in
the government and industry’s
handling of nuclear power. Polls show that a majority of the Japanese people remains deeply anxious about nuclear power. Anti-nuclear energy protesters are camped in the center of Tokyo’s government district, standing vigil reminiscent of the late Concepcion Picciotto, the American anti-nuclear weapons activist who sustained a protest outside the White House for 35 years. Five years after Fukushima, Japan’s power industry remains hobbled, with just two of 52 reactors
Restoring Japanese faith in nuclear power requires more than just establishing a new, tougher regulator. It demands greater leadership from Japanese prime minister Shinzo Abe. Nuclear power is central to Abe’s top priorities: economic revitalization and national security. With Japan’s nuclear plants off line, Japan sharply increased imports of oil and gas. As a result, Japan has seen its first trade deficit in decades. Japan is also more vulnerable to energy supply disruptions caused by political instability, natural disasters, and even currency value fluctuations. Furthermore, Abe’s COP21 climate change goals likely remain out
of reach so long as nuclear plants are off-line.
Abe has shown political courage by calling for nuclear power to remain a significant part (roughly a fifth) of the nation’s energy mix. But his job should not end there. Even as nuclear reactors return to service, Japan has never directly dealt with the question of risk and, after Fukushima, how much risk society is willing to endure. JNRA has set new standards for mitigating risk, but it understandably refuses to be the arbiter of whether Japan’s reactors are “safe enough” to restart. This question lies at the heart of a debate that divides Japanese society like few others, and in failing to resolve this question before restarting nuclear plants, Abe has thrown his regulator into the middle of
that debate. But this is not a regulatory question. It is a public policy question.
The prime minister is not the only elected leader with a role
in Japanese nuclear regulation. Mayors and governors have the ability to hold up nuclear plant restarts if they are not satisfied with the conditions. Japan’s Diet also has a role in overseeing Japan’s nuclear governance, and it has created special committees for this express purpose. But mayors and governors have conflicting interests as nuclear plants provide jobs and tax revenue to their constituents. Diet members find nuclear energy to be politically risky and have made only limited use of their special committees. Both local leaders and Diet offices tend to lack the technical expertise to evaluate
nuclear safety, utility management structure, evacuation arrangements, etc.
No doubt, many of Abe’s advisers are probably counseling him to steer clear of the nuclear energy debate. After all, plants are slowly coming on line without the prime minister having to expend much political capital on the issue. But someone must be accountable for Japan’s nuclear safety, and that leadership is unlikely to come from the JNRA, the Diet, or Japan’s
mayors and governors.
Abe should make clear to the Japanese people where the buck stops on nuclear safety, tell them why it is worth the risk, and put his weight behind strengthening nuclear governance. Until he does so, he leaves a hole at the center of Japan’s regulatory regime and he exposes the country to unnecessary risk of another Fukushima disaster. Abe has a vision for Japan, and in pursuing it he has proven willing to lead on the issues that are important, not just the ones that are popular. The fact that he is now the sixth longest serving prime minister in Japan’s post-war history suggests that Japan appreciates him for it. Nuclear energy is not popular, but it is important. Right now it needs Abe’s leadership.
