Japan’s Nuclear Disaster and the Politics of Safety Governance


Florentine Koppenborg, Technical University of Munich

The regulatory reforms taken up in the wake of the Fukushima disaster on March 11, 2011, directly and indirectly raised the costs of nuclear power in Japan. The independent Nuclear Regulation Authority resisted capture by the nuclear industry and fundamentally altered the environment for nuclear policy implementation. Independent safety regulation changed state-business relations in the nuclear power domain from regulatory capture to top-down safety regulation, which raised technical safety costs for electric utilities. Furthermore, the safety agency’s extended emergency preparedness regulations expanded the allegorical backyard of NIMBY demonstrations. Antinuclear protests, mainly lawsuits challenging restarts, incurred additional social acceptance costs. Increasing costs undermined pronuclear actors’ ability to implement nuclear power policy and caused a rift inside the “nuclear village.” Small nuclear safety administration reforms were, in fact, game changers for nuclear power politics in Japan.
