“Though global safety standards kept on improving, we wasted our time coming up with excuses for why Japan didn't need to bother meeting them.” Madarame Haruki, Chairman, Nuclear Safety Commission, Diet testimony, 2/15/12
The nuclear accident at Fukushima was precipitated by natural disaster, but poor risk management, including a failure to comprehend tectonic risk in the most earthquake prone country in the world, and an institutionalized complacency about risk, were major factors increasing the likelihood of a major accident and fumbling crisis response. Tokyo Electric Power Company (TEPCO), the utility operating the Fukushima Daiichi Plant, and the Nuclear and Industrial Safety Agency (NISA), the government regulatory authority, mismanaged a range of risks - siting, seismic, tsunami, emergency preparedness and radiation - and it is this mismanagement that made Fukushima into Japan's Chernobyl. Investigations into the accident have established that the crisis response was improvised and inadequate because of lack of preparation, institutional flaws in emergency procedures, and poor communication within the government and between officials and TEPCO.
