Masao Yoshida – the former plant manager of the Fukushima nuclear power plant during the time when it was hit by the Great East Japan Earthquake and tsunami in March 2011 – died of cancer last year, but his recorded testimony revealed a flaw in the disaster management process that probably caused the chaos around the way Tokyo Electric Power Co. (TEPCO) dealt with the disaster at that time. According to Yoshida’s testimony, the safety inspectors were among the first to flee the site at the time of the disaster.
The safety inspectors were under the Nuclear Industrial Safety Agency (NISA), the predecessor of the Nuclear Regulation Authority (NRA), and they were supposed to remain on site to be able to give a factual and solid assessment of what needed to be done to deal with the accident and the multiple reactor meltdowns. As such, with the lack of safety inspectors onsite, the Japanese government was forced to rely on sometimes erroneous and mostly chaotic information from TEPCO. Then-Prime Minister Naoto Kan had gone to TEPCO’s Tokyo office, ultimately leading to the decision that a base of communications for the disaster was set up by TEPCO and the Japanese government in Tokyo, 230 kilometers away from where the disaster was taking place. That in itself was a hindrance to the proper flow of information and the correct assessment of the disaster.
Because of this testimony, a review of the government’s nuclear disaster manual took place. The NRA is now obligated to stay in an emergency command center within the vicinity of any nuclear power plant that has trouble to assess the situation and gather information. The government is also obliged to activate Japan’s Self-Defense Force (SDF) and other such agencies that could help in the disaster.
