The situation at the Fukushima Daiichi nuclear power plant in Japan remains serious, regardless of the issue getting less press attention. There have been a number of earthquakes since the 11 March earthquake and tsunami, with other nuclear power plants in Japan losing off-site electrical power, at least temporarily. Off-site power availability is imperative in order to maintain nuclear reactors cool, even after shutdown. Onagawa nuclear power plant lost two out of the three power lines supplying off-site power following the 7 April earthquake. All of its reactors have been in cold shutdown since the 11 March earthquake.
The Fukushima Daiichi accident is now at a provisional level 7 on INES. This rating considers the accidents at reactors 1, 2 and 3 as a single event on INES and uses an estimated total release to the atmosphere as a justification. The only other known nuclear accident rated at this level is the Chernobyl disaster. NISA estimates that the release of radioactive material into the atmosphere amounts to approximately 10% of the Chernobyl accident. New evacuation areas beyond the 20 km radius from the Fukushima Daiichi power plant have been established on 11 April.
