Effects
Nuclear power plants
Onagawa Nuclear Power Plant, Fukushima I, Fukushima II and Tōkai nuclear power stations were automatically shut down following the earthquake. Higashidōri, also on the northeast coast, was already shut down for a periodic inspection. However, cooling is needed to remove decay heat for several days even when a plant has been shut down. The cooling process is powered by emergency diesel generators, as in the case of Rokkasho nuclear reprocessing plant. At Fukushima I and II emergency power systems failed, leading to severe problems including two large explosions at Fukushima I and leakage of radiation. Over 200,000 people have been evacuated.
