Fukushima I Nuclear Power Plant

The Fukushima I Nuclear Power Plant (福島第一原子力発 電所, Fukushima dai-ichi genshiryoku hatsudensho^?, Fukushima I NPP, 1F), often referred to as Fukushima Dai-ichi, is a nuclear power plant located in the town of Okuma in the Futaba District of Fukushima Prefecture. With six separate units located on site with a combined power of 4.7 GW, Fukushima I is one of the 25 largest nuclear power stations in the world. Fukushima I is the first nuclear plant to be constructed and run entirely by the Tokyo Electric Power Company (TEPCO).
In March 2011, in the immediate wake of the Sendai earthquake and tsunami, the Japanese government declared an “atomic power emergency” and evacuated thousands of residents living close to Fukushima I. Ryohei Shiomi of Japan's nuclear safety commission said that officials are concerned about the possibility of a meltdown.^[1]
