Fukushima Daiichi Nuclear Power Plant Photos 14

This Feb. 2011 aerial photo shows Hamaoka nuclear power plant of Chubu Electric Power Co., in Omaezaki city, Shizuoka prefecture, central Japan. Prime Minister Naoto Kan told a news conference Friday, May 6, 2011, his government asked operator Chubu Electric Power Co. to suspend two running reactors and a third shut for a regular inspection at its Hamaoka nuclear plant, because of safety concerns in the event of a major earthquake.

A full-scale mockup of No.3 reactor of Chubu Electric Power's Hamaoka Nuclear Power Station, which is the same model of boiling-water reactor (BWR) of the Tokyo Electric Power Co.'s (TEPCO) crippled Fukushima Daiichi Nuclear Power Plant, is displayed at a nuclear museum beside the Hamaoka station in Omaezaki, Shizuoka Prefecture, about 200 km (124 miles) southwest of Tokyo, May 5, 2011. Workers entered the No.1 reactor building at Japan's crippled Fukushima Daiichi nuclear plant on Thursday for the first time since a hydrogen explosion ripped its roof off a day after the devastating March earthquake and tsunami.

Electricity Generating Authority of Thailand (EGAT) officials remove a diesel electric generator at Nong Jok power plant in Bangkok April 27, 2011, before preparing it to be shipped to Japan. Tokyo Electric Power Co (TEPCO) requested last month to borrow Thailand's power generators for at least 3-5 years to ease Japan's power shortage caused by devastation from March 11's earthquake and tsunami. Thailand will send Japan two generators, each with capacities of 122 megawatts. The first generator is slated to be shipped May 9, and the second May 15, and both generators are likely to be fully operations in Japan in August.
