The is a large, modern (housing the world's first ABWR) nuclear power plant on a 4.2-square-kilometer (1,038 acres) site〔TEPCO Official Press Release (Japanese). (First in Japan - Use of the Full Area for Power Plant Buildings, Reinforced Concrete R&D, and Waste Incinerator Building ). July 25, 2002.〕 including land in the towns of Kashiwazaki and Kariwa in Niigata Prefecture, Japan on the coast of the Sea of Japan, from where it gets cooling water. The plant is owned and operated by Tokyo Electric Power Company (TEPCO). It was the largest nuclear generating station in the world by net electrical power rating. It was approximately from the epicenter of the second strongest earthquake to ever occur at a nuclear plant, the Mw 6.6 July 2007 Chūetsu offshore earthquake. This shook the plant beyond design basis and initiated an extended shutdown for inspection, which indicated that greater earthquake-proofing was needed before operation could be resumed. The plant was completely shut down for 21 months following the earthquake. Unit 7 was restarted after seismic upgrades on May 9, 2009, followed later by units 1, 5, and 6. (Units 2, 3, 4 were not restarted). After the April 2011 earthquake, all restarted units were shut down and safety improvements are being carried out. no units are restarted and no units are expected to restart sooner than the end of 2015.〔(Japan Times: TEPCO may ask U.S. utility to inspect Kashiwazaki-Kariwa nuclear plant )〕 ==Reactors== There are seven units, which are all lined up along the coast line. Numbering starts at Unit 1 with the south-most unit through Unit 4, then there is a large green space in between Unit 4 and 7, then it continues with Units 6 and 5, the newest of the reactors.〔(Monitoring )>〕 The power installation costs for units at this site well reflect the general trend in costs of nuclear plants. Capital costs increased through the 1980s but have become cheaper in modern times. The last two units were the first Advanced Boiling Water Reactors (ABWRs) ever built. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Kashiwazaki-Kariwa Nuclear Power Plant」の詳細全文を読む スポンサード リンク
