Grand Gulf Nuclear Station has one sixth generation General Electric boiling water reactor. It lies on a site near Port Gibson, Mississippi. The site is wooded and contains two lakes. The plant has a 520-foot natural draft cooling tower. Grand Gulf's reactor is the most powerful in the United States, with a core power of 4408 MWth yielding a nominal gross electrical output of about 1500 MWe. Grand Gulf is operated by Entergy, which also owns 90% of the station through their subsidiary, System Energy Resources Inc. The other 10% is owned by South Mississippi Electric Power Association. == Units 2 and 3 == Adjacent to the operating Grand Gulf station, is an unfinished concrete structure that was to be the containment for Unit 2, a twin to the existing Unit 1. In December 1979, staggered by construction cost, Entergy (then called Middle South Utilities) stopped work on Unit 2. On September 22, 2005, it was announced that Grand Gulf had been selected as the site for a GE ESBWR reactor. For details, see Nuclear Power 2010 Program. This was to be Unit 3. In 2007, the U.S. Nuclear Regulatory Commission (NRC) issued an Early Site Permit (ESP) to Grand Gulf. In 2008, Entergy and NuStart submitted a Combined Construction and Operating License (COL) application for a potential new nuclear unit at the Grand Gulf. On January 9, 2009, Entergy indefinitely postponed work towards the license and construction of Unit 3. In September 2015 the NRC withdrew the COL for the ESBWR unit, at the request of Entergy. 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「Grand Gulf Nuclear Generating Station」の詳細全文を読む スポンサード リンク
