Loviisa Nuclear Power Plant (NPP) ((フィンランド語:Loviisan ydinvoimalaitos), (スウェーデン語:Lovisa kärnkraftverk),), is a nuclear power plant located close to the Finnish city of Loviisa. It houses two Soviet-designed VVER-440/213 PWR reactors, each with a capacity of 510 MW. The reactors at Loviisa NPP went into commercial operation in 1977 and 1980 respectively. In order to comply with Finnish nuclear regulation, Westinghouse and Siemens supplied equipment and engineering expertise. This unorthodox mix of US and Soviet enterprise led to the project developers being given the nickname "Eastinghouse".〔 〕〔 〕 The plant is operated by Fortum Oyj. The pressure vessel of Unit 1 was successfully heat annealed in 1996 in order to clear embrittlement caused by neutron bombardment and impurities of the welding seam between the two halves of the vessel.〔 〕 The operating licence for both units has been renewed for a 50-year lifetime, Loviisa-1 to 2027 and Loviisa-2 to 2030.〔 〕 A third reactor was proposed for the Loviisa site by Fortum Power and Heat Oy. The single reactor unit could produce up to 1000 MWt of district heating supply and from 800 - 1,600 MW of electrical generation. On 21 April 2010, the Finnish government declined the application by Fortum to build a new reactor at Loviisa.〔 〕 Spent fuel from the reactors will be stored permanently at the Onkalo spent nuclear fuel repository. In 2014 Rolls Royce took over the modernisation of safety-related systems for both units from an AREVA-Siemens consortium. The project should be completed by 2018. ==See also== *Nuclear power in Finland 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「Loviisa Nuclear Power Plant」の詳細全文を読む スポンサード リンク
