The Olkiluoto Nuclear Power Plant ((フィンランド語:Olkiluodon ydinvoimalaitos)) is on Olkiluoto Island, which is on the shore of the Gulf of Bothnia in the municipality of Eurajoki in western Finland. It is one of Finland's two nuclear power plants, the other being the two-unit VVER Loviisa Nuclear Power Plant. The plant is owned and operated by Teollisuuden Voima (TVO), a subsidiary of Pohjolan Voima. The Olkiluoto plant consists of two Boiling Water Reactors (BWRs) with 860 MWe each. Unit 3, an EPR reactor, is still under construction, but various problems with workmanship and supervision have created costly delays which have been the subject of an inquiry by the Finnish nuclear regulator Säteilyturvakeskus (STUK).〔 〕 In December 2012, Areva estimated that the full cost of building the reactor will be about €8.5 billion, or almost three times the delivery price of €3 billion.〔〔 A license for a fourth reactor to be built at the site was granted by the Finnish parliament in July 2010,〔 〕〔 〕〔 〕 but discontinued by the government in September 2014. TVO has the option to reapply for the license in the future.〔 According to Financial Times in December 2014 construction of unit 3 has descended into farce as it is currently expected to open nine years late and several billions of euros over budget.〔(Finland and Russia deepen energy ties ) Financial Times December 2, 2014〕 == Units 1 and 2 == Units 1 and 2 consists of two BWRs with 880 MW each.〔 〕 The main contractor was ASEA-Atom, now a part of Westinghouse Electric Sweden AB. Turbine generators were supplied by Stal-Laval. The units' architecture was designed by ASEA-Atom. The reactor pressure vessels were constructed by Uddcomb Sweden AB, and reactor internal parts, mechanical components by Finnatom. The electrical equipment was supplied by Strömberg.〔 〕 Unit 1 was constructed by Atomirakennus and unit 2 by Jukola and Työyhtymä.〔 (【引用サイトリンク】 publisher = International Nuclear Safety Center )〕〔 (【引用サイトリンク】 publisher = International Nuclear Safety Center )〕 Unit 1 achieved its initial criticality in July 1978 and it started commercial operations in October 1979.〔 Unit 2 achieved its initial criticality in October 1979 and it started commercial operations in July 1982.〔 Major upgrades were carried out to the units in 2010 and 2011, including replacement of turbines and generators, isolation valves, electrical switchgear and seawater pumps. The upgrades increased the net electrical output by 20 MW to 880 MW each.〔 〕 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「Olkiluoto Nuclear Power Plant」の詳細全文を読む スポンサード リンク
