Bruce Nuclear Generating Station is a Canadian nuclear power station located on the eastern shore of Lake Huron, in the communities of Inverhuron and Tiverton, Ontario. It occupies 932 ha (2300 acres) of land.〔(【引用サイトリンク】 title=Global Security Article )〕 The facility derives its name from Bruce County in which it is located, in the former Bruce Township. It is the largest nuclear generating station in the world by total reactor count, and number of operational reactors. Formerly known as the Bruce Nuclear Power Development (BNPD),〔 the facility was constructed in stages between 1970 and 1987 by the provincial Crown corporation, Ontario Hydro. In April 1999 Ontario Hydro was split into 5 component Crown corporations with Ontario Power Generation (OPG) taking over all electrical generating stations. In June 2000, OPG entered into a long term lease agreement with private sector consortium Bruce Power to take over operation of the Bruce station. In May 2001, Bruce Power began operations. The lease is for 18 years (until 2019) with an option to extend a further 25 years (to 2044). The Bruce station is the largest nuclear facility in the world (the Kashiwazaki-Kariwa in Japan is larger but not currently operating),〔(【引用サイトリンク】url=http://www.industcards.com/top-100-pt-1.htm )〕〔(Japan Times: TEPCO may ask U.S. utility to inspect Kashiwazaki-Kariwa nuclear plant )〕 comprising 8 CANDU nuclear reactors having a total output of 6,272 MW and 7,276 MW (net) when all units are online. The Bruce station has three double-circuit 500 kV transmission lines going out of it to feed the major load centres in southern Ontario, in addition to three double-circuit 230 kV lines serving the local area.〔(【引用サイトリンク】title=The Need for More Transmission in Bruce Region )〕 The station is the largest employer in Bruce County, with 3800 workers. In November 2009, the Canadian Nuclear Safety Commission renewed Bruce Power’s operating licences for 5 years (until 2014), as well as giving permission to refuel units 1 and 2. In May 2014, the CNSC extended the license to May 2015. Public hearings are tentatively schedule for early 2015 in Ottawa and Kincardine.〔(【引用サイトリンク】 title=CNSC Extends Bruce Power's Operating Licence Until May 2015 )〕 A new operating license has been granted for June 1, 2015 to May 31, 2020. 〔(【引用サイトリンク】 title=Canadian Nuclear Safety Commission renews Bruce Power's power reactor operating licences )〕 ==Description== The eight reactors are arranged into two plants (A and B) of four reactors. Each reactor is within a reinforced concrete containment, with eight steam generators. The steam generators are 12 m tall, and weigh 100 tonnes each. Reactors share fuelling machines which travel in a duct traversing the entire plant. The duct is cut through solid rock beneath the reactors, and doubles as part of the pressure relief system, connected to the vacuum building.〔(【引用サイトリンク】title=Nuclear Engineering and Design - Pressure relief structures of multi-unit candu nuclear power plants )〕 Each reactor has its own turbine generator set, with one high pressure turbine and three low pressure turbines driving one generator.〔〔()〕 The turbine hall (about 400 m long) at each plant houses the four turbine generator sets. Cooling water is taken from Lake Huron.〔 There is (originally) one control room per 4 reactors. 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「Bruce Nuclear Generating Station」の詳細全文を読む スポンサード リンク
