Gentilly Nuclear Generating Station (''Centrale nucléaire de Gentilly'' in French) is a formerly operational Canadian nuclear power station located on the south shore of the St. Lawrence River in Bécancour, Quebec, 100 km north east of Montreal. The Gentilly site contains the only nuclear power reactors in Quebec〔There is also a SLOWPOKE research reactor at Montreal's École Polytechnique.〕 and comprises two nuclear reactors; Gentilly-1, a 250 MW CANDU-BWR prototype, was marred by technical problems and shut down in 1977, and Gentilly-2, a 675-MW CANDU-6 reactor operated commercially by the government-owned public utility Hydro-Québec between 1983 and 2012. The Gentilly reactors were constructed in stages between 1966 and 1983 and were originally part of a plan for 30-35 nuclear reactors in Quebec. A third reactor, Gentilly-3, was scheduled to be built on the same site but was cancelled because of a drop in demand growth in the late 1970s. In October 2012, it was decided for economical reasons not to proceed with the refurbishment of Gentilly-2 and decommission the power plant instead, a process that will take approximately 50 years to complete. In December of that same year, the remaining reactor was shut down and the decommissioning process started. ==Gentilly-1== Gentilly-1 was a prototype CANDU-BWR reactor, based on the SGHWR design. It was designed for a net output of 250MW(e). The reactor had several features unique amongst CANDU reactors, including vertically oriented pressure tubes (allowing for the use of a single fuelling machine below the core), and light-water coolant. These features were intended to reduce the cost and complexity of the unit, again to make it an attractive export unit. However, the design was not successful, and over nearly 7 years recorded only 180 on-power days. Gentilly-1 is no longer in operation. 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「Gentilly Nuclear Generating Station」の詳細全文を読む スポンサード リンク
