Gentilly Nuclear Generating Station (Centrale nucléaire de Gentilly in French) is a former nuclear power station located on the south shore of the St. Lawrence River in Bécancour, Quebec, 100 km north east of Montreal. The site contained 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. These were the only power generating nuclear reactors in Quebec.[note 1]
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.[1][2] 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.[3]
In October 2012, it was decided for economic reasons not to proceed with the refurbishment of Gentilly-2, and to decommission the power plant instead. The process will take approximately 50 years to complete.[4] In December of that same year, the remaining reactor was shut down and the decommissioning process started.[5]
In August 2023, Hydro-Québec reported it was assessing the state of the plant to determine whether or not the Gentilly-2 CANDU reactor could be recommissioned. This came as the province of Quebec looked towards options to increase its production of clean electricity.[6] It was decided to not proceed with recommissioning Gentilly-2 due to social acceptability issues.[7]
