Gentilly-2 nuclear facilities
Source: Hydro-Québec
Current status: Decommissioned nuclear facility
The Gentilly-2 Facilities are on the south shore of the St. Lawrence River in Bécancour, Quebec, around 15 km east of the city of Trois-Rivières. The facilities are owned and operated by Hydro-Québec.
The Gentilly-2 CANDU reactor was permanently shut down on December 28, 2012, and was completely defuelled by September 3, 2013. The reactor was transferred to a safe storage state in December 2014. This means that its fuel was stored in used fuel pools (wet storage) or in CANSTOR modules (dry storage).
The transfer of all irradiated fuel to dry storage CANSTOR modules was completed in December 2020.
