Nuclear Facility – Gentilly-2

The Gentilly-2 Facilities are located on the south shore of the St. Lawrence River in Bécancour, Quebec, around 15 km east of the city of Trois-Rivières, and 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. In December 2014, the reactor completed the transition to a safe storage state, meaning that its fuel was stored in used fuel pools (wet storage) or in CANSTOR modules (dry storage). In December 2020, the transfer of all irradiated fuel to dry storage CANSTOR modules was completed.
