The Canadian Nuclear Safety Commission (CNSC) has officially granted Hydro-Québec the authorization to proceed with the decommissioning of the Gentilly-2 nuclear power station. This regulatory approval marks a significant step in the long-term project to dismantle the facility, which ceased electricity production in December 2012. According to the Canadian Nuclear Safety Commission, the decision follows a comprehensive public hearing process and rigorous technical reviews to ensure the safety of workers, the public, and the surrounding environment.
Located in Bécancour, Quebec, the Gentilly-2 reactor was the province’s only nuclear power plant. The decommissioning project is expected to unfold over several decades, transitioning the site into a state of “safe storage” before final dismantling. The CNSC confirmed that the issued license, which came into effect on June 1, 2024, permits Hydro-Québec to carry out all necessary activities to safely manage the radioactive materials and infrastructure remaining at the site, as documented in the official project outline provided by Hydro-Québec.
Regulatory Oversight and Safety Mandates
The decommissioning process is subject to stringent federal oversight. The CNSC mandates that Hydro-Québec adhere to strict environmental protection protocols throughout the dismantling phases. These protocols involve the continuous monitoring of radiation levels and the secure management of spent nuclear fuel, which is currently housed in dry storage containers on-site. The CNSC’s regulatory framework ensures that the utility operator maintains financial and technical responsibility for the site until it meets the criteria for release from regulatory control.
Hydro-Québec has stated that the primary objective of this phase is to reduce the footprint of the facility and prepare the site for long-term monitoring. This involves the decontamination of structures and the eventual demolition of buildings that are no longer required for the safe storage of radioactive waste. The utility must report periodically to the commission to demonstrate compliance with the conditions set out in the new decommissioning license.
What Happens Next for the Gentilly-2 Site
With the license now in effect, the focus shifts to the practical implementation of the decommissioning plan. The project is divided into distinct stages, prioritizing the stabilization of the reactor building and the management of radioactive components. Local stakeholders and residents in the Bécancour region are encouraged to monitor ongoing developments through official channels, as the site will remain under active management for the foreseeable future.
Further information regarding the schedule of site activities and safety reports can be accessed through the Hydro-Québec project portal. The utility is required to maintain a public information program to keep the community informed about milestones and any potential environmental impacts associated with the decommissioning work. As the project progresses, the CNSC will continue to conduct inspections to verify that all activities align with the approved safety case.
