Siting process: Used fuel repository
In 2010, we launched a multi-year, community-driven process to identify a site where Canada’s used nuclear fuel will be safely stored in a deep geological repository. In 2024, we selected a site in northwestern Ontario to take into the regulatory decision-making process. The process involves nine steps, with opportunities for learning along the way.
Steps in the process
The steps were designed to ensure the pace and manner of moving through them could be flexible and adaptive, while also ensuring the needs of communities engaged in the process could be addressed. As we work with communities, we continue to learn and refine our activities.
- Step 1: We initiated the siting process with a broad program to provide information, answer questions and build awareness among Canadians about the project and siting process.
- Step 2: Communities identified their interest in learning more, and we provided detailed briefings and conducted initial screenings.
- Step 3: For interested communities that successfully completed an initial screening, we conducted a preliminary assessment of potential suitability.
- Step 4: Detailed site evaluations were initiated at the site identified as having strong potential to meet project requirements in Step 3 preliminary assessments.
- Step 5: Acceptance to host the repository was confirmed.
- Step 6: Formal agreements to host the repository were ratified, subject to all regulatory requirements being met and regulatory approval received.
- Step 7: An independent, formal and public process is being conducted by regulatory authorities to ensure all requirements are satisfied.
- Step 8: Construction and operation of an underground demonstration facility will proceed.
- Step 9: Construction and operation of the facility will proceed.
