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 can be addressed. As we work with communities, we continue to learn and refine our activities.
- Step 1: We initiate 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 identify their interest in learning more, and we provide a detailed briefing and conduct an initial screening.
- Step 3: For interested communities that successfully complete an initial screening, we conduct a preliminary assessment of potential suitability.
- Step 4: Detailed site evaluations are completed at the site identified as having strong potential to meet project requirements in Step 3 preliminary assessments.
- Step 5: Acceptance to host the repository is confirmed.
- Step 6: Formal agreement to host the repository is ratified, subject to all regulatory requirements being met and regulatory approval received.
- Step 7: An independent, formal and public process is conducted by regulatory authorities to ensure all requirements are satisfied.
- Step 8: Construction and operation of an underground demonstration facility proceeds.
- Step 9: Construction and operation of the facility proceeds.
