Steps in the site selection process

Since 2010, we have been engaged in a multi-year, community-driven process to identify a site where Canada's used nuclear fuel can be safely stored with informed and willing hosts. The site selection process involves nine steps, with opportunities to incorporate learning along the way.


    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.
