The evaluation of potentially suitable areas continues in greater detail in Phase 2. It is required to ensure any potential site is able to safely contain and isolate used nuclear fuel for a very long period of time. A summary of the technical and safety work done in this phase is as follows:

  • Geological field investigations provide site-specific information that is used to further assess geoscientific uncertainties identified in Phase 1: Desktop Studies and Engagement, and to provide more insight into the suitability of each study area.
  • Environment and safety evaluations focus on specific areas guided by input from the community, First Nation and Métis communities in the vicinity, and surrounding municipalities. Both field studies and discussions with local communities and First Nation and Métis communities are needed to build understanding of the environmental conditions in these smaller potential siting areas.
  • Potential transportation routes and mode(s) to each site are identified against technical and safety criteria. Transportation planning and evaluations need to be aligned with community input, which requires taking into account social values and preferences, as well as understanding and addressing social questions and concerns. This also requires understanding and addressing regulatory requirements, and inviting input from communities along potential transportation routes, as a group with a shared interest.
  • Engineering designs, safety assessments, transportation assessments, and environment assessments are further developed and refined over the course of Phase 2 to determine whether all technical and safety criteria can be met.
