Peer review

One way we ensure our work is based on the best science is by working with leading scientists and experts from universities, in the industry or as part of international research groups.

Site Selection Review Group

The Site Selection Review Group was comprised of two internationally respected members from different professional backgrounds. These review group members had knowledge and experience in nuclear waste-related siting processes and international best practices.

The group provided independent advice and guidance on the NWMO’s final site selection approach for a deep geological repository for used nuclear fuel. Its purpose was to ensure the decision-making process was reasonable, comprehensive, credible and rigorous. Its mandate was completed in 2024.

The members of the Site Selection Review Group were:

Tom Isaacs, chair of the Site Selection Review Group, lead advisor on the Blue Ribbon Commission on America’s Nuclear Future and senior advisor to the Nuclear Threat Initiative.
Claes Thegerström, former president of the Swedish Nuclear Fuel and Waste Management Company.

Each of the members was independent of the NWMO, the site selection process and the municipal and Indigenous communities involved in the process.

Environmental Review Group

The Environmental Review Group advises the NWMO on developing an effective impact assessment process, including engagement and the interweaving of Indigenous Knowledge and western science, as well as international best practices.

The GRG is made up of five internationally recognized experts from Canada, Sweden, Switzerland, and Australia. They possess extensive multidisciplinary experience relevant to the siting of a deep geological repository.

Geoscientific Review Group

The NWMO established the Geoscientific Review Group to ensure site evaluations are conducted in a consistent and traceable manner using international best practices.

Scientific journal reviews

The NWMO regularly undergoes independent peer reviews when publishing technical research results in scientific journals and at conferences. On specific topics, we seek out peer reviews or request that state-of-science reviews be prepared by leading experts.
