The Safety Assessment Review Group was established in 2023. It is made up of a group of four internationally recognized experts in safety case and safety assessments from Sweden, Switzerland and the United Kingdom.

The group provides expert advice and guidance to ensure that safety assessments are conducted in a manner consistent with best international practices. The group reviews and provides recommendations on the development of the safety case, as well as the approach, methods and results of the pre-closure and post-closure safety assessment studies and reports produced to support the regulatory decision-making process for the used nuclear fuel repository.

The NWMO established the Community-Based Transportation Working Group to seek feedback from a broad range of individuals across Ontario, Québec and New Brunswick about how to implement the organization’s transportation planning framework, including collaborative transportation planning and engagement and dialogue for the transportation program. The members of the working group are individuals acting as independent advisors.

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.

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.
