Confidence in safety: Revell Site

The Nuclear Waste Management Organization (NWMO) is presently in a multi-year process of identifying a safe site for a deep geological repository for Canada's used nuclear fuel in an area with informed and willing hosts. The fundamental safety objective of the project is to protect humans and the environment, including water, from the effects of radioactive or hazardous substances present in the used fuel. The used fuel radioactivity naturally decreases with time. The deep geological repository, including engineered and natural barriers, provides long-term containment and isolation; in particular while this natural radioactivity decay occurs. Previous discussions and studies have identified the Revell Site in northwestern Ontario and the South Bruce Site in southern Ontario as candidate repository sites. This report focuses on the Revell Site. It summarizes the results as of early 2022 indicating that this site would be suitable from a technical perspective for hosting a repository. It is intended to support public discussion around site selection. (author)
