Comments invited on the summary of the Initial Project Description and funding available

January 5, 2026 – Ottawa, Ontario

The Nuclear Waste Management Organization (the NWMO) is proposing a new underground deep geological repository system designed to safely contain and isolate used nuclear fuel. As proposed, the project would provide permanent storage for approximately 5.9 million bundles of used nuclear fuel and operate for about 160 years.

This project is anticipated to be subject to an integrated assessment to meet the requirements of the Impact Assessment Act and the Nuclear Safety and Control Act. The Impact Assessment Agency of Canada (IAAC) and the Canadian Nuclear Safety Commission (CNSC) are working together on the integrated assessment to achieve the goal of "one project, one review".
