Canadian Nuclear Laboratories Intermediate Level Waste Storage Area

In support of ongoing operations at the Canadian Nuclear Laboratories (CNL), the construction of an Intermediate Level Waste (ILW) Storage Facility is proposed at the Atomic Energy of Canada (AECL), Chalk River Laboratories (CRL) site.  The new facility will create a centralized storage location for CNL's ILW until a final solution is developed.  The proposed site for the facility is located on approximately 2,100 m2 of previously disturbed land.  The physical activities associated with the construction of the facility will include a geotechnical and environmental characterization, upgrading road access and tie-in of existing utility services.  All physical activities will be conducted in accordance with CNL's Environmental Policy and applicable legislation.

Latest update

Notice of Determination February 16 2021. Canadian Nuclear Laboratories, on behalf of Atomic Energy of Canada (AECL) has determined that the proposed Intermediate Waste Level Storage Project at AECL’s Chalk River site is not likely to cause significant adverse environmental effects. Potential environmental effects will be managed through technically and economically feasible mitigation measures and implemented for the following: air, water, and soil. More specifically, wetlands and streams will be protected, all vegetation clearing will be conducted outside of the breeding season and turtle fences will be installed and maintained around the perimeter of the work site. Therefore, Canadian Nuclear Laboratories, on behalf of Atomic Energy of Canada may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
