In 1997, Atomic Energy of Canada Limited (AECL) decided to discontinue research programs and operations at the Whiteshell Laboratories near Pinawa, Manitoba. AECL is currently seeking a licence from the Canadian Nuclear Safety Commission (CNSC) to decommission the facility. CNSC determined that an environmental assessment is required before a CNSC licence application can proceed.
In November 1999, CNSC issued a scope of project and assessment document on the environmental assessment for comment. The final version of this document, published on December 22, 1999, was used to direct the environmental assessment studies. The environmental assessment was submitted to the Minister of the Environment and the Canadian Environmental Assessment Agency in December 2001 for public review and decision under the Canadian Environmental Assessment Act.
On April 2, 2002, the Minister of the Environment referred the project back to the responsible authorities, including CNSC. The Minister recommended that CNSC, jointly with Fisheries and Oceans Canada, ensure that all mitigation measures and recommendations described in the environmental assessment are implemented. CNSC will ensure this occurs, should regulatory approval be given for the decommissioning of the facility.
With this decision, CNSC will continue its licensing assessment related to the AECL proposal. A formal licence application from AECL is anticipated shortly. When this occurs, CNSC would undertake a detailed review of the application and submit recommendations to the Commission on the licensing of this decommissioning project.
The Whiteshell Laboratories continue to be maintained by AECL under an existing CNSC operating licence.
CNSC maintains a public registry of documents related to its Environmental Assessments. Lists and copies of documents may be obtained upon request. For questions or information related to the environmental assessment of this project, please contact:
