The decommissioning of Whiteshell Laboratories began in 2003, after the Canadian Nuclear Safety Commission approved an overall decommissioning framework and then issued a site decommissioning licence. Since that time, redundant buildings have been demolished, and new enabling facilities for waste handling have been constructed.
The next major step in the plan is the decommissioning of the WR-1 Research Reactor itself, one of the largest and most complex facilities on the site. The proposal for that project has been sent to the Canadian Nuclear Safety Commission for approval.
CNL plans to complete the decommissioning of the Whiteshell site by 2027.
CNL monitors environmental performance at the Whiteshell site and the results confirm continued responsible stewardship of the site.
