Decommissioning of the Whiteshell Laboratories has been underway for more than a decade, following approval of an overall decommissioning framework for the site, the conducting of an environmental assessment and the subsequent issuing of a site decommissioning licence by the Canadian Nuclear Safety Commission (CNSC). During that time, redundant buildings have been demolished, and new enabling facilities for waste handling have been planned and constructed.
Throughout all of this, environmental performance has continuously been monitored. A renewed strategic plan has recently been developed. The new plan will see decommissioning of the main laboratory campus largely complete by 2028. Planning documents to begin decommissioning of the WR-1 Research Reactor, by far the largest and most complicated facility on the site, were recently submitted to the CNSC.
