Future Land Use at Whiteshell Laboratories

Restoring Whiteshell Laboratories

Canadian Nuclear Laboratories (CNL) is proposing to complete the decommissioning of the Whiteshell site and to restore the site so that it is safe for humans and the environment.

The project is being undertaken by CNL on behalf of Atomic Energy of Canada Limited (AECL). CNL is responsible for managing all the AECL sites and carrying out decommissioning and waste management work; and AECL is a Crown Corporation, and owner of all the sites, who are mandated to enable nuclear science and technology to protect the environment.

The proposed decommissioning process will minimize and safely store or dispose of all forms of waste. Then  the site will be restored so that it will serve the future needs of local communities and Indigenous nations. Extensive environmental monitoring will be put in place to ensure the area remains safe for future generations. CNL aims to completely close Whiteshell by 2027.


The Approach

The proposed approach is a technique known as in-situ disposal, where the nuclear waste remains in place, avoiding extraneous handling, shipping, and the need to build another storage facility elsewhere. In-situ disposal completes the decommissioning and contains and isolates the remaining empty reactor systems and components below grade in bedrock.

Canadian Nuclear Laboratories

CNL is Canada’s premier nuclear science and technology organization, and a world leader in developing nuclear technology for peaceful and innovative applications.
