In-situ Decommissioning

Proven technology – In-situ decommissioning has been in use for over six decades in the United States. A well-understood decommissioning solution, in-situ technology and expertise has been developed and grown over this period.  Several sites in the United States have used this approach:

Environmentally sound – CNL will ensure that In-situ decommissioning is safe for the environment. The WR-1 reactor project is subject to an environmental assessment.  The Environmental Assessment process is a robust process led by the Canadian Nuclear Safety Commission and conducted under the Canadian Environmental Assessment Act, 2012.  The Environmental Assessment will evaluate project activities and the mitigation strategy for any possible environmental effects throughout the life of the project.

The Environmental Assessment process will determine CNL’s actions during the implementation of this project, leading to continued responsible environmental stewardship. 

CNL has a solid record of accomplishment on environmental protection. CNL’s environmental policy, and Environmental Management System monitor and inform reporting on CNL’s environmental performance.

Safe – The proposed strategy of in-situ decommissioning provides the best decommissioning option for workers, the public and the environment. The chosen decommissioning technique minimizes safety risks; for example it will reduce the chance of dose to workers, and also limits worker exposure to the risk of industrial accident. It reduces materials handling, packaging, temporary storage and unnecessary movement of materials; all factors which help minimize the risk to the environment.

The decommissioning of the WR-1 reactor will be conducted in accordance with all applicable codes and best practices.
