Canada's plan for the safe, long-term management of used nuclear fuel involves the containment and isolation of the waste in a deep geological repository. There cannot be any credible risk from the repository to the public or the environment, including bodies of water. No site has been selected, and many more years of discussion and study will be required before any decision can be made about a location.
The repository will be located deep underground in a suitable rock formation, which must meet site selection technical criteria for the development of a robust safety case. This approach is consistent with international best practice, and is the culmination of more than 30 years of research, development and demonstration of technologies and techniques.
The repository uses multiple barriers that include the waste form, container, sealing materials, and the host rock. The system is designed such that the failure of one component would not jeopardize the safety of the containment system as a whole.

The project will also be subject to a thorough regulatory review process, including an environmental assessment and a licensing review to ensure that it is implemented in a manner that protects people and the environment.
