After decommissioning and closure of the repository, institutional controls will be in place for an extended period of time to prevent future society from inappropriate use of the land. Institutional controls are commonly used worldwide to ensure that people and the environment are protected after decommissioning facilities associated with the use, storage or disposal of hazardous materials.
For the repository, such controls could include both active measures such as monitoring and surveillance, as well as passive measures that do not require activities on the site. Passive measures could include local land use restrictions, use of durable markers above or underground, and preservation of knowledge and memory through public records/archives.
We participate in the Nuclear Energy Agency's international collaboration on Preservation of Records, Knowledge and Memory Across Generations, which explores various topics such as markers, archives and key information files that would include information transferred across generations, transfer of responsibilities, and others.
