Approach to decommissioning at AECL's laboratories

This series of slides presents: the Chalk River Laboratories (overview), the decommissioning organization (planning and operations), the waste management strategy (four steps: Characterization, Processing/Immobilization/Packaging, Storage, disposal), the integration of waste management and decommissioning, the free release criteria (status in Canada, AECL official criteria, AECL interim criteria, comparison to International Criteria, Release of Lands, Groundwater Monitoring, Approaches Under Consideration for Free Release, Actions) and the issues for discussion (What are the release standards? Do the same release standards apply to soil and the ground as apply to the buildings? Are release standards dose-based, or concentration based? Are there different release standards for different types of radionuclides? What are the standards for groundwater? Are surface contamination or volumetric standards used?)
