Little, R., Humphreys, Paul, King, F., Metcalfe, R., Penfold, J., Suckling, P., Towler, G., Walke, R. and Wilson, J. (2011) Postclosure Safety Assessment: System and its Evolution. Technical Report. NWMO, Ontario, Canada, Canada.

Ontario Power Generation (OPG) is proposing to build a Deep Geologic Repository (DGR) for Low and Intermediate Level Waste (L&ILW) near the existing Western Waste Management Facility at the Bruce nuclear site in the Municipality of Kincardine, Ontario. The Nuclear Waste Management Organization, on behalf of OPG, is preparing the Environmental Impact Statement (EIS) and Preliminary Safety Report (PSR) for the proposed repository.
The postclosure safety assessment evaluates the long-term safety of the proposed facility and provides supporting information for the EIS and PSR.
This report describes the DGR system and its evolution under a range of possible scenarios that might affect the system in the future. The DGR system comprises the waste and its packaging, the engineered repository, its geological setting, and the surface environment.
