Ontario Power Generation (OPG) proposes to construct, operate, and ultimately decommission and abandon a deep geologic repository (DGR) for low- and intermediatelevel radioactive waste. The repository would accommodate waste from commercial nuclear reactors that are owned or operated by OPG, and are located at the Bruce, Pickering, and Darlington sites. This report addresses selected issues related to the DGR, in the issue category “malfunctions, accidents, and malevolent acts”, with a focus on malevolent acts. OPG has prepared an environmental impact statement (EIS) for the DGR that considers, among other issues, the potential for malevolent acts. This report shows that the EIS has not fully assessed the potential for malevolent acts associated with the DGR, and the impacts of such acts. The report offers recommendations for correcting that deficiency.
