The Deep Geological Repository Project (DGR) was a proposal by Ontario Power Generation (OPG) in 2002 for the site preparation, construction, operation, decommissioning and abandonment of a deep geological radioactive waste disposal facility for low and intermediate-level radioactive waste (L&ILW). In 2005, the municipality of Kincardine, Ontario volunteered to host the facility located on the Bruce nuclear generating station adjacent to OPG's Western Waste Management Facility (WWMF). The facility would have managed L&ILW produced from the continued operation of OPG-owned nuclear generating stations at the Bruce, Pickering Nuclear Generating Station and Darlington Nuclear Generating Station in Ontario. In May 2020, after 15 years of environmental assessment, OPG withdrew its application for a construction license on Saugeen Ojibway Nation Territory. Overview Since 1974 Ontario Power Generation has stored low and intermediate-level (L&ILW) produced in its nuclear reactors at the Bruce, Pickering, and Darlington sites centrally on the Bruce nuclear site in its Western Waste Management Facility (WWMF). The proposed project was to store about 200,000 cubic meters of L&ILW from the operation of these three OPG-owned nuclear sites, about 90% of which would be low-level waste. The proposed project was divided into two phases - pre-closure and post-closure periods. The pre-closure period would have lasted about 60 years and would have included site preparation and construction, operations, and decommissioning. The post-closure period would have included a period of institutional control followed by abandonment forever. Low-level waste, which can be handled without special radiation protection, consists of materials such as mop heads, rags, paper towels, floor sweepings, and protective clothing used in nuclear stations during routine operation and maintenance. Intermediate level waste consists of non-fuel waste containing significant quantities of long-lived radionuclides. This includes materials such as used reactor core components, refurbishment wastes, ion-exchange resins and filters used to purify reactor water systems, and used reactor components such as pressure tubes. Intermediate-level waste cannot be handled without radiation protection measures. Much of the waste that would be placed in the DGR is already stored at the WWMF in engineered storage structures. The DGR would not house used nuclear fuel. History and Conceptualization Government Policies In April 2001, the Canadian federal government introduced an Act regarding the long-term management of nuclear fuel waste. Also known as the Nuclear Fuel Waste Act, this legislation came into effect on November 15, 2002. However, this legislation dealt only with the long-term management of used nuclear fuel
