The world’s largest source of surface fresh water is surrounded by a number of nuclear plants that have been generating power and waste for well over 30 years. Although the region has had the benefit of the power, it also has the legacy of low, medium, and high level waste that has been accumulating at these plants over the years. There is great concern over this situation because the lakes are the source of drinking water for over 30 million people.
Currently, Ontario Power Generation (OPG) has a proposal for a deep geologic repository (DGR) for low and intermediate level radioactive waste at their Bruce Nuclear facility near Kincardine, Ontario. The waste comes from the Bruce facility, as well as OPG’s Darlington and Pickering plants. It is currently stored above ground The DGR would be 680 meters below the surface of the ground and about one kilometer from the shores of Lake Huron. Kincardine offered to serve as a host community for the DGR, and no other potential sites have been considered. There has been extensive outreach in the Kincardine area over the past 10 years about the proposal, and some limited amount in Michigan. Only recently has the broader Great Lakes community become aware of the proposal and some significant concerns have been raised, primarily the proximity to Lake Huron and the lack of consideration of other sites. In addition, there is concern that this would be a precedent for more disposal sites for not only low and medium level waste, but also the high level waste from spent fuel. The proposal is under review by a Joint Review Panel formed by the Canadian Nuclear Safety Commission and the Canadian Environmental Assessment Agency.
Although OPG has done extensive engineering and geological work, the fundamental question is whether a disposal site should be located so close to one of the Great Lakes, the source of drinking water for over 30 million people. Also, should just one site be considered for something as significant as this? Some have argued that there should be no more nuclear plants on the Great Lakes until an acceptable disposal solution has been found. The reason the nuclear plants are there in the first place is the abundance of available cooling water. It seems ironic that the convenience of locating the disposal site next to the plant to limit transportation of the waste, also results in the waste staying close to Lake Huron. We should be able to do much better than this in the 21st Century.
