ottawacitizen - The poster child for nuclear waste disposal in Canada is a proposed man-made rock cavern near the eastern shore of Lake Huron.
Unlike a planned national deep geological repository for intensely radioactive spent reactor fuel, the "deep rock vault" at the Bruce Nuclear Generation Station in Tiverton, Ont. will handle only low and medium radioactive waste. Highlevel nuclear waste is forbidden.
Ontario Power Generation (OPG), the public utility that owns the reactors, is seeking federal permission to construct a "vault" 680-metres below the Bruce complex.
About 200,000 cubic metres of radwaste - about a century's worth - from the Darlington, Pickering and Bruce nuclear operations is to go into in a vault carved in tectonically stable shale and limestone, a kilometre from the lake.
OPG says the 450 million-year-old rock formations will remain stable for at least the next few million years and, "limit the movement of radioactivity to very slow rates.
