See SOS Great Lakes' (also known as Save Our Saugeen Shores) analysis of 30 major ways Ontario Power Generation's proposed DGR1* has violated Canadian environmental law and regulation (the "governing documents") when it comes to "accidents, malfunctions, malevolent acts and related contingency plans."
*DGR is short for Deep Geologic Repository. DGR1 refers to OPG's plan to bury and abandon all of Ontario's (20 reactors worth!) so-called "low" and "intermediate" (some of which is considered as highly radioactive as irradiated nuclear fuel itself) radioactive waste less than a mile away from the Lake Huron shore, at its Bruce Nuclear Generating Station (BNGS) in Kincardine, Ontario, Canada.
The designation "1" is needed because of the multiple dumps targeted at various areas of Canada, especially the Great Lakes shore and basin.
DGR2 refers to the highly radioactive irradiated nuclear fuel dump-site for all of Canada (22 reactors worth) -- three municipalities near BNGS and DGR1 are still in the running for that. There is fear that DGR1 and DGR2 could simply be merged into one DGR at some point, in order to save billions, or even tens of billions, of dollars, by avoiding duplication.
DGR3 is a proposed expansion onto DGR1, for decommissioning wastes. Very late in the DGR1 licensing process, opponents pressured Canadian government regulators enough that OPG was required to admit that DGR1's proposed 200,000 cubic meter radioactive waste inventory (comprised of operational and refurbishment wastes) would someday be doubled to 400,000 cubic meters, in order to accommodate 200,000 cubic meters of decommissioning wastes.
Because of such absurdly high risks to the drinking water supply for 40 million people in two countries -- the Great Lakes -- Dave Martin of Greenpeace Canada dubbed the DGR, the DUD (short for Deep Underground Dump).
