Canadian Regulations ØNuclear Safety & Control Act ØPassed March 1997 ØCame in to force May 2000 ØCanadian Nuclear Safety Commission ØCanada’s nuclear regulatory body ØCreated under Nuclear Safety & Control Act ØRegulatory policy P-290, Managing Radioactive Waste ØRegulatory guide G-320, Assessing the Long Term Safety of Radioactive Waste Management UNRESTRICTED / ILLIMITÉ 4

Waste Classification ØIn Canada, IAEA classification scheme has been incorporated into ØCSA standard N 292. 3 ‘Management of Low – and Intermediate Level Radioactive Waste’ ØCSA new Standard N 292. 0 ‘General principles for the management of radioactive waste’ Ø Draft out for consultation ØMost existing waste has been classified under a variety of older systems by each waste owner UNRESTRICTED / ILLIMITÉ 5

OPG DGR ØA proposed Deep Geologic Repository at the Bruce nuclear site, Ontario for OPG’s operational L&ILW ØAt 680 m depth in an argillaceous limestone formation ØCurrently in regulatory approvals process UNRESTRICTED / ILLIMITÉ 7

OPG DGR Waste Inventory Non-processible waste Compactable waste IX resin beads Incinerator ash UNRESTRICTED / ILLIMITÉ 8

OPG DGR Postclosure Safety – Relevant Features Geology ØMultiple low-permeability rock layers ØLow natural resource potential ØStable deep groundwater system, unaffected by prior glaciations ØLow permeability limits rate of resaturation into repository ØRocks are old, stable and predictable ØOrdovician rock underpressure ØSeismically quiet Waste / repository characteristics Ø 90% of wastes are low-level ØIsolated at 680 m depth ØC-14 is key nuclide at closure; ØShafts are islanded separate from waste panels ØMost long-lived radioactivity is in corrosion-resistant Zircaloy ØWaste panels are not backfilled, providing space for gases generated ØShafts will be carefully sealed, primarily with bentonite/sand UNRESTRICTED / ILLIMITÉ 9
