Overview of Ontario Power Generation's Proposed Deep Geologic Repository for Low Intermediate Level Waste at the Bruce Site, Ontario, Canada

摘要

A Deep Geologic Repository (DGR) for the long-term management of Low and Intermediate Level Radioactive Waste is being proposed by Ontario Power Generation at the Bruce site near Kincardine, Ontario. The DGR would be located at a depth of approximately 680 m within a 200 m thick layer of low-permeability Ordovician argillaceous limestone, which is below a 200 m layer of low-permeability Ordovician shale. The repository would have the capacity for approximately 200,000 m~3 of as-disposed waste, sufficient for the current fleet of 20 OPG-owned nuclear reactors. The purpose of this paper is to provide a summary of the project.
