Laboratory Strength Testing of Argillaceous Limestone Under Varying Saturation, Scale, Loading Rate, and Confinement Conditions
… (DGR) concept is the proposed solution for the long-term storage of nuclear waste in Canada. While site selection processes are currently underway for high-level waste storage, a low and intermediate waste storage DGR is planned for development at depth in Kincardine, Ontario. The DGR site is to …
