Canada’s own deep geological repository would be built more than 500 metres underground, surrounded by a natural barrier of solid rock that has been disconnected from the water table for millions of years. To visualize that depth, imagine an excavation more than five times as deep as the House of Commons Peace Tower is tall. The NWMO has been working to identify a site for the deep geological repository since 2010. Twenty-two municipalities and Indigenous communities expressed interest in exploring their potential to host it.
Borehole drilling completed in two potential locations
The Nuclear Waste Management Organization (NWMO) announced the completion of their deep borehole drilling projects in both Teeswater and Ignace. A press release on April 7 said, “The completion of the last borehole at the potential site in the SON-South Bruce area follows on work in the Wabigoon-Ignace area, which wrapped up in November 2021 after five years of intensive field study that started in 2017.” “We need to be sure that used nuclear fuel can be safely contained in the rock to ensure water, people and the environment are safe,” said Sarah Hirschorn, director of geoscience at the NWMO.
