The heat produced by the radioactive waste strikes you when you enter the storage site of Ontario Power Generation at the Bruce Nuclear Generating Station, near the shore of Lake Huron in Ontario.

Massive white containers encase spent nuclear fuel, protecting me from the deadly radiation that emanates from them. The number of containers is impressive, and my guide explained this waste is stored on an interim basis, as they wait for a more permanent solution.

I visited the site in August 2023 as part of my research into the social acceptability of nuclear waste disposal and governance. The situation in Ontario is not unique, as radioactive waste from nuclear power plants poses management problems worldwide. It’s too dangerous to dispose of spent nuclear fuel in traditional landfills, as its radioactive emissions remain lethal for thousands of years.

To get rid of this waste, organizations like the International Atomic Energy Agency believe that spent fuel could be buried in deep geological repositories. The Canadian government has plans for such a repository, and has delegated the task of building one to the Nuclear Waste Management Organization (NWMO) that’s funded by Canadian nuclear energy producers.

In 2024, NWMO selected an area in northwestern Ontario near the Township of Ignace and the Wabigoon Lake Ojibway Nation as a potential site for a deep geological repository. Now, a federal review has begun bringing the project closer to potential reality.

Such repositories raise complex ethical questions around public safety, particularly given the millennia-long timescales of nuclear waste: How to address intergenerational issues for citizens who did not produce this waste but will inherit it? How to manage the........
