In late 2024, Canada’s Nuclear Waste Management Organization announced the selection of a site in northwestern Ontario for its deep geological repository for the country’s used nuclear fuel.

This is a major step in a plan that was first laid out in 2010. From the beginning, the plan had been clear that any selected site must be technically safe, must be accessible for fuel transportation, and must have informed and willing host communities.

By 2020, potential sites had been narrowed from an initial set of 22 communities that had indicated interest in learning more down to two specific sites.

My primary involvement was on the technical safety side. We wanted to know that we could safely build and operate the repository at the chosen site.

While attendance at the 2025 Waste Management Conference was noticeably down this year due to the ongoing federal retrenchment, the conference, held March 9-13 in Phoenix, Ariz., still drew a healthy and diverse crowd of people working on the back end of the nuclear fuel cycle, both domestically and internationally.
