How do we inspire the next generation of innovators?

This summer, our employees connected with nearly 600 students across six university campuses, exploring how STEM, innovation and sustainability can help address complex challenges and shape Canada's nuclear future. The sessions encouraged curiosity and new ways of thinking, inspiring students to see how their ideas can make a real-world impact.

We are pleased to partner with Shad Canada to help inspire informed .

Safety is at the core of our work.

To help uphold this commitment, the independent Safety Assessment Review Group reviews the approach, methods, data and results behind our safety assessments.

Their global expertise helps ensure our work aligns with international best practices and supports strong, science-based decisions for the safe long-term management of used nuclear fuel in a deep geological repository.

Have your say about the proposed site selection process for our second repository.

We’re planning a second deep geological repository to safely manage Canada’s intermediate-level and non-fuel high-level radioactive waste, as well as potentially store used nuclear fuel from future nuclear projects as Canada’s nuclear energy capacity grows.

Feedback from Indigenous Peoples and Canadians will help us confirm and refine the site selection process for the second repository, which is expected to launch in 2028. To provide input, answer a few questions about our proposed approach, or request a presentation, please visit our second repository engagement portal: https://nwmo.co/4gESoAo

It's been a pleasure connecting with municipal leaders and partners at the Association of Municipalities of Ontario - AMO 2026 Conference this week.

Our staff engaged with conference attendees at the NWMO’s booth and shared information on our mandate for the safe, long-term management of Canada's intermediate- and high-level radioactive waste.

We also hosted a successful workshop focused on our plans for the safe, long-term management of intermediate- and high-level radioactive waste and the development of a second deep geological repository.

We appreciate everyone who connected with us and provided valuable feedback.

In Canada used nuclear fuel is a stable solid ceramic material, that is sealed in specially designed corrosion-resistant tubes that are formed into a bundle.

When removed from a nuclear reactor, the bundle looks the same as when it went in, but it is highly radioactive and will remain that way for a long time. That’s why Canada’s plan involves containing and isolating used nuclear fuel in a deep geological repository. It will protect people and the environment for generations to come.

Water protection is at the core of what we do. A deep geological repository is designed to protect drinking water, lakes, and rivers by safely isolating used nuclear fuel deep underground. Supported by years of research, it is the best way to protect people and the environment.
