PHAI Licence Renewal

Canadian Nuclear Laboratories (CNL) has submitted an application to the Canadian Nuclear Safety Commission (CNSC) for the renewal of the Port Hope Project Waste Nuclear Substance Licence for a term of 10 years.

The current licence expires on December 31, 2022.

As part of the application, CNL is requesting a consolidation of the Port Hope licence and the Port Granby Project Waste Nuclear Substance Licence into a single, ten-year Port Hope Area Initiative (PHAI) licence allowing CNL to:

Continue the cleanup
of historic low-level radioactive waste from various sites in Port Hope for safe, long-term containment and monitoring

Continue maintenance and monitoring
of the capped and closed Port Granby Long-Term Waste Management Facility

Reduce the administrative burden
of holding two separate licences for similar projects under the PHAI portfolio

Canada’s nuclear regulator is evaluating the project at a hearing:
