There’s a lot to consider when looking at nuclear power from small modular reactors (SMRs). 

Following an extensive evaluation of several potential technologies, we’ve selected the GE-Hitachi BWRX-300 as the design to advance our planning work to potentially bring nuclear power to Saskatchewan.

The BWRX-300 is a boiling water reactor that produces about 300 MW from one single unit. This innovative SMR is based on similar large scale nuclear power plants that have been in operation globally for decades.

Our selection comes from a lengthy and comprehensive evaluation that considered many factors, including:

  • safety
  • technology readiness
  • generation size
  • fuel type
  • expected costs of electricity

The following 3 technologies were considered:

We’ve been collaborating with Ontario Power Generation (OPG) since 2017, to assess suitable utility-scale SMR designs. On Dec. 2, 2021, OPG selected the GE-Hitachi design for its new small modular reactor development at the Darlington Nuclear Facility, located near Toronto.

Our technology selection allows for a pan-Canadian fleet-based approach to SMR deployment. That means the same SMR design would first be deployed in Ontario and then in Saskatchewan. This approach lowers risk for regulatory, construction and operating costs and helps maintain the project schedule.

A decision on whether to build an SMR won’t be made until 2029. The development team will continue to the next steps of the planning phase to ensure that if we choose to build, SMRs will still be an option. Our next priority is determining a suitable potential host location for a facility. Visit our Potential Facility Location webpage for more information.

This siting process will involve meaningful engagement with Indigenous Peoples, rightsholders, and the public. There are many opportunities to join the conversation around nuclear in Saskatchewan. Join the conversation on nuclear today!
