GE Vernova Hitachi Nuclear Energy (GVH) has received approval to begin construction of Canada’s first BWRX-300 small modular reactor (SMR). The Province of Ontario and Ontario Power Generation (OPG) cleared the project to move forward at the Darlington site.

Construction of the first unit will begin soon. Completion is expected by the end of the decade. The Darlington site will eventually host four BWRX-300 reactors.

The BWRX-300 is a 300 MW, next-generation reactor. It is the 10th evolution of boiling water reactor design, built on decades of operating experience. GVH is using a standard design and a proven delivery model, along with experience in regulatory collaboration between countries.

GE Vernova has been active in Canada for over 130 years. Its nuclear history in the country dates back to the 1950s, when it helped build the Nuclear Power Demonstration (NPD) reactor—the foundation of the CANDU reactor fleet.

This project marks a major milestone in Canada’s push for clean, reliable nuclear energy.

“In deploying the first BWRX-300 small modular reactor, Ontario is leading the way globally in the deployment of SMRs,” said Maví Zingoni, CEO, Power, GE Vernova. “Our work with OPG and project partners will serve as a benchmark for the global nuclear industry.”

“As the world looks to adopt SMR technology, we are proud to be embarking on construction of the first BWRX-300 with OPG, AtkinsRéalis and Aecon” said Lisa McBride, Canada Country Leader, GVH. “Ontario’s supply chain is expected to contribute significantly to this project bringing substantial economic benefits to the province including the creation of thousands of jobs during manufacturing, construction and operation.”
