Ultra Safe Nuclear Corporation’s (USNC) Micro Modular Reactor (MMR) is the first and only small modular reactor to enter the formal licensing review phase with the Canadian Nuclear Safety Commission as part of the Global First Power MMR project. Global First Power – a joint venture formed by USNC-Power, a wholly owned Canadian subsidiary of Seattle-based USNC and Ontario Power Generation – will build, own and operate the proposed MMR project at the Chalk River Laboratories site.

This achievement follows more than four years of engagement by USNC with the CNSC in its vendor design review process which ensures proposed nuclear technologies achieve the necessary design and safety qualifications to be considered for full licensing. The ongoing review process encompasses not only the reactor technology but also USNC’s proprietary fully ceramic microencapsulated fuel, which was recently fabricated successfully by Canadian Nuclear Laboratories.

The MMR project at Chalk River will serve as a model for future commercial MMR installations, supporting remote off-grid customers with clean, carbon-free energy and support Canada’s climate-change goals.
