About the Proposal

Global First Power is proposing the site preparation, construction, operation, and decommissioning of a single small modular reactor, using Micro Modular Reactor (MMR) technology. The proposed project is located at the Chalk River Laboratories site, in Renfrew County, Ontario, approximately 200 km northwest of Ottawa. The proposed project includes a nuclear plant, which would contain a MMR High Temperature Gas-cooled Reactor that would provide process heat to an adjacent plant, via molten salt. The MMR would produce approximately 15 Megawatt (thermal) of process heat to generate electrical power and/or heat, over an operating life-span of 20 years.

Under the Nuclear Safety and Control Act, Global First Power's proposal requires approval and licensing by the Canadian Nuclear Safety Commission (CNSC). An environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required, and an EA decision affirming that the proposed activities will not cause significant adverse environmental effects, before the CNSC can make a licensing decision on this proposal.
