Micro Modular Reactor Project

Global First Power is proposing the site preparation, construction, operation, and decommissioning of a Micro Modular Reactor nuclear plant at the Chalk River Laboratories site, in Renfrew County, Ontario, approximately 200 km northwest of Ottawa. The project would provide process heat to an adjacent plant via molten salt, and produce approximately 15 Megawatt (thermal) of process heat to generate electrical power and/or heat, over an operating life-span of 20 years.

The project requires an environmental assessment under the Canadian Environmental Assessment Act, 2012, and approval by the Canadian Nuclear Safety Commission for a licence under the Nuclear Safety and Control Act in order for the proposed project to proceed. However, before the Canadian Nuclear Safety Commission can consider making a decision on issuing a licence, an environmental assessment decision affirming that the proposed activities will not cause significant adverse environmental effects is required.

Latest update

December 15, 2021 - Global First Power is expected to submit a Draft Environmental Impact Statement (EIS) for the project in late 2022, in order to meet information requirements outlined for the scope of the review in the March 23, 2021 letter to Global First Power and Guidelines for the Preparation of an Environmental Impact Statement revised in March 2021.
