Proposed nuclear facility – Global First Power Micro Modular Reactor Project

Global First Power (GFP) is seeking CNSC approval for a licence to prepare site (LTPS) for a micro modular reactor (MMR) at the Chalk River Laboratories (CRL) site in Renfrew County, Ontario, approximately 200 kilometres northwest of Ottawa.

The proposed project includes a nuclear plant that contains a high-temperature gas-cooled reactor providing up to (approximately) 45 megawatts (thermal) of process heat to an adjacent plant via molten salt, which will generate electrical power and/or heat over an operating lifespan of 40 years.

A CNSC licence is required under subsection 24(2) of the Nuclear Safety and Control Act (NSCA) in order for the project to proceed. However, an environmental assessment (EA) is required under the Canadian Environmental Assessment Act, 2012 (CEAA 2012) before the Commission can make an NSCA licensing decision.

Licensee: Global First Power
Reactor type: High-temperature gas-cooled reactor
Owner: Global First Power
Number of units: Up to 1 reactor
Installed capacity: Up to 45 MWth
Status: Application under review
Licensing documentation: Request a copy of GFP’s licence application by emailing, or visit GFP’s website.
Facility website: Global First Power
