Micro Modular Reactor Project

The Impact Assessment Act (IAA) came into force August 28, 2019. Ongoing projects with environmental assessments initiated under the Canadian Environmental Assessment Act, 2012 (CEAA 2012) and led by the CNSC, will continue under their current processes. The IAA contains provisions to enable these projects to advance in this way.

Start date: July 15, 2019
Reference number: 80182
Proponent: Global First Power
Location: Deep River, Ontario

About the project

On July 12, 2019, the Canadian Nuclear Safety Commission (CNSC) received a project description from Global First Power for the issuance of a licence to prepare the site for a Micro Modular Reactor (MMR) at the Chalk River Laboratories site, located 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.

CNSC authorization in the form of a licence issued under subsection 24(2) of the Nuclear Safety and Control Act is required in order for the project to proceed.

Before the Commission can consider an NSCA licensing decision regarding Global First Power’s proposal, an environmental assessment (EA) conducted under the Canadian Environmental Assessment Act, 2012 is required. The purpose of an EA is to identify the possible environmental effects of a proposed project, determine whether these effects can be mitigated and whether there are any remaining significant adverse environmental effects before the project is allowed to proceed.

The environmental assessment will consider all licensing phases, including site preparation, construction, operation, and decommissioning.
