Proposed nuclear facility – NB Power's ARC-100 Project at the Point Lepreau Nuclear Generating Station site

New Brunswick Power (NB Power), in partnership with ARC Clean Technology Canada, is proposing to deploy one ARC-100 small modular reactor (SMR) at the Point Lepreau Nuclear Generating Station site in New Brunswick. In June 2023, CNSC staff received an application for a licence to prepare site for the proposed SMR, and the application is currently undergoing regulatory review under the Nuclear Safety and Control Act, which will include an environmental protection review.

The proposed project is also undergoing a comprehensive environmental impact assessment (EIA) by the Government of New Brunswick. CNSC staff are providing technical support throughout the provincial EIA process as members of the Technical Review Committee.

In December 2022, the federal Minister of Environment and Climate Change responded to a designation request for the project and concluded that the project did not warrant designation pursuant to subsection 9(1) of the Impact Assessment Act.
