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 proceeding with work to deploy a small modular reactor (SMR). Planning and project development are underway to deploy one ARC-100 reactor at the Point Lepreau Nuclear Generating Station site.

The project requires a provincial environmental impact assessment (EIA) to be conducted under the Government of New Brunswick’s comprehensive EIA review process, with technical support from the CNSC. The provincial EIA registration is being planned to coincide with NB’s application for the licence to prepare site.

On December 22, 2022, the Canadian 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. The proposal will undergo a comprehensive EIA by the Government of New Brunswick and an environmental protection review by the CNSC, under the Nuclear Safety and Control Act. In June 2023, NB Power applied for a licence to prepare site to construct one ARC-100 reactor at the Point Lepreau nuclear generating site.
