Webinar: Update on OPG’s application for a licence to construct for the Darlington New Nuclear Project

Join us on July 8 for a webinar on the Darlington New Nuclear Project

Ontario Power Generation (OPG) has applied to construct a single GE Hitachi BWRX reactor of up to 300 Megawatts electric as part of its Darlington New Nuclear Project (DNNP) in the Municipality of Clarington, Ontario. CNSC staff are currently performing a licensing and technical review of OPG’s application.

The purpose of this webinar is to:

  • familiarize the public with the project and its activities
  • discuss OPG’s application for a licence to construct, for the DNNP, and give an update on the CNSC’s regulatory licensing and technical reviews, including the results of the CNSC staff’s assessment on the licence to construct
  • answer questions about the project and the next steps in the regulatory process

A 1-part public hearing was held in January 2024 to consider the applicability of the DNNP environmental assessment (EA) to the General Electric Hitachi BWRX-300 reactor, the technology selected by OPG.

On April 22, 2024, the Commission issued its record of decision determining the BWRX-300 reactor technology was not fundamentally different than the technologies considered in the EA, and that a new EA was not required. With these decisions, the CNSC continues to proceed with the OPG LTC application review.
