SUBJECT: Darlington NGS - Unit 2 Return to Service: Request for CNSC Consent to Remove the Regulatory Hold Point Prior to Fuel Load

Dear Mr. Reiner:

The purpose of this letter is to respond to Ontario Power Generation’s (OPG) request [1] to remove Regulatory Hold Point (RHP-1), allowing fuel to be loaded in the refurbished Darlington Unit 2 reactor core.

Canadian Nuclear Safety Commission (CNSC) staff’s assessment [2, 3] concluded that OPG has met all the pre-requisites established by the Commission to remove RHP-1. Therefore, as the person authorized by the Commission and pursuant to Licence Condition 15.4 of the Darlington Nuclear Generating Station (DNGS) Power Reactor Operating Licence 13.01/2025, consent to remove RHP-1 is hereby granted and fuel may now be loaded into the Unit 2 core.

Yours sincerely,

Ramzi Jammal
Executive Vice-President and
Chief Regulatory Operations Officer
