Subject: Bruce A NGS, Unit 3: Release of Regulatory Hold Point for Removal of the Guaranteed Shutdown State, Major Component Replacement

Dear Mr. Burton:

The purpose of this letter is to respond to Bruce Power’s request [1] to release the second regulatory hold point (RHP-2), allowing the Guaranteed Shutdown State to be removed in Bruce A NGS Unit 3, following the Major Component Replacement outage.

Canadian Nuclear Safety Commission (CNSC) staff’s assessment [2] concluded that Bruce Power has met all of the pre-requisites established by the CNSC for RHP-2.  Therefore, as the person authorized by the Commission and pursuant to Licence Condition 15.5 of the Bruce Nuclear Generating Stations A and B Power Reactor Operating Licence 18.04/2028, I consent for RHP-2 for the guaranteed shutdown state to be removed for Bruce NGS Unit 3.

Yours sincerely,

Ramzi Jammal
Executive Vice-President and
Chief Regulatory Operations Officer
Regulatory Operations Branch
