Regulatory hold points for new reactor facilities

Licensees are required to adhere to regulatory hold points (RHPs) established during the licensing process for new reactor facilities.

RHPs for new reactor facilities primarily focus on the analysis and design of structures, systems and components that are important to safety.

Mandatory checkpoints

RHPs are established by the Commission during a licensing proceeding and may vary depending on the type of facility and the licensing phase of the project.

Darlington New Nuclear Project

The Commission established 3 RHPs in the decision to authorize Ontario Power Generation Inc. to construct 1 BWRX-300 reactor at the Darlington New Nuclear Project site:

1. Installation of the reactor building foundation
2. Installation of the reactor pressure vessel
3. Fuel-out commissioning
