based on operating experience, equipment reliability, and plant risk and is controlled under the Surveillance Frequency Control Program. Testing slave relay K750 at power would result in opening the PORVs and depressurizing the RCS. If the PORV block valves are closed, there is not enough pressure to open the PORVs.
