> 410 psia and UV-651 and UV-653 OR UV-652 and UV-654 NOT FULLYCLOSED A~A None Monitor the following on Panel B02 to verify pressure and the validity of the alarm.
~ PRESSURIZER PRESSURE, RCA-PI-103
~ PRESSURIZER PRESSURE, RCB-PI-104
~ PRESSURIZER PRESSURE, RCC-PI-105
~ PRESSURIZER PRESSURE, RCD-PI-106
- 2. Determine the cause of the overpressure condition.
Ifthe Low Temperature Overpressure Relief Valves are in service, correct the causes of the pressure transient.
- 2. Warn personnel in Containment of the possible radiological hazard.
- 3. Ifthe LTOP Relief Valves were originally isolated, close/check closed the following valves on Panel B02:
~ RC LOOP 1 S/D CLG-LPSI PUMP A SUCT VLV, SIA-UV-651
~ RC LOOP 1 S/D CLG-LPSI PUMP A SUCT VLV, SIC-UV-653 RC LOOP 2 S/D CLG-LPSI PUMP B SUCT VLV, SIB-UV-652
~ RC LOOP 2 S/D CLG-LPSI PUMP B SUCT VLV, SID-UV-654
- 4. Perform independent verification on all applicable valves, breakers and components that were operated by this alarm response per 02AC-OZZ01, Independent Verification of Valves, Breakers and Components.
