"High Pressure Coolant Injection [HPCI] system was declared inoperable due to failure of alarm 'HPCI Turbine Exhaust Drain Pot Hi Level' to clear. The level switch associated with the alarm is the suspected failed component. When the line is drained there is evidence of water flow but the alarm does not clear. There are no other indications of the exhaust drain line filling with water.
"As a precautionary measure, the HPCI auxiliary oil pump has been placed in pull-to-lock, which will prevent the auto initiation of HPCI. HPCI will be manually started when required and proper operations assessed to ensure the exhaust line is intact. Hourly draining of the HPCI turbine exhaust drain line has been instituted based on the previously established frequency of the alarm.
"HPCI is considered available.
"All remaining ECCS systems are operable.
"The NRC Senior Resident Inspector has been notified of this event." |

| Unit | SCRAM Code | RX CRIT | Initial PWR | Initial RX Mode | Current PWR | Current RX Mode | | 1 | N | Y | 19 | Power Operation | 9 | Power Operation | Event Text PLANT SHUTDOWN WAS INITIATED TO COMPLY WITH TECH SPEC. 3.6.1.1. PRIMARY CONTAINMENT INTEGRITY.
"At 1230 hours the service water isolation valve to the Turbine Building Area (1SW26) was declared inoperable due to the inability to close the valve. This condition was identified while investigating a low service water pressure in the turbine building during start up activities from the Salem 1 sixteenth refueling outage.
"With 1SW26 inoperable, Technical Specification 3.6.1.1 requires that the inoperable valve be restored to operable within one hour or be in hot standby within the next 6 hours and in cold shutdown in the next 30 hours. Since the valve cannot be restored to operable within the one hour action statement time, PSEG commenced a unit shutdown at 1330 hours.
"It is expected that repairs can be performed while in hot standby conditions.
"This report complies with the reporting requirements of 10 CFR 50.72 (b)(2)(i)."
The NRC Resident Inspector was notified of this event by the licensee. | |
