BO IEL N/A Y

On November 30, 2022, Hope Creek Generating Station (HCGS) discovered an electrical jumper that was installed on October 5, 2022 and should have been removed on October 10, 2022. The cause is human performance error. The jumper bypassed isolation actuation instrumentation associated with residual heat removal (RHR) system shutdown cooling (SDC) mode isolation. Specifically, it rendered one channel of a two-channel interlock that protects the RHR system from over-pressurization inoperable. The interlock prevents opening SDC valves when reactor pressure is above 82.0 psig. HCGS did not take required action required by technical specifications (TS) for this condition before entering applicable operational conditions on October 28, 2022. Consequently, HCGS was in a condition prohibited by TS from October 28 to November 30, 2022. HCGS removed the jumper to restore operability of the interlock shortly after discovery and completed individual performance management.

SAFETY CONSEQUENCES AND IMPLICATIONS

There was no safety consequence or implication because the redundant isolation actuation instrumentation channel was operable throughout this event to provide over pressure protection for the RHR SDC piping, and the affected valves remained closed for the entirety of the event.

PREVIOUS EVENTS No similar licensee event report (LER) or corrective action occurrences were found following a review of station LERs and the corrective action program for the past three years.

CORRECTIVE ACTIONS

1. The jumper was removed;
2. Performance management for the individual(s) involved was completed.

COMMITMENTS

There are no regulatory commitments in this LER.
