| Title | Licensee-Identified Violation |
| Description | Hope Creek Technical Specification surveillance requirement 4.7.1.1.b. requires, in part, that the SACS subsystems shall be demonstrated to be operable at least once per 18 months by verifying that each automatic valve servicing safety-related equipment actuates to its correct position on the appropriate test signal(s). Contrary to this requirement, PSEG did not perform adequate testing to demonstrate operability of the SACS HX bypass valves by verifying automatic closure on high temperature based on an appropriate test signal. Specifically, on June 8, 2010, PSEG determined that the SACS HX bypass valves (EG-HV-2457 AlB) were not adequately tested prior to June 8, 2010. As an immediate corrective action, PSEG closed the bypass valves and declared them inoperable. Additionally, PSEG placed this issue in the CAP as notification 20470714 and initiated actions to adequately test the valves. This licensee-identified NCV is of very low safety significance based on a Phase 1 SDP screening, because plant historical data from 2007 to 2010 indicated the HX bypass valves closed multiple times in response to increasing SACS temperatures. Thus, there is reasonable assurance the bypass valves would have closed when required, and the safety function of SACS would be maintained. |
