| Title | Licensee-Identified Violation |
| Description | Hope Creek TS 3.4.2.1J Safety Relief Valves, requires that 13 of the 14 SRVs open within a lift setpoint of +/- 3 percent of-the specified code safety valve function lift setting. Contrary to this requirement, on April 18, 2009, PSEG identified that six of the 14 SRVs experienced setpoint drift outside of the TS limit. PSEG entered this issue into their CAP as notification 20411328. This finding is of very low safety significance, based on a Phase 1 SDP screening, because the SRVs would have functioned to prevent a reactor vessel over pressurization. The finding resulted in the inoperability of six SRVs, but did not result in a loss of system safety function based on engineering analyses that showed that postulated piping stresses would not exceed allowable limits. |
