| Title | Licensee-Identified Violation |
| Description | In Modes 1, 2, and 3, Hope Creek TS 3.4.2.1, Safety Relief Valves, requires that 13 of the 14 SRVs open within of +/- 3 percent of the specified code safety valve function lift settings or else be in Mode 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and in Mode 4 within the next 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Contrary to this requirement, on November 22, 2013, PSEG identified that five of the fourteen SRVs were determined to have their as-found setpoints in excess of the TS allowable tolerance, thus leaving nine operable SRVs. The pilot assembly for each of the fourteen SRVs has been replaced with a fully tested spare assembly. Additionally, LER 2013-007 stated PSEGs proposal to replace the SRVs is being considered through the plant modification process. PSEG entered this issue into their CAP as notification 20631351. The inoperability of the five SRVs 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. Therefore, this finding is of very low (Green) safety significance based on an SDP issue screening, because the SRVs would have functioned to prevent a reactor vessel overpressurization. The closure of the LER associated with this event was documented in Section 4OA3. |
