In Modes 1, 2, and 3, Hope Creek TS 3.4.2. … 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 +/-3 percent of the specified code safety valve function lift settings or else be in Mode 3 within 12 hours and in Mode 4 within the next 24 hours. Contrary to this requirement, between May 10 and May 11, 2011, PSEG identified that six of the 14 SRVs were determined to have their as-found setpoints in excess of the TS allowable tolerance, thus leaving eight operable SRVs. The pilot assembly for each of the 14 SRVs was replaced with a fully tested spare assembly. Additionally, LER 05000354/2012-004-00 stated PSEGs proposal to replace the SRVs is being considered through the plant modification process. PSEG entered this issue into their corrective action program as notification 20559112. The finding documents the inoperability of six SRVs that 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 safety significance (Green) based on a SDP issue screening, because the SRVs would have functioned to prevent a reactor vessel over-pressurization.
