| Title | Failure to Identify and Correct a Condition Adverse to Quality Associated with Safety Relief Valve Discharge Piping Misalignment |
| Description | A self-revealing Green non-cited violation (NCV) of Title 10 of the Code of Federal Regulations Part 50 (10 CFR) Part 50, Appendix B, Criterion XVI, Corrective Action, was identified when PSEG did not promptly identify and correct a condition adverse to quality. Specifically, PSEG did not initiate a notification (NOTF) or perform an evaluation of a potential cold spring condition found in the H safety relief valve (SRV) discharge piping during the valves replacement in 2012. This condition caused a leak to develop on the main seat of the new SRV that proceeded to degrade during the operating cycle, ultimately causing Hope Creek to shut down on September 5, 2014. PSEGs corrective actions included replacing the H SRV, providing training to all maintenance crews responsible for SRV work, and adding steps to the SRV removal and installation procedure to: 1) generate a notification for the identification of any piping misalignment; and 2) pin the discharge piping spring can prior to SRV removal. The finding was more than minor because it was associated with the procedure quality attribute of the Initiating Events cornerstone and adversely affected the cornerstone objective to limit the likelihood of an event that upsets plant stability. Also, if left uncorrected, the performance deficiency had the potential to lead to a more significant safety concern. The inspectors determined that this finding was of very low safety significance (Green) using Exhibit 1 of IMC 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, because the finding did not cause both a reactor trip and the loss of mitigation equipment relied upon to transition the plant from the onset of the trip to a stable shutdown condition. This finding has a cross-cutting aspect in the area of Problem Identification and Resolution, Identification, because PSEG did not identify this issue completely, accurately, and in a timely manner in accordance with the corrective action program (CAP). |
