| Title | Licensee-Identified Violation |
| Description | 10 CFR 50, Appendix B, Criterion XVI, requires that measures shall be established to assure that conditions adverse to quality ... are promptly identified and corrected. Contrary to these requirements, PSEG did not correct a condition adverse to quality identified in 2006 regarding excessive stanchion corrosion that impacted 12 SW strainer cable support capability during a seismic event until December 2010. As a result, PSEG also violated TS 3.7.4.1, Service Water System, which requires two independent SW loops to be operable. On eight separate occasions between 2007 and December 2010, a SW loop was out-of-service for greater than 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> due to SW strainer inoperability concurrent with other SW pump/strainer inoperability. PSEG entered this issue into their CAP as notification 20491305. The inspectors determined that the finding was of very low safety significance (Green) in accordance with IMC 0609, Attachment A, following a risk evaluation performed by a senior reactor analyst. That evaluation determined that, although degraded, the No. 12 SW strainer was still capable of performing its safety function during a design basis seismic event. Accordingly, full mitigation capability of the SW system was maintained during the subject period from 2007 to 2010 and, consequently, there was no increase in risk to plant operations due to the degraded SW strainer cable support condition. |
