| Title | 13 Service Water Strainer Unavailablility Due To Inadequate Post Maintenance Test |
| Description | A self-revealing non-cited violation (NCV) of Technical Specification (TS) 6.8.1.a Procedures and Programs, was identified because the 13 service water (SW) strainer failed while in-service on March 13, 2012. PSEG failed to perform adequate post-maintenance testing (PMT) on the 13 SW strainer before declaring it operable on January 13, 2012, and therefore did not find inadequate clearance between the strainer drum and body. This issue was entered into PSEGs corrective action program (CAP) as notification 20550115. PSEGs immediate corrective actions were to replace the strainer drum o-ring, adjust the strainer clearances and perform a PMT of the strainer. The inspectors determined that the performance deficiency was more than minor because it was associated with the human performance attribute of the Mitigating Systems cornerstone, and it adversely affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the trip of the 13 SW strainer while the 14 SW pump was inoperable for planned maintenance resulted in Salem Unit 1 entering a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> unplanned limiting condition for operation (LCO) for 11.5 hours5.787037e-5 days <br />0.00139 hours <br />8.267196e-6 weeks <br />1.9025e-6 months <br />. The finding was evaluated in accordance with IMC 0609, Attachment 4, Initial Screening and Characterization of Findings, and was determined to require additional evaluation. The finding was subsequently evaluated in IMC 0609, Phase 3 utilizing the NRCs SAPHIRE 8 risk analysis SDP interface tool using the Salem specific standardized plant analysis review (SPAR) model, and confirmed to be of very low safety significance. This finding has a cross-cutting aspect in the area of human performance, work practices, because PSEG personnel did not follow procedures. Specifically, PSEG personnel failed to comply with procedure Service Water Auto Strainer Adjustment, Inspection, Repair and Replacement, which required an evaluation of a torque curve generated by a baker box. |
