| Title | Failure to Correct Condition with ESW LOOPILOA Timer |
| Description | The inspectors identified a Green NCV of 10 CFR 50, Appendix B, Criterion XVI, \\\"Corrective Action,\\\" in that PPL failed to correct a condition adverse to quality in a timely manner. Specifically, PPL failed to replace the emergency service water (ESW) pump electropneumatic time delay relays with a design that would comply with design analysis and Technical Specification (TS) criteria. PPL entered the issue into their corrective action program CAP. This finding is more than minor because it affected the equipment performance attribute of the Mitigating System cornerstone and the associated cornerstone objective of ensuring the reliability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the finding in accordance with IMC 0609 Attachment 4, Phase 1 - \\\"Initial Screening and Characterization of Findings,\\\" Table 4a. This finding was of very low safety significance because it did not represent an actual loss of safety function. The finding had a cross-cutting aspect in the area of Problem Identification and Resolution, Corrective Action Program, because PPL did not take appropriate corrective actions to address an adverse trend in a timely manner (P.1 (d)). Specifically, PPL had a history of sequence timer failures without corrective actions to ensure TS criteria and design analysis compliance for a full testing interval. |
