| Title | Failure to Promptly Identify a Condition Adverse to Quality for a Boric Acid Leak on 2-SMV-68-548 |
| Description | An NRC-identified NCV of very low safety significance associated with 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, was identified for the failure to promptly identify and correct a condition adverse to quality. Specifically, NRC inspectors identified a boric acid leak on the Unit 2 loop 1 hot leg sample valve, 2-SMV-68-548, that had been missed by licensee personnel performing boric acid corrosion control program walkdowns during Unit 2 refueling outage 1 (RFO1). The performance deficiency was determined to be more than minor because, if left uncorrected, it had the potential to lead to a more significant safety concern. The inspectors performed the significance determination using NRC IMC 0609. The finding affected the Barrier Integrity Cornerstone while Unit 2 was shut down, so IMC 0609 Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Initial Screening and Characterization of Findings, dated May 9, 2014, was used to determine that this finding was of very low safety significance (Green) because it did not degrade the ability to isolate a drain down or leakage path. The finding had a cross-cutting aspect in the Work Management attribute of the Human Performance area as defined in NRC IMC 0310, because the licensee did not implement a process of planning, controlling, and executing work activities such that nuclear safety is the overriding priority.
