An NRC identified NCV of 10 CFR Part 50, A … An NRC identified NCV of 10 CFR Part 50, Appendix B, Criterion XVI was identified for the licensee's failure to establish measures to promptly identify a condition adverse to quality involving the malfunction of the High Pressure Coolant Injection (HPCI) turbine exhaust system. Upon discovery of the malfunction, the licensee took action to determine that HPCI remained operable despite the degraded and nonconforming condition. The licensee is developing corrective actions to resolve the degraded and nonconforming condition. The licensee entered the violation into the licensee's corrective action program as CR 1098320. The performance deficiency was more-than-minor because it was associated with the Equipment Performance attribute of the Mitigating Systems cornerstone and it adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e. core damage). Specifically, the performance deficiency resulted in the HPCI system being operated with an unidentified degraded/non-conforming condition which degraded the system capability and challenged system operabilty. The inspectors determined the finding was Green because the finding was a deficiency affecting the qualification of HPCI, but based on the licensees evaluations, operability was maintained. The inspectors determined that the finding had a cross-cutting aspect in the Problem Identification and Resolution area of Evaluation (P.2), because the licensee did not thoroughly evaluate an abnormal system condition to ensure that resolutions addressed causes commensurate with their safety significance.mmensurate with their safety significance. +
