| Title | Failure to identify a condition adverse to quality for Masterpact 600V breakers |
| Description | The inspectors identified a non-cited violation of 10 CFR 50 Appendix B, Criterion XVI, Corrective Action, for failing to identify the applicability of US NRC Part 21 Report 2016-20-01 to the 1B emergency diesel generators (EDGs) motor control center (MCC 1B). The licensee entered this issue into the corrective action program for resolution as CR 10240007. For corrective actions, the licensee performed an immediate operability determination and established compensatory measures to reset the breaker linkage in the event that it malfunctions. The performance deficiency was determined to be more than minor because it was associated with the Mitigating Systems cornerstone attribute of Equipment Performance and adversely affected the cornerstone objective of ensuring the availability, reliability, and capability of the systems that respond to initiating events to prevent undesirable consequences. The inspectors determined the finding to be of very low safety significance (Green) because the structure, system, or component maintained its operability or functionality. The finding was assigned a cross-cutting aspect of Evaluation [P.2], in the Problem Identification and Resolution area because the organization did not thoroughly evaluate the Masterpact breaker Part 21 to ensure that resolutions addressed the causes. |
