| Title | Licensee-Identified Violation |
| Description | Title 10 of the Code of Federal Regulations (10 CFR), Part 50, Appendix B, Criterion XVI, Corrective Actions, requires measures to be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, deviations, defective material and equipment, and nonconformances are promptly identified and corrected. Contrary to 10 CFR 50, Appendix B, Criterion XVI, station personnel did not promptly correct a condition adverse to quality. Specifically, from August 1, 2013 to February 26, 2016, Talen did not implement corrective actions to establish a PM program for molded case circuit breakers (MCCBs) found in distribution control panels that protect containment penetration conductors. The need for a MCCB PM program was originally identified during the 2013 NRC CDBI and documented as NCV 05000387 (05000388)/2013010-01, Failure to Verify Operation of Safety-Related 125Vdc Molded Case Circuit Breakers (CR 1732454). Talen identified this untimely implementation of corrective action during a self-assessment in preparation for the 2016 NRC CDBI. Plant staff entered the issue into the corrective action program (CRs 2016-04833; 23373; 23971 and 24015) and established a MCCB PM program. The team evaluated this finding using IMC 0609.04, Initial Characterization of Findings, and IMC 0609, Appendix A, Exhibit 3, Barrier Integrity Screening Questions. The team determined that the finding was of very low safety significance (Green) because the finding did not represent an actual open pathway in the physical integrity of reactor containment (valves, airlocks, etc.), containment isolation system (logic and instrumentation), and heat removal components, and did not involve an actual reduction in function of hydrogen igniters in the reactor containment. |
