| Title | Failure to Correct a Condition Adverse to Quality |
| Description | The NRC identified a Green non-cited violation (NCV) of 10CFR50 appendix B, Criterion XVI, for the licensees failure to correct a condition adverse to quality (CAQ) per NPG-SPP-22.302, Corrective Action Program Screening and Oversight. Specifically, in April 2013, an NRC inspector identified that a lack of a vent hole in the 2B RHR pump room flood switch housing was a deficiency previously identified in June 2005 that was not corrected for a period of over seven years. The licensee took immediate corrective action to install the required vent hole. The licensee entered the finding into their corrective action program (CAP) as PER 739142. This finding was determined to be greater than minor because it was associated with the Design Control attribute of Mitigating Systems cornerstone and adversely affected the cornerstones objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). Specifically, the finding reduced the reliability and capability of the 2B RHR pump room flood switch to perform its safety function as designed. Using IMC 0609.04, Initial Characterization of Findings and IMC 0609 Appendix A, Exhibit 4 External Events Screening Questions, the finding screened as very low safety significance (Green) because the finding did not involve the total loss of any safety function, identified by the licensee through a PRA, IPEEE, or similar analysis, that contributes to external event initiated core damage accident sequences. The cause of this finding was determined to have a cross-cutting aspect in the Problem Identification and Resolution area, Corrective Action component, and the aspect of taking appropriate corrective actions in a timely manner because corrective actions were not implemented after over seven years from discovery of the CAQ. |
