| Title | Failure To Identify A Condition Adverse To Quality |
| Description | The NRC identified a Green NCV of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to identify and correct a Condition Adverse to Quality (CAQ). Specifically, the licensee failed to capture in the CAP a concern with the potential corrosion of magnesium motor rotor fan blades associated with safety-related motor operated valves (MOVs). The MOVs were associated with the reactor recirculation and residual heat removal (specifically the low pressure core injection mode) systems. The concern was identified during an internal licensee review of OE. The failure to capture this item in the CAP resulted in the licensee not being able to utilize the CAP process to ensure that the CAQ had been properly evaluated and corrected. This finding has an associated cross-cutting aspect associated in the area of PI&R, Corrective Action Program for the failure to properly evaluate the potential impact of the CAQ on the affected, safety-related MOVs. [P.1(C)] The finding is more than minor because it directly affected the Human Performance attribute of the Initiating Events Cornerstone objective to limit the likelihood of events that upset plant stability and challenge critical safety functions while at power. The finding also directly affected the Equipment Performance attribute of the Mitigating System Cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences (i.e., core damage). The finding is of very low safety significance, because the issue only involved the potential degradation, but not the actual loss of a plant component (i.e., there was no actual initiating event nor loss of a mitigating system).
