| Title | Failure to Identify a Condition Adverse to Quality for the Control Room Envelope |
| Description | The inspectors identified a Green non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, involving the licensees failure to promptly identify and correct a condition adverse to quality. Specifically, following the identification of general corrosion on the Units 1 and 2 control room envelope heating, ventilation, and air conditioning ducts, the licensee failed to identify that moisture condensing and collecting was a condition adverse to quality and failed to correct the condition. As a result, corrosion caused through-wall leaks in 2008 and 2014. The licensee entered this into the corrective action program as Condition Report 14-17723, and planned to evaluate and address the issue. The failure to promptly identify and correct a condition adverse to quality is a performance deficiency. The performance deficiency was more than minor because it is associated with the barrier performance attribute of the Barrier Integrity Cornerstone and affected the cornerstone objective. Using NRC Inspection Manual Chapter 0609, Appendix A, Significance Determination Process (SDP) for Findings at Power, dated June 19, 2012, the finding was determined to be of very low safety significance (Green) because the finding only represented a degradation of the radiological barrier function provided for the control room. The finding has a cross-cutting aspect in the area of problem identification and resolution associated with evaluation, because the licensee failed to thoroughly evaluate the issue to ensure that the resolution addressed the cause of extent of condition commensurate with the safety significance. |
