| Title | Failure to Properly Assess Problems with Component Cooling Water Valve EGHV102 |
| Description | The team identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion XVI, Corrective Action, which states, in part, Measures shall be established to assure that conditions adverse to quality, such as failures, malfunctions, deficiencies, defective materials and equipment, and nonconformance are promptly identified and corrected. Specifically, in April 2011 and November, 2012, the licensee failed to properly categorize Condition Reports CR-37825 and CR-60298 correctly, which resulted in the condition reports not getting an Apparent Cause Evaluation, to promptly identify and correct the cause of the Component Cooling Water Butterfly Valve EGHV0102 loose disc to shaft, failure of the groove pin in the valve, and to investigate the extent of condition for similar valves currently installed in the plant. The licensee has entered this issue into their corrective action program as Condition Report CR-73227. The team determined the licensees failure to follow the Corrective Action Procedure AI 28A-010, Screening Condition Reports, which improperly categorized Condition Reports CR-37825 and CR-60298, which should have had apparent cause evaluations performed, was a performance deficiency. This finding was more than minor because it adversely affected the Equipment Performance attribute of the Mitigating Systems Cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Specifically, the failure to perform an apparent cause evaluation resulted in the licensee not identifying a root cause for the valve leakage, preventing reoccurrence, or investigating the extent of condition for other similar valves installed in the plant. In accordance with NRC Inspection Manual Chapter 0609, Appendix A, Exhibit 2, the inspectors determined the finding was of very low safety significance (Green), because the finding was not a design deficiency and did not result in the loss of operability or functionality. This finding had a cross-cutting aspect in the area of Human Performance, associated with Work Practices. Specifically the licensee defines and effectively communicates expectations regarding procedural compliance and personnel follow procedures. |
