Title | Failure to Appropriately Identify and Implement Adequate Corrective Actions to Correct a Condition Adverse to Quality Associated with the Material Control System |
Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion XV, Nonconforming Materials, Parts, or Components, associated with the licensees failure to properly control nonconforming components. Specifically, in 1997 the licensee identified that two check valves, which had been installed in the postaccident monitoring system, had a defective design that prevented them from seating all of the way. However, the stations material control system was not updated with this information and this model valve was subsequently issued for use in the high pressure safety injection pressurization system which resulted in leakage due to the valves failure to completely seat. The licensee entered this issue into their corrective action program as Condition Report CR-ANO-2-2009-1012. The performance deficiency was more than minor because it affected the design control attribute of the Barrier Integrity Cornerstone and it directly affected the cornerstone objective to provide reasonable assurance that the physical design barriers protect the public from radionuclide releases caused by accidents or events. Using Inspection Manual Chapter 0609, Signifiance Determination Process, Phase 1 Worksheet, this finding was determined to have very low safety significance because the finding did not represent a degradation of the barrier functions of the control room or auxiliary building, did not represent an actual open pathway in the physical integrity of reactor containment, and did not involve an action reduction in the function of hydrogen ignitors in the reactor containment. The finding was determined to have a crosscutting aspect in the area of Problem Identification and Resolution associated with the Corrective Action Program P.1(c), in that the licensee failed to thoroughly evaluate problems such that the resolutions address causes and extent of conditions as necessary. This is indicative of current plant performance because the licensee continues to inadequately evaluate issues and develop appropriate resolution |
