| Title | Failure to Follow Surveillance Testing Procedure |
| Description | The team identified a Green, non-cited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, which states, in part, Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Specifically, between November 5, 2010 and September 17, 2012, the licensee failed to follow Procedure 73DP-9ZZ14, Surveillance Testing, Step 3.6.1, Failed Step or Out-of-Tolerance Data, which requires personnel to write a Palo Verde Action Request (PVAR) when a failed surveillance test is encountered. On three separate occasions, the licensee failed to initiate a Palo Verde action request when the containment air lock door seal surveillance test failed. In response to this issue, the licensee confirmed that minor maintenance had been performed on the containment air lock door seals immediately following the failure of the surveillances and the surveillances then met the procedure requirements. This finding was entered into the licensees corrective action program as Palo Verde Action Requests (PVARs) 4499119 and 4499123. The team determined that the failure to follow Procedure 73DP-9ZZ14, Surveillance Testing, which required maintenance personnel to write a Palo Verde action request upon the failure of a surveillance test, was a performance deficiency. This performance deficiency was more than minor because if left uncorrected, it would lead to a more significant safety concern. Specifically, by not initiating Palo Verde action requests for failed surveillances, the licensee missed the opportunity to enter the failures into their corrective action program, perform formal operability determinations, consider the conditions for identification of maintenance rule functional failures, identify performance trends, and ultimately, correct the adverse condition in a timely manner. In accordance with Inspection Manual Chapter 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, dated June 19, 2012, Exhibit 3, Barrier Integrity Screening Questions, the issue screened as having very low safety significance (Green) because it did not represent an actual open pathway in the physical integrity of reactor containment and did not involve an actual reduction in function of hydrogen igniters in the reactor containment. This finding had a cross-cutting aspect in the area of human performance because licensee leaders failed to ensure that personnel, equipment, procedures, and other resources are available and adequate to support nuclear safety. |
