| Title | Failure to Implement Containment Closure Procedure |
| Description | The inspectors identified a Green noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure of operations personnel to fully implement a station procedure to control obstructions in primary containment openings in Modes 4 and 5. The failure to follow procedure challenged the licensees ability to establish containment closure. The licensee entered this issue into their corrective action program as Condition Report CR-RBS-2009-4296. The failure to implement the containment closure procedure is a performance deficiency. This finding is more than minor because it affected the configuration control attribute of the barrier integrity objective to provide reasonable assurance that the physical design barriers (containment) will protect the public from radionuclide releases. Using Inspection Manual Chapter 0609, Appendix H, Containment Integrity Significance Determination Process, the finding was assessed as a Type B finding because it is related to a degraded condition that has potentially important implications for the integrity of the containment without affecting the likelihood of core damage and was of very low significance because the licensee did not lose the capability to close containment when planned. The finding has a crosscutting aspect in the area of human performance, work control, because the licensee failed to appropriately coordinate work activities (identifying cables, quick disconnects, removing unidentified cables) to address the operational impact of those work activities on containment operability H.3(b). |
