| Title | Procedure Violation Results in Exceeding Allowed Injection Pressure (Section 1R18) |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, when maintenance personnel exceeded the specified leak injection pressure by 900 psig. Specifically, on March 7, 2009, contract maintenance personnel failed to follow Temporary Configuration Change 4686707, Leak Repair of RF-V-747 with Sealant, instructions by using an injection pressure of 4000 psig, instead of the specified injection pressure of 3100 psig for the leak injection repair of RF-V-747, the Reactor Feed Line B drywell vent shutoff valve. The licensee entered this issue into the corrective action program as Condition Report CR-CNS-2009-01874. The finding was more than minor because if left uncorrected the performance deficiency could have the potential to lead to a more significant safety concern. In accordance with NRC Inspection Manual Chapter 0609, Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Operational Checklists for Both PWRs [Pressurized Water Reactors] and BWRs [Boiling Water Reactors], the inspectors evaluated the significance of this finding. The inspectors determined that Checklist 7, BWR Refueling Operation with Reactor Coolant System Level > 23 Feet, was applicable. The finding was determined to have very low safety significance (Green) because it did not increase the likelihood of a loss of reactor coolant system inventory, did not affect the licensees ability to terminate a leak path or add inventory to the reactor coolant system, or degrade the licensees ability to recover decay heat removal in the event it was lost. The cause of this finding was related to the human performance aspect of work practices because the licensee failed to ensure adequate supervisory oversight of contractors such that nuclear safety was supported H.4(c) (Section 1R18) |
