| Title | Failure to Identify Foreign Material in the Reactor Core |
| Description | A self-revealing noncited violation of Technical Specification 5.4.1.a was identified regarding the licensees failure to follow the requirements of System Operating Procedure 2.2.18, 4160V Auxiliary Power Distribution System. Specifically, operators preparing the 4160 F bus for a maintenance outage secured the wrong fuel pool cooling pump. When the bus was subsequently deenergized, a loss of fuel pool cooling occurred. The licensee entered this issue in their corrective action program as CR-CNS-2009-07770. The finding is more than minor because it is associated with barrier integrity cornerstone attribute of configuration control, and adversely affected the cornerstone objective of maintaining functionality of the spent fuel pool cooling system to provide reasonable assurance that the fuel cladding physical design barrier protects the public from radionuclide releases caused by accidents or events. Because the plant was shutdown at the time this performance deficiency occurred, the inspectors used Manual Chapter 0609, Appendix G, Shutdown Operations Significance Determination Process. Using Checklist 7 in Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Operational Checklists For Both PWRs and BWRs, the inspectors determined that the finding had very low safety significance because every item on the checklist was met. The finding has a crosscutting aspect in the area of human performance associated with work practices because the licensee failed to effectively use required self-checking error prevention tools H.4(a) |
