| Title | Unacceptable preconditiong of control rods prior to surveillance testing |
| Description | On February 6, 2009, the inspectors identified a noncited violation of 10 CFR 50 Appendix B, Criterion XI, Test Control for a procedure that allowed unacceptable preconditioning of the control rods prior to Technical Specification Surveillance 3.1.4.2. Wolf Creek did not perform any preconditioning acceptability review when adopting operating experience and revising Procedure STS SF-001. The licensee entered this issue into their corrective action programs as Condition Report 2009-00598. Unacceptable preconditioning of the control rods is a performance deficiency. The finding was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone, and it affected the cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors evaluated the significance of this finding under the mitigating systems cornerstone using Phase 1 of Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, and determined that the finding was of very low safety significance (Green) because, it did not represent an actual loss of safety function and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding was determined to have a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program because the condition report that adopted the operating experience failed to evaluate NRC guidance regarding preconditioning during surveillance testing which should have disallowed the procedure change. Therefore, the applicable procedures were not complete and accurate P.1(c) (Section 1R22) |
