| Title | Failure to Correctly Screen Essential Service Water Piping Leaks for Significance |
| Description | The team identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, regarding the licensees failure to follow the requirements of Procedure AI 28A-010, Screening Condition Reports. Specifically, licensee personnel failed to properly screen condition reports for the essential service water system adverse conditions of internal corrosion and loss of offsite power induced system pressure transient since April 2008. The adverse conditions met the procedures definitions to require a root cause analysis prior to September 2009, but none was performed. The licensee entered this deficiency in their corrective action program as Wolf Creek Condition Report 00022239.This finding is greater than minor because, if left uncorrected, the failure to fully utilize the corrective action program could become a more significant safety concern. The inspectors determined that this finding impacted the Mitigating Systems Cornerstone. Using Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the issue screened as having very low safety significance because it was not a design or qualification deficiency that resulted in a loss of operability or functionality, did not create a loss of system safety function of a single train for greater than the technical specification allowed outage times, and did not affect seismic, flooding, or severe weather initiating events. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program because licensee personnel failed to thoroughly evaluate problems such that the resolutions address causes and extent of conditions P.1(c |
