| Title | Inoperable Containment Cooler Condensate Monitoring System |
| Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion III, due to all containment cooler drip pans being degraded such that the containment cooler condensate monitoring system could not perform its design basis safety function to quantify reactor coolant system leakage into the containment atmosphere. Wolf Creek initiated Condition Report 24005 and Work Order 10-325741-000 to clean and repair the drip pans. This issue is more than minor because it was associated with the equipment performance aspect of the Barrier Integrity Cornerstone and impacted the cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. Specifically, it affected the licensees ability to detect a reactor coolant system leak. The inspectors used Inspection Manual Chapter 0609.04, Phase 1 - Initial Screening and Characterization of Findings, to analyze the significance of this finding. The inspectors concluded the finding is of very low safety significance because the condition was not related to pressurized thermal shock. The inspectors also determined that the cause of the finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program because Wolf Creek failed to identify adverse postwork conditions after the coolers received maintenance in the 2009 refueling outag |
