| Title | Failure to Determine if a Deficiency Existed in the Ultimate Heat Sink |
| Description | The team identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, for the failure to follow the requirements of Procedure AP 26C-004, Technical Specification Operability, Revision 20. Specifically, Wolf Creek Generating Station failed to confirm if a deficiency existed with the ability of the ultimate heat sink to perform its safety function after delaying the 5-year scheduled dredging of the channel. The licensee initiated Condition Report 27080 and performed an operability determination to evaluate the deficiency.
The issue 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. Using Inspection Manual Chapter 0609, the issue is determined to have very low safety significance because the finding is not a design or qualification issue confirmed not to result in a loss of operability or functionality; did not represent an actual loss of safety function of the system or train; did not result in the loss of one or more trains of nontechnical specification equipment; and did not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. This finding has a crosscutting aspect in the area of problem identification and resolution associated with the corrective action program component because licensee personnel failed to identify a potential deficiency in the ultimate heat sink in a timely manner P.1(a) |
