Title | Failure to Update an Operability Evaluation |
Description | The inspectors identified a noncited violation of 10 CFR Part 50, Appendix B, Criterion V, Instructions, Procedures and Drawings, for the failure to implement Procedure AP 26C-004, Technical Specification Operability, Revision 20, to adequately evaluate the operability of a degraded essential service water system. Specifically, operations and engineering personnel failed to adequately evaluate the operability of the essential service water system when relevant new information was identified that challenged a previously performed operability determination and which challenged the reasonable expectation for operability. Condition Report 27288 was initiated to evaluate the failure to perform adequate operability determinations.
The issue was more than minor because if left uncorrected, it would have the potential to lead to a more significant safety concern. The finding is associated with the Mitigating Systems Cornerstone. 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. The inspectors determined that the cause of the finding has a crosscutting aspect in the area of human performance associated with resources because the licensee failed to provide complete, accurate, and up-to-date procedures for performing operability evaluations H.2(c) |
