| Title | Repetitive Failure to Enter Technical Specifications for Auxiliary Feedwater Suction Valve Testing |
| Description | The inspectors identified a noncited violation of Technical Specification 5.4.1.a, Procedures, involving the failure to follow Procedure AP 21-001, Conduct of Operations. Specifically, the licensee failed to enter into technical specification limiting condition of operation 3.7.5.B.1 for one auxiliary feedwater pump inoperable during performance of 92-day check valve surveillance tests. Wolf Creek took prompt corrective action to amend the procedures to include instructions for maintaining the pumps operable with manual actions. This occurred prior to the next check valve test. This issue is captured in Condition Report 34469. The failure to enter technical specification action statements in accordance with Procedure AP 21-001 was a performance deficiency. The performance deficiency was more than minor, and therefore a finding, because it impacted with the human performance attribute of the Mitigating Systems Cornerstone and its objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. Using Inspection Manual Chapter 0609.04, Phase 1 Initial Screening and Characterization of Findings, the finding was determined to be of very low safety significance (Green) because the issue did not result in a loss of operability for a time period greater than the action statement, and did it not screen as potentially risk significant due to a seismic, flooding, or severe weather initiating event. The inspectors determined that the finding has a crosscutting aspect in the area of human performance associated with decision making. Specifically, informally maintained pre-job briefing sheets were being relied upon to determine technical specification applicability instead of the licensees decision making process of operator review on a case by case basis H.1.a. (Section 1R22). |
