| Title | Failure to Identify and Correct Test Procedures to Assess the As-Found Trip Setpoint for Pressure Switches that Satisfy Technical Specification Functions |
| Description | The inspectors identified a finding of very low safety significance (Green) and associated NCV of 10 CFR 50, Appendix B, Criterion XVI, Corrective Action, for the licensees failure to assure that conditions adverse to quality associated with preconditioning were promptly identified and corrected. The licensees corrective actions included actions for Engineering to evaluate all the Technical Specification functions that do not have test valves installed on their pressure switches and justify the potential unacceptable preconditioning as acceptable or take other actions as appropriate. The licensee entered this finding into the corrective action program as issue report (IR) 1120159. The finding was determined to be more than minor because it impacted the Mitigating Systems Cornerstone objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors did not identify any cross-cutting aspect associated with this finding. The inspectors evaluated the finding using IMC 0609, Significance Determination Process, Attachment 4, Phase 1 Initial Screening and Characterization of Findings. The inspectors answered No to all questions in the Mitigation System Cornerstone column of Table 4a, Characterization Worksheet for IE, MS, and BI Cornerstones, therefore, the finding screened as Green (very low safety significance). |
