| Title | Inadequate MOV Program Implementation |
| Description | The inspectors identified a Green NCV of 10 CFR Part 50 Appendix B, Criterion V, Instructions, Procedures, and Drawings, regarding PPLs safety-related motor operated valve (MOV) program. Specifically, the program lacked a procedure, qualification, and prescribed acceptance criteria for actuator grease analysis and PPL improperly implemented maintenance instructions for lubricating valve stems. PPLs QA organization conducted a separate investigation and entered this issue in their CAP via CRs 1545581 and 1544737. This finding was considered more than minor because it was similar to IMC 0612, Appendix E, examples 3.j and 3.k, in that significant programmatic deficiencies existed that could lead to worse errors if uncorrected. The lack of a procedure, repeatable acceptance criteria, qualification, and multiple cycles without stem lubrication could result in untimely actuator overhauls and ultimately MOV degraded performance. Further, the performance deficiency affected the equipment 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. Specifically, inadequate MOV program implementation affects MOV reliability. The issue screened to Green via IMC 0609 Attachment 4 since it was not a design or qualification deficiency or loss of safety function and did not screen as potentially risk significant due to external events. The issue was determined to have a cross-cutting aspect in the area of Problem Identification and Resolution. In this case, PPL was aware of the lack of procedural guidance and qualification for MOV grease analysis as well as non-compliance with stem lubrication instructions but had not entered the concerns in its CAP. |
