| Title | Failure to Account for Plant-Specific Maintenance History in the Development of Preventive Maintenance Frequency |
| Description | The inspectors identified a finding of very low safety significance and an associated non-cited violation of 10 CFR Part 50, Appendix B, Criterion V for the licensees failure to follow procedure FP-PE- 90-01, Preventive Maintenance Program. Specifically, in 2009, when setting the preventive maintenance frequency for containment isolation valve 1MS-02083, t he licensee determined that a 15-year frequency was appropriate instead of the recommended 10 years. The licensees justification was based on internal maintenance history showing good performance. However, the inspectors review revealed that the maintenance history for this category of valves did not support this determination. The valve subsequently failed during surveillance on March 21, 2013, after 13 years of service. The licensee entered this issue into the CAP as AR01858451; corrective actions included replacing the valve and an action to review the preventive maintenance frequencies of critical solenoid-operated valves. The inspectors determined that the finding was more than minor in accordance with IMC 0612, Appendix B, because it was associated with the Barrier Performance attribute of the Barrier Integrity Cornerstone, and adversely affected the Cornerstone objective to provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events. The inspectors evaluated this finding using IMC 0609, Appendix G, Shutdown Operations Significance Determination Process, Checklist 3, and determined that the finding was of very low safety significance because the inspectors determined that a quantitative assessment was not required. The inspectors did not identify a cross-cutting aspect associated with this finding because the finding did not reflect current performance due to the age of the performance deficiency. |
