| Title | Failure to Establish Preventative Maintenance Schedules for Fuel Oil Tank Vents |
| Description | The inspectors identified a non-cited violation of Technical Specification 5.4.1.a, Procedures, for the licensees failure to establish preventative maintenance schedules for the emergency diesel generator fuel oil storage and day tank flame arrestor vents. A misclassification of these vents as run-to-maintenance components resulted in the failure to establish preventative maintenance schedules. In response, the licensee initiated AR 314568314568to re-evaluate the maintenance classification of the diesel fuel oil storage tank flame arrestor vents and establish preventative maintenance tasks for those components. This performance deficiency was more than minor because it was associated with the procedure quality attribute of the Mitigating System cornerstone and affected the cornerstones objective to ensure the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors performed an initial screening of the finding in accordance with NRC Manual Chapter IMC 0609, Appendix A, The Significance Determination Process for Findings At-Power. Using IMC 0609, Appendix A, Exhibit 2, Mitigating Systems Screening Questions, the inspectors determined this finding is of very low safety significance (Green) because the finding was a design or qualification where the system maintained its operability. Because the cause of this finding was that the licensee had misclassified the maintenance requirements for the flame arrestor vents upon installation, it is not reflective of current performance and no cross-cutting aspect is assigned. |
