| Title | Failure to Demonstrate the Performance of the Diesel Air Compressor was Being Effectively Controlled Through Preventive Maintenance |
| Description | The inspectors identified an NCV of 10 CFR 50.65, Maintenance Rule (MR), paragraph (a)(2), when Ginna did not demonstrate that the performance of the diesel-driven service air compressor was being effectively controlled through preventive maintenance. Specifically, Ginna did not fully evaluate whether failures of the diesel-driven air compressor that occurred in October 2006 justified monitoring under paragraph (a)(1) of the Maintenance Rule (MR). Ginna reassessed the October events and determined that both events were functional failures and one event was a maintenance preventable functional failure. Ginna subsequently determined that the air compressor should have been placed in category (a)(1) of the MR as specified by 10 CFR 50.65. Ginna\'s corrective actions included modifying procedures to identify the operations department as the responsible department for maintaining fuel level in the compressor, establishing a monitoring frequency for fuel level, and providing direction for refueling the compressor. Additional corrective actions included documenting and monitoring the compressor run times to ensure the fuel filter replacement frequency of 250 hours0.00289 days <br />0.0694 hours <br />4.133598e-4 weeks <br />9.5125e-5 months <br /> is not exceeded. This finding is more than minor because it is associated with the Mitigating Systems Cornerstone and affected the cornerstone objective of ensuring the availability, reliability, and capability of systems that respond to initiating events to prevent undesirable consequences (Le., core damage). The inspectors determined the finding was of very low safety significance (Green) using Inspection Manual Chapter (IMC) 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations. Specifically, the finding was not a design or qualification deficiency, did not represent a loss of safety function, and did not screen as potentially risk significant due to seismic, flooding, or severe weather. Since this performance deficiency occurred in 2006 and does not reflect current performance, no cross-cutting aspect was assigned. |
