Title | Inadequate Foreign Material Exclusion Controls Associated with Work on Emergency Diesel Generators |
Description | A finding of very low safety significance and a non-cited violation of 10 CFR Part 50, Appendix B, Criterion V was identified by the inspectors on March 15, 2010, due to the licensees failure to have instructions and procedures appropriate to the circumstance for performing Work Order 382152 and Surveillance Procedure 1295, D1 Diesel Generator 6 Month Fast Start Test. The failure to have instructions and procedures appropriate to the circumstance resulted in rendering the D1 diesel generator inoperable for 28 hours3.240741e-4 days <br />0.00778 hours <br />4.62963e-5 weeks <br />1.0654e-5 months <br /> due to the introduction of foreign material into the lube oil sump during oil addition activities. Corrective actions included retrieving the hose and nozzle, replacing the plastic oil cans with new solid metal cans, and revising the pre-job brief instructions and Are You Ready checklist to include a question whether foreign material will be generated through the use of portable equipment or tools. The inspectors determined that the finding was more than minor because it was associated with the procedure quality and human performance attributes of the Mitigating Systems Cornerstone and impacted the cornerstone objective of ensuring the availability, reliability and capability of systems that respond to initiating events to prevent undesirable consequences. The inspectors determined that this finding was of very low safety significance because it did not represent a loss of a system safety function and the diesel generator was inoperable for less than the Technical Specification allowed outage time. This finding was determined to be cross-cutting in the Human Performance, Work Control area because the licensee failed to appropriately plan work activities by incorporating job site conditions which may impact plant structures, systems, or components (H.3(a)).
