| Title | Operating Personnel Incorrectly Placed Clearance Tags |
| Description | A finding of very low safety significance and associated NCV of Technical Specification 5.4.1 was self-revealed for the failure to meet the requirements of Clearance Order (CO) 69631 by removing shorting links instead of fuses as required by the CO on November 12, 2009. As a result, protective relaying was unintentially removed from the Unit 2 main power transformer TR-2, the unit auxiliary transformer TR-21, and the reserve auxiliary transformer TR-22. This issue was entered into the licensees CAP as Issue Report 992290. Corrective actions included: coaching of the individuals involved with the incorrect placing of the out-of-service and a placard on the device that was incorrectly repositioned was changed to include the specific equipment part number of the shorting links. The finding was determined to be more than minor because the finding could reasonably be viewed as a precursor to a significant event. The finding was evaluated using the SDP in accordance with IMC 0609, Appendix G, Attachment 1, Shutdown Operations Significance Determination Process Phase 1 Operational Checklists For Both PWRs and BWRs, Checklist 6, dated May 25, 2004. This checklist stated that for a finding to require a Phase 2 or 3 determination, it would require an increase in the likelihood of a loss of offsite power or degrade the licensees ability to cope with a loss of offsite power. The ability of the licensee to cope with a loss of offsite power was not impacted because at least one emergency diesel generator was operable during the entire period. The inspectors determined that neither of these conditions were met so the finding screened as Green. This finding had a cross-cutting aspect in the area of Human Performance, Work Practices. H.4(a |
