| Title | Inadequate Operating Procedure for Station BLACKOUT/APPENDIX-R Diesel Generator |
| Description | The inspectors identified a Green NCV of Technical Specification 5.4.1, Administrative Controls - Procedures, because the SBO/App-R DG operating procedure 2-SOP-27.6, Appendix-R Diesel Generator Operation, was not adequate. Specifically, the procedure could not be performed as written, and was not sufficient to ensure operators could start the SBO/App-R DG, and energize an electrical bus within the required time of one hour. Entergy subsequently revised the procedure to correct the most critical deficiencies, and pre-staged equipment to reduce the time needed to energize a bus. As an interim corrective measure, Entergy relied upon operator training for other deficiencies, pending final corrective actions. The finding was more than minor because it was associated with the procedure quality attribute of 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. Specifically, the procedure deficiencies resulted in a reasonable doubt whether the SBO/App-R DG could be started and aligned in a timely and correct manner, as required by design. The inspectors evaluated this finding using the Phase 1 analysis in IMC 0609, Appendix A, Determining the Significance of Reactor Inspection Findings for At-Power Situations. The inspectors determined that this finding was of very low safety significance (Green) because it was not a design or qualification deficiency; it did not represent a loss of system safety function of a single train; and it did not screen as potentially risk significant due to external events. The finding had a cross-cutting aspect in the area of human performance because Entergys procedure for the SBO/App-R DG was not adequate to assure nuclear safety in implementing necessary operator actions for a SBO.
