Title | Station BLACKOUT/APPENDIX-R Diesel Generator Post Modification Test Deficiencies |
Description | The inspectors identified a Green NCV of Technical Specification 5.4.1, Administrative Controls - Procedures, because Entergy did not implement the requirements of EN-DC-117, Post Modification Testing and Special Instructions, to control revisions to the station blackout/Appendix R diesel generator (SBO/App-R DG) post modification test, or to review and approve the test results. Specifically, the SBO/App-R DG post modification test was not sufficient to demonstrate the SBO/App-R DG could perform its intended design functions. As a corrective measure, Entergy subsequently performed additional testing to demonstrate system operability. The inspectors determined 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 post modification test deficiencies represented reasonable doubt regarding the operability of the SBO/App-R DG. 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 Entergy\'s supervisory and management oversight of work activities was not adequate to ensure testing was properly performed.
