The following information was provided by The following information was provided by the licensee (licensee text in quotes):</br>On March 7, 2005, a condition assessment and resolution document was initiated to document several possible design and operating procedure deficiencies affecting Appendix R and Station Blackout (SBO) events. The deficiencies were identified during development of a proposed modification affecting existing Appendix R and SBO power supplies. On March 30, 2005, it was determined that the applicable Appendix R success criteria could not be assured under all of the postulated scenarios described in the Updated Final Safety Analysis Report (UFSAR). Specifically, during the scenarios where Combustion Turbine Generator (CTG) 11-1 (the dedicated Appendix R alternate power source) or other station CTGs are operating in parallel with the grid, availability of the alternate power source under Appendix R and SBO scenarios cannot be assured. Therefore, this event is being reported under 50.72(b)(3)(ii)(B). Actions to address the potentially affected Appendix R and SBO scenarios were put in place on March 7, 2005, when the deficiencies were identified. The NRC Resident Inspector has been notified.
