on O to Appendix A of this SRP section do not apply to operating reactors as a backfit item. Operating reactors which install generator circuit breakers or load break switches to meet the requirements of GDC 17 after July, 1983 must meet guidelines 1 through 4 of this appendix. 2. Guidelines 1 through 4 of Revision O to Appendix A of this SRP section have already been imposed (as applicable) on Operating License application reviews for which a Safety Evaluation Report has been issued but have not received their full power license as of yet. 3. Guidelines 1 through 4 of Revision O to Appendix A of this SRP section are applied to all current and future OL and CP application reviews (as applicable). D. References 1.

DRAFT Rev. 4 - April 1996 8.2-22 APPENDIX B to SRP Section 8.2 GUIDELINES FOR REVIEW OF ALTERNATE AC SOURCES FOR STATION BLACKOUT AT NUCLEAR POWER PLANTS118 A. Background The term "station blackout" refers to the complete loss of alternating current electric power to the essential and nonessential switchgear buses in a nuclear power plant. Station blackout therefore involves the loss of offsite power concurrent with turbine trip and failure of the onsite emergency ac power system, but not the loss of available ac power to buses fed by station batteries through inverters or the loss of power from
