EXECUTIVE
SUMMARY
This Executive Summary summarizes the major activities that were performed for the Unit 3 Appendix R program and their association with the request for additional information from the NRC dated June 16, 1995:
1-Calculation ND-Q3999-910018 " REQUIRED MECHANICALEQUIPMENT FOR UNIT3 SAFE SHUTDOWiiP This calculation identifies the mechanical equipment that willbe required for safe shutdown ofUnit 3 and their required mode ofoperation;
~
Bases for the selection ofsafe shutdown equipment for Unit 3 are the same as they were for Unit 2.
~
The major differences are the addition ofthe RCIC system and the deletion of the DrywellTemperature Monitors.
This calculation provided input for all electrical analysis.
Item 1 ofthe NRC request ( Flow Diagrams and Control Diagrams) is direct input to the required mechanical equipment calculation.
2-Cable Block Diagrams Cable Block Diagrams are a summate ofinformation contained on cable schedules, conduit and grounding drawings, and connection diagrams.
They provided input to 2 calculations:
~
ED-Q3999-920042 "APPENDIX R - CIRCUITANALYSISOF FIRE SAFE SHUTDOWN COMPONENTS"
~
ED-Q3999-920128 "APPENDIXR - ELECTRICALCABLEFIRE AREA/ZONEROUTING" These 2 calculations are now maintained. for historical purpose.
The information is now maintained in the INDMS Database.

SUMMARY
3-Calculation ED-Q3999-940040 "APPENDIXR COMPUTERIZED SAFE SHUTDOWN SEPARATION ANALYSIS" This calculation demonstrate the availability ofthe required Appendix R components for each fire area/zone.
~
Methodology and approach different from Unit 2. More equipment was analyzed, more than 1 success path in some case was determined to be available.
~
This calculation identifies the manual action associated with Appendix R required components as a result of the separation analysis.
~
This calculation provides input to the auxiliary power system calculation.
Item 2, 3 and 4 (Plant Layout,and Equipment Location Drawings, Cable Block Diagrams and AC/DC Single Line Drawings) are direct input to the fire area analysis calculation.
4-Calculation "ED-Q0999-880489" APPENDIX R - TABULATIONOF EQUIPMENT POWER SUPPLIES ANDDETAILINGCRITERIAFOR THE AUXILIARYPOWER SYSTEM (APS)"
This calculation identifies in a diagrammatic format the portions ofthe AC and DC power systems that are required for safe shutdown. Additionallyit reviews the diesel generators loading to ensure that they stay within their rating.
~
Allthe equipment that is available is identified in the figures.
Item 4 (AC/DC Single Line Diagrams) are direct input to the APS'calculation.
5-ND-Q0999-920116 "APPENDIXR MANUALACTIONS REQUIREMENTS" This calculation identifies all the manual actions required for safe shutdown.
~
Is the primary input to the Safe Shutdown Instructions and'Calculation ND-Q0999-920115 "APPENDIXR - LOCATIONFOR EMERGENCY LIGHTING" Item 5 (APPENDIX R EMERGENCY LIGHTINGDRAWINGS) is an output to the Appendix R Location for Emergency Lighting Calculation.

SUMMARY
6-ASSOCIATED CIRCUITANALYSISFOR TYPE IANDTYPE HICIRCUITS TYPE I
~
These calculations demonstrated that selective coordination exist for all Appendix R"required power supplies.
TYPE III
~
These calculations demonstrated that all the cables that. could be routed in a common enclosure with required Appendix R cable are protected for auto-ignition.
Calculation ED-Q3999-920187 " APPENDIX R ASSOCIATED CIRCUITANALYSIS FOR SHUTDOWN COMPONENTS" provides a summary. oftype I and type IIIanalysis.
