3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1. 3/4.8.2 and 3/4.8.3 A.C. SOURCES. D.C. SOURCES. and ONSITE POWER DISTRIBUTION The OPERABILITY of the A.C. and D.C power sources and associated distribution systems during operation ensures that sufficient power will be available to supply the safety-related equipment required for: (1) the safe shutdown of the facility, and (2) the mitigation and control of accident condi-tions within the facility. The minimum specified independent and redundant A.C. and D.C. power sources and-distribution systems satisfy the requirements of General Design Criterion 17 of Appendix A to 10 CFR Part 50.
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERASILITY of the power sources are consistent with the initial condition assumptions of the safety analyses and are based upon maintaining at least one redundant set of onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss-of-offsite power and single failure of the other onsite A.C. source. The A.C. and D.C. source allowable out-of-service times are based on Regulatory Guide 1.93, " Availability of Electrical Power Sources," December 1974. When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components and devices, that depend on the remaining OPERABLE diesel generator as a source of emergency power, are also OPERABLE, and that the diesel-driven auxiliary feedwater pump is OPERABLE.
This requirement is intended to provide assurance that a loss-of-offsite power event will not result in a complete loss of safety function of critical systems during the period one_ of the diesel generators is inoperable. The term verify as used in this context means to administrative 1y check by examining logs or other information to determine if certain components are out-of-service for maintenance or other reasons.
It does not mean to perform the Surveillance Requirements needed to demonstrate the OPERABILITY of the component.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that:
(1) the facility can be maintained in the shutdown or refueling condition for extended time periods, and (2) sufficient instrumentation and control capability is available for monitoring and maintaining the unit status.
The surveillance requirements for. demonstrating the OPERABILITY of the diesel generators are based on the recommendations in Revision 3 of Regulatory Guide 1.9, " Selection, Design, Qualification,. and Testing of Emergency Diesel Generator Units used as Class IE Onsite Electric Power Systems at Nuclear Power Plants," with the exceptions noted in Appendix A to the UFSAR, and in Revision 1 of Regulatory Guide 1.137, " Fuel-011 Systems for Standby Diesel Generators."
The station chose its largest emergency load to be the SX pump. The maximum BHP of the SX pump is 1247 per UFSAR Table 8.3-1.
A BHP of 1247 corresponds to a load of 1034 kW.

j 3/4.8.1. 3/4.8.2 and 3/4.8.3 A.C. SOURCES. D.C. SOURCES. and ONSITE POWER DISTRIBUTION The OPERABILITY of the A.C. and D.C power sources and associated distribution systems during operation ensures that sufficient power will be i
available to supply the safety-related equipment required for: (1) the safe j
shutdown of the facility, and (2) the mitigation and control of accident condi-tions within the facility. The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements i
i of General Design Criterion 17 of Appendix A to 10 CFR Part 50.
I 1
i The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facihty operation a
commensurate with the level of degradation. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the safety i
j analyses and are based upon maintaining at least one redundant set of onsite 1
A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss-of-offsite power and single failure of the other onsite A.C. source. The A.C. and D.C. source allowable out-of-service times are based on Regulatory Guide 1.93, " Availability of Electrical Power Sources," December 1974. When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components and devices, that depend on j
the remaining OPERABLE diesel generator as a source of emergency power, are i
also OPERABLE, and that the diesel-driven auxiliary feedwater pump is OPERABLE.
This requirement is intended to provide assurance that a loss-of-offsite power event will not result in a complete loss of safety function of critical systems during the Mod one of the diesel generators is inoperable. The term verify j
as used in n.is context means to administrative 1y check by examining logs or other information to determine if certain components are out-of-service for 4
maintenance or other reasons.
It does not mean to perform the Surveillance Requirements needed to demonstrate the OPERABILITY of the component.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and 1
associated distribution systems during shutdown and refueling ensures that:
l (1) the facility can be maintained in the shutdown or refueling condition for j
extended time periods, and (2) sufficient instrumentation and control j
capability is available for monitoring and maintaining the unit status.
l The surveillance requirements for demonstrating the OPERABILITY of the l
diesel generators are based on the recommendations in Revision 3 of Regulatory Guide 1.9, " Selection, Design, Qualification, and Testing of Emergency Diesel Generator Units used as Class IE Onsite Electric Power Systems at Nuclear Power Plants," with the exceptions noted in Appendix A to the UFSAR, and in Revision I of Regulatory Guide 1.137, " Fuel-Oil Systems for Standby Diesel Generators."
The station chose its largest emergency load to be the SX pump. The maximum BHP of the SX pump is 1247 per UFSAR Table 8.3-1.
A BHP of 1247 l
corresponds to a load of 1034 kW.
