3/4 BASES 3/4.8 ELECTRICALPOWER SYSTEMS The OPERABILITYof 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 facilityand 2) the mitigation and control of accident conditions 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 Criteria 17 of Appendix A" to 10 CFR 50.
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facilityoperation commensurate with the level ofdegradation.
The OPERABILITYofthe power sources are consistent with the initialcondition assumptions of the accident analyses and are based upon maintaining at least one of each of the 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 OPERABILITYof the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that 1) the facilitycan 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 facility status.
The AB and CD station battery s'ystems provide a reliable source of continuous power for supply and control of plant loads such as switchgear and annunciator control circuits, static inveriers, valve control centers, emergency lighting and motor control centers.
The design duty cycles of these batteries are composite load profiles resulting from the combination of the three hour Loss Of Coolant Accident/Loss Of Offsite Power battery load profiles and the four hour Station Blackout battery load profiles.
The train N station bat tery system provides an independent 250 volt DC power supply for power and control of the turbine driven auxiliary feedwater pump train.
The limiting conditions of operation for the train N battery are consistent with the requirements of the auxiliary feedwater system.
The surveillance requirements for the train N battery system are consistent with the requirements of the AB and CD station batteries.
The train N battery loads are derived from equipment in the turbine driven auxiliary feedwater pump train and battery sizing is consistent with the functional requirements ofthese components.
Simulated loads for battery tests are loads equivalent to measured actual loads.

3/4 BASES 3/4.8 ELECTRICALPOWER SYSTEMS Removal of accumulated water as required by 4.8.1.1.2.b.2 is performed by drawing the contents offthe bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test.
An acceptable result for the water and sediment content is a measured value less than 0.05 percent volume.
The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious attempt willbe made to meet the 31-day limiton the offsite tests; however, iffor some reason this limitis not met (e.g., ifthe sample is lost or broken or ifthe results are not received in 31 days), the diesel generators should not be considered inoperable. Ifthe sample is lost, broken, or fails the offsite tests and the new oil has already been put into the storage tank, the offsite tests willbe perforined on a sample taken from the storage tank. Ifthe results on the subsequent storage tank sample are not withinspecified limits, the diesel generators should be considered OPERABLE and the outwf-spec properties should be returned to within specification as soon as possible.
If the monthly storage tank sample taken in accordance with Specification 4.8.1.1.2.d fails the particuIate contamination test, the diesel generators should be considered OPERABLE and the contamination level should be restored to below 10 mg/liter as soon as possible.
The precision leak-detection test described in Surveillance Requirement 4.8.1.1.2.f.2 should be performed as described in NFPA (National Fire Protection Association) -329.
As NFPA-329 is revised, the precision leak-detection test may be modified to incorporate changes to the test as described in the revisions to NFPA-329, The minimum required diesel fuel oil volume is 43,240 gallons.
This volume is consistent with operation of one diesel generator continuously for 7 days at rated load, as recommended in Regulatory Guide 1.137, entitled "Fuel Oil Systein for Standby Diesel Generators."
The Technical Specifications require a minimum of 46,000 gallons of fuel. The 46,000 gallons is an indicated volume. This amount includes margin for characteristics such as location of the tank discharge pipes and slope of the tanks.

3/4 BASES 3/4.8 ELECTRICALPOWER SYSTEMS The OPERABILITYof the A.C. and D.C power sources and associated distribution systems during operatioa ensures th'at sufficient power will be available to supply the safety related equipment required for 1) the safe shutdown of the facilityand 2) the mitigation and control of accident conditions 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 Criteria 17 of Appendix "A" to 10 CFR 50.
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facilityoperation commensurate with the level ofdegradation.
The OPERABILITYofthe power sources are consistent with the initialcondition assumptions of the accident analyses and are based upon maintaining at least one of each of the onsite A.C. aad D.C. power sources and associated distribution systems OPERABLE duriag accident conditions coincident with an assumed loss of offsite power and single failure of the other oasite A.C.
The OPERABILITYof the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that 1) the facilitycan be maintained in the shutdowa or refueling condition for extended time periods and 2) sufficient instrumentation and coauol capability is available for monitoring and maintaining the facilitystatus.
The AB and CD station battery systems provide a reliable source of continuous power for supply and control of plant loads such as switchgear and annunciator control circuits, static inverters, valve control centers, emergency lighting and motor control centers.
The desiga duty cycles of these batteries are composite load profiles resulting
&om the combination of the three hour Loss Of Coolant Accident/Loss Of Offsite Power battery load p'rofiles and the four liour Station Blackout battery load profiles.
The train N station battery system provides aa indepeadent 250 volt DC power supply forpower and control of the turbine driven auxiliary feedwater pump train.
The limitiag conditions of operatioa for the train N battery are consistent with the requirements of the auxiliary feedwater system.
The surveillance requirements for the train N battery system are consistent with the requirements of the AB and CD station batteries.
The train N battery loads are derived from equipmeat in the turbine driven auxiliary feedwater pump train and battery sizing is consistent with the functional requirements of these components.
Simulated loads for battery tests are loads equivalent to measured actual loads.

3/4 BASES 3/4,8 ELECTRICALPOWER SYSTEMS Removal of accumttiated water as required by 4.8.1.1.2.b.2 is performed by drawing the contents offthe bottom of the tank until acceptable results are obtained for either a tape test or a water and sediment test.
An acceptable result for the water and sediment content is a measured value less than 0.05 percent volume.
The sample specified in 4.8.1.1.2.c.4 is sent offsite for testing. A serious attempt willbe made to meet the 31'imit on the offsite tests; however, iffor some reason this limitis not met (e.g., ifthe sample is lost or broken or ifthe results are not received in 31 days), the diesel generators should not be considered inoperable. Ifthe sample is lost, broken, or fails the offsite tests and the new oil has already been put into the storage tank, the offsite tests willbe performed on a sample taken from the storage tank. Ifthe results on the subsequent storage tank sample are not withinspecified limits, the diesel generators should be considered OPERABLE and the outwf-spec properties should be returned to withinspecification as soon as possible.
If the monthly storage tank sample taken in accordance with Specification 4.8.1.1.2.d fails the particulate contamination test, the diesel generators should be considered OPERABLE and the contamination level should be restored to below 10 mg/liter as soon as possible.
The precision leak-detection test described in Surveillance Requirement 4.8.1.1.2.f.2 should be performed as described in NFPA (National Fire Protection Association) -329.
As NFPA-329 is revised, the precision leak-detection test may be modified to incorporate changes to the test as described in the revisions to NFPA-329.
The minimum required diesel fuel oil volume is 43,240 gallons.
This volume is consistent with operation of one diesel generator continuously for 7 days at rated load, as recommended in Regulatory Guide 1.137, entitled "Fuel Oil Systein for Standby Diesel Generators.
The Technical'Specifications require a minimum of 46,000 gallons of fuel. The 46,000 gallons is an indicated volume. This amount includes margin for characteristics such as location of the tank discharge pipes and slope of the tanks.
