The 125-Volt battery system shall have a minimum of 105 Volts at the battery terminals to be considered operable.
The 250-Volt portion of the 125/250-Volt battery system shall have a minimum of 210 Volts.at the battery terminals to be considered ope r able.
The ESWS has two 100 per cent cooling capacity pumps, each powered from a separate standby power supply.
A third pump equivalent to the two ISW pumps, the Emergency Cooling Water
.pwnp, is located at the Emergency Cooling Tower.
This latter l
pump requires the operability of one of the two ESW booster pumps and two of the three Emergency Cooling Tower fans to function adequately.
In the event 2 pumps are inoperable, the allowable repair period is conservative in view of the 3-month test interval for the system.
4.9 BASES The monthly test of the diesel generator is conducted to check for equipment failures and deterioration.
Testing is conducted up to equilibrium operating conditions to demonstrate proper operation at these conditions. The diesel generator will be manually started, synchronized and connected to the bus and load picked up.
The diesel generator should be loaded to at least 75% of rated load to prevent fouling of the engine.
It is expected that the diesel generator will be run for one to two hours.
Diesel generator experience at other generating stations indicates that the testing frequency is adequate and provides a high reliability of operation should the system be required.
Each diesel generator has one air compressor and two air receivers for starting.
It is expected that the air compressors will run only infrequently.
During the monthly check of the diesel gen-erator, one. receiver in each set of receivers will be drawn down below the point at which the corresponding compressor auto-
.matically starts to check operation and the ability of the compressors to recharge the receivers.
The diesel generator fuel consumption rate at full load is approxi-mately 200 gallons per hour.
Thus, the monthly load test of the diesel generators will test the operation and the ability of the fuel oil transfer pumps to refill the day tank and w the operation of these pumps from the emergency sou ill check rce.
The test of the diesel generator during the refueling outage will be more comprehensive in that it will functionally test the system; i.e., it will check diesel generator starting and closure of diesel generator breaker and sequencing of load on the diesel generator.
The diesel generator will be started by simulation of a loss-of-coolant accident.
In addition, an undervoltage ccndition will be imposed to simulate a loss of off-site power. The timing sequence will be checked to assure that the diesel generators can operate the LPCI pumps at rated speed within 18 seconds, ar.d the core spray pumps at rated speed within twenty-four seconds.
-223-APRIL 1973
PBAPS Unit 2 4.9 BASES (Cont'd.)
Periodic tests between refueling outages verify the ability of the diesel generator to run at full load and the core and containment cooling pumps to deliver full flow.
Periodic testing of the various components, plus a functional test one-a-cycle, is sufficient to maintain adequate reliability.
Although station batteries will deteriorate with time, utility experience indicates there is almost no possibility of precipitous failure.
The type of surveillance described in this specification is that which hss been demonstrated over the years to provide an indication of a cell becoming irregular or unserviceable long before it becomes a failure.
In addition, the checks described also provide adequate indication that the batteries have the specified ampere hour capability.
The station batteries shall be subjected to'a performance test every third refueling outage and a service test during the other refueling outages.
This testing frequency complies with the testing requirements of the Institute of Electrical and Electronics Engineers (IEEE) Standard 450(1975),
"Reccmmended Practico for Maintenance, Testing and Replacement of Large Lead Storage Batteries," and Regulatory Guide 1.129, Revision 1 (February 1978), "Maintenance, Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants."
A performance test determines the ability of the battery to meet a specified discharge rate and duration based on the manufacturer's rating.
A service test proves the capability of the battery to delivei the design requirements of the de systemst i.e.,
supply and maintain in operable status all of the actual emergency loads for the design basis accident.
A performance test is the most severe test because the cycling on the battery at manufacturer's rating shortens the service life of the battery.
A service test is performed at design load instead of manufacturer's ratings.
The diesel fuel oil quality must be checked to ensure proper operation of the diesel generators.
Water content should be minimized because water in the fuel could contributa to excessive damage to the diesel engine.
Amendment No. L1 centralized commitments related to Position C.2 of Regulatory Guide 1.137, Revision 1 (October, 1979) "Fuel Oil Systems for Standby Diesel Generators".
When it is determined that some auxiliary electrical equipment is out-of-service, the increased surveillance required in Section 4.5.F is deemed adequate to provide assurancs that the remaining equipment will be operable.
The test interval for.the Emergency Service Water System, plus the ESW booster pumps, Emergency Cooling Tower fans, and pump room fans associated with the ESW pumps is deemed adequate to provide assurance that the equipacnt will be j
operable based on good engineering judgment and system redundancy, plus the additional testing accomplished when the diesel generators are tested.
Pump flow tests during normal operation will be performed by measuring the shut-off head.
Amendment No.

The 125-Volt battery system shall have a minimum of 105 Volts the battery terminals to be considered operable.
The ;50-at Volt portion of the 125/250-Volt battery system shall have a minimum of 210 Volts.at the battery terminals to be considerad operable.
The ESWS has two 100 per cent cooling capacity pumps, each powered from a separate standby power supply.
A third pump equivalent to the two ESW pumps, the Emergency Cooling Water pump, is located at the Emergency Cooling Tower. This latter j
pump requires the operability of one of the two ESW booster pumps and two of the three Emergency Cooling Tower fans to function adequately.
In the event 7 oumps are inoperable, the allowable repair period is conse rvative in view of the 3-month test interval for the system.
4.9 BASES The monthly test of the diesel generator is conducted to check for equipment failures and deterioration.
Testing is conducted up to equilibrium operating conditions to demonstrate proper operation at these conditions. The diesel generator will be manually started, synchronized and connected to the bus and load picked up.
The diesel generator should be loaded to at least 75% of rated load to prevent fouling of the engine.
It is expected that the diesel generator will be run for one to two hcurs.
Diesel generator experience at other generating stations indicates that the testing frequency is adequate and peovides a high reliability of operation should the system be required.
Each diesel generator has one air compressor and two air receivers for starting.
It is expected that the air compressors will run only infrequently.
During the monthly check of the diesel gen-erator, one receiver in each set of receivers will be drawn down below the point at which the corresponding compressor auto-natically starts to check operation and the ability of the compressors to recharge the receivers.
i The diesel generator fuel consumption rate at full load is approxi-mately 200 gallons per hour.
Thus, the monthly load test of the diesel generators will test the operation and the ability of the fuel oil transfer pumps to r& fill the day tank and will the operation of these pumps from the emergency source. check The tesc of the diesel generator during the refueling outage will be more comprehensive ir. that it will functionally test the systems i.e., it will check diesel generator starting and closure 1

a loss-of-coolant accident.
In addition, an undervoltage condition will be imposed to simulate a' loss of off-site power.
The timing sequence will be checked to assure that the diesel gdnerators can operate the LPCI pumps at rated speed within 18 seconds, and the core spray pumps at rated speed within twenty-four seconds.

4.9 BASES (Cont'd.)
Periodic tests between refueling outages verify the ability of the. diesel genecator to run at full load and the core and containment cooling pumps to deliver full flow.
Periodic testing of the various components, plus a functional test one-a-cycle, is sufficient to maintain adequate reliability.
Although station betteries will deteriorate with time, utility experience indicates there is almost no possibility of precipitous failure.
The type of surveillance described in this specification is that which has been demonstrated i
over the years to provide an indication of a cell becoming irregular or unserviceable long before it becomes a failure.
In addition, the checks described also provide adequate indication that the batteries have the specified ampere hour capability.
The station batteries shall be subjected to a performance test every third refueling outage and a service test during the other refueling outages.
This testing frequency complies with the testing requirements of the Institute of Electrical and E16ctronics Engineers (IEEE) Standard 450 (1975),
"Reccmmended Practico for Maintenance, Testing and Replacement of Large Lead Storage Batteries," and Regulatory Guide 1.129, Revision 1 (Februarf 1978), "Maintenance, Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants."
A performance test determines the ability of the battery to meet a specified discharge rate and duration based on the manufacturer's rating.
A service test proves the capability of the battery to deliver the design requirements of the de systems; i.e.,
supply and maintain in operable status all of the actual emergency loads for the design basis accident.
A performance test is the most severe test because the cycling on the battery at manufacturer's rating shortens the service life of the battery.
A service test is performed at design load instead of manufacturer's ratings.
The diesel fuel oil quality must be checked to ensurc proper j
operation of the diesel gene-ators.
Water content should be minimized because water in tne fuel could contribute to excessive damage to the diesel engine.
Amendment No. 1 centralized commitments related to Position C.2 of Regulatory Guide 1.137, Revision 1 (October, 1979) "Fuel Oil Systems for Standby Diesel Generators".
When it is determined that some auxiliary electrical equipment is out-of-service, the increased surveillance 1
required in Section 4.5.F is deemed adequate to provide assurance that the remaining equipment will be operable.
The test interval for the Emergency Service Water System, plus the ESW booster pumps, Emergency Cooling Tower fans, and pump room fans associated with the ESW pumps is deemed adequate to provide assurance that the equipment will be operable based on good engineering judgment and system redundancy, plus the additional testing accomplished when the diesel generators are tested.
Pump flow tests during normal operation will be performed by measuring the shut-off head.
