SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C pc,wer 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 shutdown of the facility, and 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 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 OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident
]
analyses and are based upon maintaining at least two independent sets 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 one onsite A.C. source.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systtas 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 availablir or monitoring and maintaining the unit status.
The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are based upon. the recommendations of Regulatory Guide 1.9,
" Selection of Diesel Generator Set Capacity for Standby Power Supplies,"
March 10, 1971, and Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977. Regulatory Guide 1.108 criteria for determining and reporting valid tests and failures, and accelerated diesel generator testing, have been superseded by implementation of the Maintenance Rule for the diesel generators per 10CFR50.65.
In adda'. ion to the Surveillance Requirements of 4.8.1.1.2, diesel preventative maintenance is performed in accordance with procedures based on manufacturer's recommendations with consideration given to operating experience.
The minimum voltage and frequency stated in the Surveillance Requirements (SR) are those necessary to ensure the Emergency Diesel Generator (EDG) can accept Design Basis Accident (DBA) loading while maintaining acceptable voltage and frequency levels. Stable operation at the nominal voltage and frequency values is also essential'in esteb11shing EDG OPERABILITY, but a time constraint is not imposed. The lack of a time constraint is based on the fact that a typical EDG will experience a period of voltage and frequency oscillations prior to reaching steady state operation if these oscillations l
are not dampened out by load application.
In lieu of a time constraint in the SR, controls will be provided to monitor and trend the actual time to reach
- stable operation within the band as a means of ensuring there is no voltage regulator or governor degradation that could cause an EDG to become inoperable.

' Standby condition" for the purpose of defining the condition of the engine immediately prior to starting for surveillance requirements requires that the lube oil temperature be between 100 *F and 170 'F.
The minimum lube oil temperature for an OPERABLE diesel. is 100 "F.
The thirteen second time requirement for the Emergency Diesel Generator to reach rated voltage and frequency was originally based on a Westinghouse j
asst.mption of fifteen seconds that included the delay time between the
{
occurrence of the incident and the application of electrical power to the j
first sequenced safeguards pump (BURL-3011, dated November 13, 1974) and included an instrument response time of two seconds (BURI.-1531, dated July 27, 1970). The times specified in UFSAR Section 15.4 bound the thirteen seconda specified in the TS.
I The narrower band for frequency specified for testing performed in steady
' state isochronous operation will ensure the EDG will not be run in an overloaded condition (steady state) during accident conditions. Steady state is assumed to be achieved after one minute of operation in the isochronous
]
mode with all required loads sequenced on the bus.
e,
~
The narrower band for steady state voltage is specified for operation when the EDG is not synchronized to the grid to ensure the voltage regulator will protect driven equipment from over-voltages during accident conditions.
Procedural controls will ensure that equipment voltages are maintained within acceptable limits during testing when paralleled to the grid.
1 The wider band for frequency is appropriate for testing done with the governor i
- in the droop mode. Likewise the wider band for voltage is appropriate when paralleled to the grid.
All voltages and frequencies specified in SR 4.8.1.1.2 are representative of i
the analytical values and do not account for postulated instrument inaccuracy.
j Instrument inaccuracies for EDG voltage and frequency are administratively j
controlled.
l Preventive maintenance includes those activities (including pre-test inspections, measurements, adjustments and preparations) performed to maintain an otherwise CPERABLE EDG in an OPERABLE status. Corrective maintenance includes those activities required to correct a condition that would cause the EDG to be inoperable.
S surveillance requirement 4.8.1.2 is modified by a Note. The reason for the Note is to preclude requiring the OPERABLE DG(s) from being paralleled with the offsite power network or otherwise rendered inoperable during performance i
of the surveillance requirement, and to preclude de-energizing a required ESF j
bus or disconnecting a required offsite circuit during performance of j
surveillance requirements. With limited AC sources available, a single event could compromise both the required circuit and the DG.

SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS 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 conditions within the facility. The c.inimum 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 ocurces provide restriction upon continued facility operation commensurate with the level of degradation..The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least two independent sets of onsite A.C. and D.C. power sources and casociated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of one onsite A.C. source.
The OPERABILITY of the minimum specified A.C. and D.C. power sources and casociated distribution systems during shutdot:n 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 Eonitoring and maintaining the unit status.
The Surveillance Requirements for demonstrating the OPERABILITY of the diesel g:nerators are based upon the recommendations of Regulatory Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power Supplies," March 10, 1971, and Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977. Regulatory Guide 1.100 criteria for determining and reporting valid tests and failures, and eccelerated diesel generator testing, have been superseded by implementation of the Maintenance Rule for the diesel generators per 10CFR50.65.
In addition to the Surveillance Requirements of 4.8 1.1.2, diesel preventative maintenance is performed in accordance with procedures based on manufacturer's recommendations with consideration given to operating experience.
The minimum voltage and frequency stated in the Surveillance Requirements (SR) j are those necessary to ensure the Emergency Diesel Generator (EDG) can p.ccept Design
- % sis Accident (DBA) loading while maintaining acceptable voltage and frequency levels. Stable operation at the nominal voltage and frequency values is also l
cssential in' establishing EDG OPERABILITY, but a time constraint is not imposed.
l The lack of a time constraint is based on the fact that a typical EDG will l
cxperience a period of voltage ano frequency oscillations prior to reaching steady state operation if these oscillations are not dampened out by load application.
In lieu of a time constraint in the SR, controls will be provided to monitor and trend the actual time to reach stable operation within the band as a means of ensuring there is no voltage regulator or governor degradation that could cause an EDG to j-become inoperable.

' Standby condition" for the purpose of defining the condition of the engine immediately prior to starting for surveillance requirements requires that the lube cil temperature be between 100 'F and 170 'F.
The minimum lube oil temperature for an OPERABLE diesel is 100 'F.
The thirteen second time requirement for the Emergency Diesel Generator to reach r:ted voltage and frequency was originally based on a Westinghouse assumption of fifteen seconds that included the delay time between the occurrence of the incident and the application of electrical power to the first sequenced safeguards pump (IURL-3011, dated November 13, 1974) and included an instrument response time of two ccconds (BURL-1531, dated July 27, 1970). The times specified in UFSAR Section 15.4 bound the thirteen seconds specified in the TS.
l The narrower band for frequency specified for testing performed in steady state icochronous operation will ensure the EDG will not be run in an overloaded condition (steady state) during accident conditions. Steady state is assumed to be achieved efter one minute of operation in the isochronous mode with all required loads requenced on the bus, i
The narrower band for steady state voltage is specified for operation when the EDG is not synchronized to the grid to ensure the voltage regulator will protect driven equipment from over-voltages during accident conditions. Procedural controls will cnsure that equipment voltages are maintained within acceptable limits during t: sting when paralleled to the grid.
The wider band for frequency is appropriate for testing done with the governor in the droop mode.
Likewise the wider band for voltage is appropriate when paralleled i
to the grid.
All voltages and frequencies specified in SR 4.8.1.1.2 are representative of the analytical values and do not account for postulated instrument inaccuracy.
Instrument inaccuracies for EDG voltage and frequency are administratively centrolled.
Preventive maintenance includes those activi'.ies (including pre-test inspections, measurements, ad-)ustments and preparations) performed to maintain an otherwise
- OPERABLE EDG in an OPERABLE status. Corrective maintenance includes those cctivities required to correct a condition that would cause the EDG to be i
Surveillance requirement 4.8.1.2 is modified by a Note.
The reason for the Note is j
to preclude requiring tho' OPERABLE DG(s) from being paralleled with the offsite power network or otherwise rendered inoperable during performance of the curveillance requirecint, and to preclude de-energizing a required ESF bus or l
disconnecting a required offsite circuit during performance of surveillance requirements. With limited AC sources available, a single event could compromise i
both the required circuit and the DC.
It is the intent that i
