3/4.8 ELECTRICAL POWER SYSTEMS BASES 224.3 1 and 3/4.8.2. A.C. SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. pow-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 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 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 is consistent with the initial condition assumptions of the safety analyses and is based upon maintaining at least one redundant set of onsite A.C. and D.C. power sources and associated distribution s/ stems OPERABLE during accident :onditions coincident with.an assumed loss of of fsite power and single failure of the othe* onsite A.C.

source.

The OPERABILITY of the minimum specified A.C. and 0.C. power sources and associated distribution systems during shutdown and refueling ensures that 1) the facility can be maintainea 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.

In order to comply with 10 CFR 50.63, " Loss of Ali Alternating Current Power," and the guidance in Regulatory Guide 1.155, " Station Blackout," the minimum reliability for emergency diesel generators has been targeted at 0.95.

.Each emergency diesel generator is tested monthly for the purpose of monitoring 3 potential degradation in reliability.

All data from planned and unplanned demands are used in monitoring which is based on the last 100 demands of all emergency diesel generators for Unit 1 as specified in 10 CFR 50.63(a)(3). Criteria for determining the number of failures and valid demands shall be in accordance with NUMARC 87-00, Appendix D, Revision 1, where the number of demands and failures are determined on a per emergency diesel generator basis and combined for all emergency diesel generators for Unit I to evaluate reliability and determine corrective action.

The criteria are based upon counting only those failures that have an impact on the capability of the emergency diesel generator to respond to a station blackout.

The Surveillance Requirements for demonstrating the OPERABILITY of the Station batteries are based on the recommendations of IEEE Standard 450-1980,

"!EEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations."

i 3/4.8 ELECTRICAL 90BER SYSTEMS BASES 3/4.8.1 and 3/4.8.2.A.C. 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 minimum specified independent and redundant A.C. and 0.C. power sources and distribution systems satisfy the requirements of General Design Criterion 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 facility operation commensurate with the level of degradation.

The OPERABILITY of the power sources is consistent with the initial condition assumptions of the safety analyses and is based upon maintaining at least one redundant set of onsite A.C. and 0.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 OPERABILITY of the minimum specified A.C. and 0.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 In order to comply with 10 CFR 50.63, " Loss of All Alternating Current Power," and the guidance in Regulatory Guide 1.155, " Station Blackout," the minimum reliability for emergency diesel generators has been targeted at 0.95.

Each emergency diesel generator is tested monthly for the purpose of monitoring potential degradation in reliability.

All data from planned and unplanned demands are used in monitoring which is based on the last 100 demands of all emergency diesel generators for Unit 2 as specified in 10 CFR 50.63(a)(3).

Criteria fa-determining the number of failures and valid demands shall be in accordance witi.

NUMARC 87-00, Appendix 0, Revision 1, where the number of demands and failures are determined on a per emergency diesel generator basis and combined for all emergency diesel generators for Unit 2 to evaluate reliability and determine corrective action.

The criteria are based upon counting only thbse failures that have an impact on the capability of the emergency diesel generator to respond to a station blackout.

The Surveillance Requirements for demonstrating the OPERABILITY of the Station batteries are based on the recommendations of IEEE Standard 450-1980, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations."

3/4.8.3 ELECTRICAL E0UIPMENT PROTECTION DEVICES Containment electrical penetrations and penetration conductors are protected by either deenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of overcurrent protection circuit breakers during periodic surveillance.
