3/4. 8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1 3/4.8.2 and 3/4.8.3 A.C. SOURCES O.C. SOURCES and ONSITE POWER OIS U ON YS S The OPERABILITY of the A.C. and O.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 D. C. power sources and distribution systems satisfy the requirements of General Design Crfterfa 17 of Appendix "A" to 10 CFR 50.
The ACTION requirements specified for the levels of degradation of the power sources provide restrictfon upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are con-sistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least three of the onsite A.C. and the corre-sponding D.C. power sources and assocfated distribution systems OPERABLE during accident conditions coincident with an as e 'loss of offsite power and single failure of one other onsite A. C. source. +~ss~A 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. This requfrement 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 admfnfstratfvely check by examining logs or other fnformation to determine if certain components are out-of-service for maintenance or other r'easons. It does not mean'o 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 facfltty can be maintained fn 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 in accordance wfth the recomaendatfons of Regulatory Guide 1.9, "Selection of Diesel Generator Set Capacity for Standby Power Supplies", March 10, 1971, Regulatory Guide 1. 108, "Periodic Testing of Diesel Generator Units Used as Onsfte Electric Power Systems at Nuclear Power Plants",
Revision 1, August 1977 and Regulatory Guide 1.137 "Fuel-Oil Systems for Standby Diesel Generators", Revision 1, October 1979.

The. surveillance requirements for demonstrating the OPERABILITY of the unit batteries are fn accordance with* the recommendations of Regulatory Guide I. 129, "Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants", February 1978, and IEEE Std 450-1980, "IEEE Recom-mended Practica for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Stations and Substations."
Verffyfng average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage onfloat charge, connection resistance values and the performance of battery service and. discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates and compares tha battery capacity at that time with the rated capacity.
Table 4.8.2.1-1 specifies the normal limits for each designated pi lot cell and each connected cell for electrolyte level, float voltage and specific gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2. 13 volts and .015 below the manufactUFer's full charge specfffc gravity or a battery charger current that had stabilized at a Iow value, fs characteristfc of a charged .cell. with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.13 volts and not mora than .020 below the manufacturer' full charge specific gravity with an average specific gravity of all the connected .cells not more than .010 below the manufacturer ' ful I charge specific gravity, ensures the OPERABILITY and capability of the battery.
Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8.2. 1-1 is permitted for up to 7 days. Ouring this 7 day period: (1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, not more than .020 below tha manufacturer's recommended full charge specific gravity, ensures that the decrease in rating will be less than the safety margfn provided in sizing; (3) the allowable value for an individual cell's specific gravity ensu'res that an individual cell's specific gravity will not be more than .040 below the manufacturer's full charge specific gravity and that the overall capability of the battery will be maintained within an acceptable, limit; and (4) the allowable value for an individual cell's float voltage, greater than 2.07 volts, ensures the battery' capability to perform fts design function.

ELECTRICAL POWER SYSTEMS BASES 3/4.8.4 ELECTRICAL E UIPMENT PROTECTIVE DEVICES Primary containment electrical penetrations and penetration conductors are protected by either de-energizing circuits not required during reactor operation or demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers by periodic surveillance.
The surveillance requirements applicable to lower voltage circuit breakers and fuses provides assurance of breaker and fuse reliability by testing at least one representative sample of each manufacturers brand of circuit breaker and/or fuse. Each manufacturer's molded case and metal case circuit breakers and/or fuses are grouped into representative samples which are than tested on a rotating basis to ensure that all breakers and/or fuses are tested. If a wide variety exists within any manufacturer's brand of circuit breakers and/or fuses, it is necessary to divide that manufacturer's breakers and/or fuses into groups and treat each group as a separate type of breaker or fuses for surveillance purposes.
The bypassing of the motor operated valve thermal overload protection continuously by integral bypass devices ensures that the thermal overload protection will not prevent .safety related valves from performing their func-tion. The surveillance requirements for demonstrating the bypassing of the thermal overload protection continuously are in accordance with Regulatory Guide 1. 106 "Thermal Overload Protection for Electric Motors on Motor Operated Valves", Revision 1, March 1977.

SOURCES and ONSITE POWER 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 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 facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are con-sistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least three of the onsite A.C. and the corre-sponding D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an a umed loss of offsite power and single failure of one other onsite A.C. source +xusae'h 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. 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 administratively check by examining logs or other information to determine if certain components are out-of-service for maintenancezr 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 in accordance with the recommendations of Regulatory Guide 1.9, 45election of Diesel Generator Set Capacity for Standby Power Supplies", March 10, 1971, Regulatory Guide 1. 108, Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants",

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage onfloat charge, connection resistance values and the performance. of battery service and discharge tests ensures the effectiveness of the charging system, the ability to handle high discharge rates and. compares the battery capacity at that time with the rated capacity.
Table 4.8.2.1-1 specifies the normal limits for each designated pilot cell and each connected cell for electrolyte level, float voltage and specific gravity. The limits for the designated pilot cells float voltage and specific gravity, greater than 2.13 volts and .OL5 below the manufacturer's full charge specific gravity or a battery charger current that had stabilized at a low value, is characteristic of a charged cell with adequate capacity. The normal limits for each connected cell for float voltage and specific gravity, greater than 2.H volts and not more than .020 below the manufacturer's full charge specific gravity with an average specific ' gravity of all the connected cells not more than . 010 below the manufacturer full charge specific gravity, ensures the OPERABILITY and capability of the battery.
Operation with a battery cell's parameter outside the normal limit but within the allowable value specified in Table 4.8.2.1-1 is permitted for up to 7 days. During this 7 day, period: (1) the allowable values for electrolyte level ensures no physical damage to the plates with an adequate electron transfer capability; (2) the allowable value for the average specific gravity of all the cells, nat more than .020 below the manufacturer's recoaxaended full charge specific gravity, ensures that the decrease in rating will be Cess than the safety margin provided in sizing; (3) the allowable value for an individual cell's specific gravity ensures that an individual cell's specific gravity will not ba more than .040 below the manufacturer's full charge specific gravity and that thi overall capability of the battery will be maintained within an acceptable limit; and (4) the allowable value for an individual cell's float voltage, greater than 2.07 volts, ensures the battery's capability to perform its design function.

The purpose of these tests is to demonstrate that the associated test signals cause a diesel start. The first part of this surveillance 14.8.1.1.3.4.6 combines these three tests into one on the basis that once the diesel has started via one of the test signals, it is only necessary to verify that the relays associated with the other test signals are working. The second part of this surveillance provides the option of performing the three tests utilizing a load. Existing surveillance 4.8.1.1.2.d.4 performs a diesel generator auto start on a simulated loss of offsite power. This requires a dead bus which is only available during outages. Technically, this surveillance checks bus undervoltage sensing devices and diesel generator capability. The bus undervoltage relays are part of the existing Plant and have not been affected by installation of a fifth diesel generator. Diesel generator E's ability to auto start and load is independent of where the load originates therefore a load bank is acceptable. Existing surveillance 4.8.1.1.2.d.6 performs a diesel generator auto start on a simulated LOCA/LOOP signal followed by diesel generator loading according to design sequencing. This surveillance is intended to check the automatic load sequence timers and diesel generator capability. -The sequence timers are not part of the bus or diesel logic but are part of the individual load control schemes.
