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 j

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 I

power sources provide restriction upon continued facility operation commensurate with the level of degradation.

ACTION statements have been included in the specification to cover all situations where either one AC source or a combination of two AC sources are inoperable.

ACTION statements and f are intended to be followed to' completion once entered and should c, e, not bc exited until both AC sources are restored.

The OPERABILITY of the power sources are consistant with the-initial condition assumptions of the accident analyses and are based upon maintaining at least Division I or II of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident.with an assumed loss of of fsite power and single failure of one of the two onsite A.C. sources. Division 'III supplies the high pressure core spray (HPCS) system only.

The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during ihutdown 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 tbe unit status.

The surveillance requirements for dem'onstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power Supplies," March 10, 1971, with the exception noted in Appendix B to the FSAR, and Regulatory Guide 1.100, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1, August 1977.

The diesel generators are equipped with a pre-lubrication system which maintains a continuous flow of oil to the diesel engine moving parts while the engine is shutdown. The purpose of this system is to increase long term diesel generator reliability by reducing the stress and wear caused by frequent dry starting of the diesel generator. The diesel generator pre-lube may be accomplished either through, normal operation of the installed pre-lubrication system, or by manual pre-lubrication of the diesel generator in accordance with manufacturers instructions.

Performance of an idle start j

of the diesel generator is not considered to be a means of pre-lubrication.

ELECTRICAL POWER SYSTEMS BASES A.C. SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS (Continued)

Analysis has shown that testing, which includes a semi-annual f ast start of the diesel generators, is sufficient to demonstrate the capability of the On-Site A.C. power systems to mitigate the consequences of the design basis event for the plant (i.e., large LOCA coincident with a loss-of-offsite-power).

All other engine starts, for the purpose of meeting the diesel generator surveillance requirements, may be preceded by a warm-up period of low speed operation (idle start), and gradual loading procedures, as recommended by the manufacturer, so that the mechanical stress and wear on the diesel generators is minimized.

The load band of 2400 kw to 2600 kw is provided only to avoid routine overloading of the diesel generators.

Momentary transients, outside the load band, due to changing bus loads do not invalidate the surveillance tests.

The surveillance requirements for demonstrating the OPERABILITY of,the unit batteries are in accordance with the recommendations of Regulatory Guide 1.129, " Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February 1978, and IEEE Std. 450-1980, "IEEE Recommended _ Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Station and Substations."

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values and the performance oL battery service and discharge tests ensure 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 4.9.2.3.2-1 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 0.015 below the manuf acturer'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 2.13 volts and not more than 0.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the manuf acturer's ful3 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 4.8.2.3.2-1 is permitted for_up to 7 days.

During this 7 day periodt (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 0.020 below the manufacturer's LASALLE-UNIT 1 B 3/4 8-2 PROPOSED AMENDMENT

ELECTRICAL POWER SYSTEMS BASES A.C.

SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS (Continued) recommended full charge specific gravity, ensures that the decrease in rating I

ELECTRICAL POWER SYSTEMS BASES A.C.

SOURCES AND ONSITE POWER DISTRIBUTION SYSTEMS (Continued)

Analysis has shown that testing, which includes a semi-annual fast start of the diesel generators, is sufficient to demonstrate the capability of the On-Site A.C. power systems to mitigate the consequences of the design basis event for the plant (i.e., large LOCA coincident with a loss-of-offsite-power).

All other engine starts, for the purpose of meeting the diesel generator surveillance requirements, may be preceded by a warm-up period of low speed operation (idle start), and gradual loading procedures, as recommended by the manufacturer, so that the mechanical stress and wear on the diesel generators is minimized. The load band of 2400 kw to 2600 kw is provided only to avoid routine overloading of the diesel generators.

Momentary transients, outside the load band, das to changing bus loads do not invalidate the surveillance tests.

The surveillance requirements for demonstrating-the OPERABILITY of the unit batteries are in accordance with the recommendations of Regulatory Guide 1.129, " Maintenance Testing and Replacement of Large Lead Storage Batteries for Nuclear Power Plants," February 1978, and IEEE Std. 450-1980, "IEEE Recommended Practice for Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating Station and Substations."

Verifying average electrolyte temperature above the minimum for which the battery was sized, total battery terminal voltage on float charge, connection resistance values and the performance of battery service and discharge tests ensure the ef fectiveness of the charging-system, the ability to handle high discharge rates and compares the battery capacity at that time with the rated capacity.

Table 4.8.2.3.2-1 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 0.015 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 nravity, greater than 2.13 volts and not more than 0.020 below the manufacturer's full charge specific gravity with an average specific gravity of all the connected cells not more than 0.010 below the manufacturer's 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 4.8.2.3.2-1 is permitted for up to 7 days.

During this 7 day periods (1) the allowable values for electrolyte level ensures no physical damage to the plates with a. adequate electron transfer capability; (2) the allowable value for the avet sge specific gravity of all the cells, not more than 0.020 below the manufacturer's LASALLE-UNIT 2 B 3/4 8-2 PROPOSEn AMENDMENT

ELECTRICAL POWER SYSTEMS BASES A.c. SOUFCES AND ONSITE POWER DISTRIBUTION SYSTEMS (Continued) recommended full charge specific gravity, ensures that the decrease in rating will be less 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 be more than 0.640 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 thaa 2.07 volts, ensures the battery's capability to perform its design function.

3/4.8.3 ELECTRICAL EQUIPMENT 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.

i The surveillance requirements applicable to lower voltage circuit breakers ar.d fuses provides assurance of breaker and fuse reliability by testing at least one representative, sample of each manuf acturers brand of circuit breaker and/or fuse.

Each ma'nuf acturer's molded ~ case and metal case circuit breakers and/or fuses are grouped into representative samples which are then 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 molded case circuit breakers and/or fuses, it is necessary to divide that manuf acturer'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 valves thermal overload protection continuously or during accident conditions by integral bypass devices ensures that the thermal overload protection will not prevent safety related valves from performing their function. The Surveillance Requirements for demonstrating the bypassing of the thermal overload protection continuously l

and during accident conditions are in accordance with Regulatory Guide 1.106

" Thermal Overload Protection for Electric Motors on Motor Operated Valves",

Revision 1, March 1977.
