3/4.0 APPLICABILITY BASES The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4.

3.0.1 This specification states the applicability of each specification in terms of defined OPERATIONAL CONDITION or other specified applicability condition and is provided-to delineate specifically when each specification is applicable.

3.0.2 This specification defines those conditions necessary to constitute-compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.

3.0.3 This specification delineates the ACTION to be taken for' circumstances not directly provided for'in the ACTION statements and whose occurrence would violate the intent of specification.1 For example, Specification 3.5.1 calls for the HPCI to be OPERABLE and specifies explicit requirements if it becomes inoperable. Under the requirements of Specification 3.0.3, if the required additional systems are not OPERABLE, within one hour measures must be initiated to place the unit in at least STARTUP within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , and in COLD SHUTDOWN within the subsequent 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . As a further example, Specification 3.1.3.1 requires that all control rods shall'be OPERABLE and provides explicit ACTION requirements (3.1.3.1.a) if,one control rod is inoperable due to being immovable, as a result-of excessive friction or mechanical incerference, or known to"be untrippable..Under the requirements of Specification 3.0.3, if more than one control rod is inoperable per 3.1.3.1.a, within one hour measures must be initiated to place the unit in at least STARTUP within the t

next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and at laast if0T SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months .

t 3.0.4 This specification provides that entry into an OPERABLE CONDITION must be made with (a) the full complement of required systems, equipment or components OPERABLE and (b) all other parameters as specified in the Limiting

'f*)'

Conditions 'for Operation beitig met without regard for allowable deviations and out-of-service provisions contained in the ACTION statements.

The intent of this provision is to ensure that facility operation is not ir,itiated with either required equipment or systems inoperable or other limits being exceeded.

Exceptions to this provision have been provided for a limited number of specifications when startup with inoperable equipment would not affect plant i

safety. These exceptions are stated in the ACTION statements of the appropriate specifi' cations.

'3/4.8 ELECTRICAL POWER SYSTEMS

-BASES 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 i

criteria 17 of Appendix "A" to 10 CFR 50.

F The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate n

with the level of degradation. The OPERABILITY of the power sources is consistent with the initial condition assumptions of the accident analyses and is based upon maintaining at least one of each of the onsite A.C. and the corresponding D.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. or D.C. source.

i This specification also delineates what additional conditions must be i

satisfied to permit operation to continue when a power source is not l'

OPERABLE. When a diesel generator or off-site power source to an emergency bus is inopereble, there is an additional ACTION requirement to verify that redundant safety systems, subsystems, trains, components, and devices, that depend on the remaining OPERABLE power sources are also OPERABLE. This requirement is intended tc provide assurance that a loss of offsite power event will not result in a complete loss of the safety functions of critical systems. It specifically prohibits operation when one diesel generator or one f

of the required off-site power sources to an emergency bus is inoperable and a redundant system, subsystem., train, component, or device powered from another diesel generator is inoperable for another reason.

The provisions of this specification permit the ACTION statements associated with individual systems, sub. systems, trains, components, or devices to be consistent with the ACTION statements of the associated electrical power source. It allows operation to be governed by the time limits of the ACTION statement associated with the Limiting Condition for Operation for the emergency power source, not the individual ACTION statements for each system, i

subsystem, train, component, or device that is determined to be inoperable l

solely because of the inoperability of its emergency power source.

For example, Specification 3.8.1.1 requires, in part, that all four emergency l

diesel generators be OPERABLE. The ACTION statement provides for a 3 day out-of-service time when one emergency diesel generator is not OPERABLE.

If the definition of OPERABLE were applied without consideration of Specification 3.8.1.1 ACTION b.2, all systems, subsystems, trains, components, j

and devices supplied by the inoperable emergency power source would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the Limiting Condition for Operation. However, the provisions of i

Specification 3.8.1.1 ACTION b.2 permits the time limits for continued BRUNSWICK - UNIT 1 B 3/4 8-1 Amendment No.

(BSEP-1-93)

BASES (Continued) operation to be consistant with the ACTION statement for the inoperable emergency diesel generator instead, provided the other specified conditions are satisfied. If they are not satisfied, shutdown is required in accordance with this specification.

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) sutficient instrumentation and control capability is available for monitoring and maintaining the unit status.

The surveillance requirements for demonstrating the OPERABILITY of the unit batteries are in accordance with the recommendations of the battery manufacturer and sound maintenance practices.

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 capacity 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 4.8.2.3.2-1 specifies the normal'1imits 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 or equal to 2.13 volts and specific gravity not more than 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 gravity, greater than or equal to 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 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 0.020 below the manufacturer's recommended full charge specific gravity ensures that the decrease in rating will be less than the safety cargin provided in sizing; (3) the allowable value for an indivdual cell's specific gravity ensures that an individual cell's specific gravity will not be more than 0.020 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 or equal to 2.07 volts, ensures the battery's capability to perform its design function.

3/4.0 APPLICABILITY BASES b

The specifications of this section provide the general requirements applicable j

to each of the Limiting conditions for Operation and Surveillance Requirements i

within section 3/4.

[

3.0.1 This specification states the applicability of each specification in terms of defined OPERATIONAL CONDITION or other specified applicability condition and is provided to delineate specifically when each specification is applicable.

3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting condition for Operation and associated ACTION requirement.

3.0.3 This specification delineates the ACTION to be taken for circumstances i

not directly provided for in the ACTION statements and whose occurrence would violate the intent of specification. For example, Specification 3.5.1 calls j

for the HPCI to be OPERABLE and specifies explicit requirements if it becomes 1

Inoperable. Under the requirements of Specification 3.0.3, if the required i

additional systems are not OPERABLE, within one hour measures must be initiated to place the unit in at least STARTUP within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , in at l

the subsequent 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months . As a further example, Specification 3.1.3.1 requires that all control rods shall be OPERABLE and provides explicit ACTION requirements (3.1.3.1.a) if one control rod is inoperable due to being 4

l Lamovable, as a result of excessive friction or mechanical interference, or j

known to be untrippable. Under the requirements of Specification 3.0.3, if more than one control rod is inoperable per 3.1.3.1.a, within one hour i

measures must be initiated to place the unit in at least STARTUP within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months .

3.0.4 This specification provides that entry into an OPERABLE CONDITION must i

components OPERABLE, and (b) all other parameters as specified in the Limiting j

condition for Operation being met without regard for allowable deviations and i

out-of-service provisions contained in the ACTION statements.

BRUNSWICK - UNIT 2 8 3/4 0-L Amendment No.

i (BSEP-2-96) 3/4.8 ELECTRICAL POWER SYSTEM 3 BASES 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 specifled independent and redundant A.C. and D.C. power sources and distribution systems satisfy the requirements of Ceneral 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 is consistent with the initial condition assumptions of the accident analyses and is based upon maintaining at least one of each of the onsite A.C. and the corresponding D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assuraed loss of offsite power and single failure of the other onsite A.C. or D.C. source.

This specification also delineates what additional conditions must be satisfied to permit operation to continue when a power source is not OPERABLE. When a diesel generator or an off-site power source to an emergency bus is inoperable, there is an additional ACTION requirement to verify that all required redundant safety systems, subsystems, trains, components, and devices, that depend on the remaining OPERA 8LE power sources 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 the safety functions of critical systems. It specifically prohibits operation when one diesel generator or one of the required off-site power sources to an emergency bus is inoperable and a redundant system, subsystem, train, component, or device powered from another diesel generator is inoperable for another reason.

The provisions of this specification permit the ACTION statements associated with individual systems, subsystems, trains, components, or devices to be consistent with the ACTION statements of the associated electrical power It allows operation to be governed by the time limits of the ACTIDW source.

statement associated with the Limiting Condition for operation for the emergency power source, not the individual ACTION statements for each system, subsystem, train, component, or device that is determined to be inoperable solely because of the inoperability of les emergency power source.

For example, Specification 3.8.1.1 requires, in part, that all four emergency diesel generators be OPERABLE. The ACTION statement provides for a 3 day out-of-service time when one emergency diesel generator is not OPERA 8LE.

If the definition of OPERA 8LE were applied without consideration of Specification 3.8.1.1 ACTION b.2, all systems, subsystems, trains, components, and devices supplied by the inoperable emergency power source would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the Limiting Conditions for Operation. However, the provlsions of Specification 3.8.1.1 ACTION b.2 permits the time limits for continued BRUNSWICK - UNIT 2 5 3/4 8-1 Amendment No.

ELECTRICAL POWER SYSTEMS BASES (Continued) operation to be consistent with the ACTION statement for the inoperable emergency diesel generator instead, provided the other specified conditions are satisfied.

If they are not satisfied, shutdown is required in accordance with this specification.

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 unit batteries are in accordance with the recommendations of the battery manufacturer and sound maintenance practices.

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 capacity 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 4.8.2.3.2-1 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 or equal to 2.13 volts and specific gravity not more than 0.015 below the manufacturer's full charge specific gravity or a bactery charger current that had stab 111:ed 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 or equal to 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.

i Operation with a battery cell's parameter outside the normal limit but within l

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 capabilicyl (2) the allowable value for the average specific gravity of all the cells, not more than 0.020 below the manufacturer's recommended full charge specific gravity ensures that the decrease in rating will be less than the safety margin provided in sizings (3) the allowable value for an indivdual cell's specific gravity ensures that an individual cell's specific gravity will not be more than 0.020 below the mantfacturer's full charge' specific gravity and that the overall capabilley of the battery will be i

maintained within an acceptable 11 mitt and (4) the allowable value for an individual cell's float voltage, greater than or equal to 2.07 volts, ensures the battery's capability to perform its design function.
