'. PLICABILITY 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. I This specification defines the applicability of each specification in terms of defined OPERATIONAL MODES or other specified conditions 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 The specification delineates the measures to be taken for those circumstances not directly provided for in the ACTION Statements and whose occurrence would violate the intent of a specification.

For example, Specification 3.5. 2 requires two independent ECCS Subsystems to be OPERABLE and provides explicit ACTION requirements if one ECCS Subsystem is inoperable.

Under the requirements of Specification 3.0.3, if both the required ECCS Subsystems are inoperable, within one hour measures must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , and in at least HOT SHUTDOMN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months .

As a further example, Specification 3.6.2. 1 requires two Containment Spray Systems to be OPERABLE and provides explicit ACTION requirements if one Spray System is inoperable.

Under the requirements of Specification 3.0.3 if both the required Containment Spray Systems are '.noperable, within one hour -measure must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , in at least HOT SHUTDOlr'N 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 hcurs.

3.0.4 This specification provides that entry into an OPERATIONAL MODE or other specified applicability condition must be made with (a) the full comple-ment of required

systems, equipment or comoonents OPERABLE and {b) all other parameters as specified in the Limiting Conditions for Operation being met withou. regard for allowable deviations and out of service provisions contained in the ACTION statements.

The intent of this provision is to insure that faci li y operation is not ini'iated with either required equipment or systems inoperable or other specified limits being exceeded.

Exceptions to this provision have been provided for a limited number of specifications when startup with inoperable equipment would noi affect plant safety.

These exceptions are stated in the ACTION statements of the appropriate spec.f~cations.

APPLICABILITY BASES

3. 0. 5 This specification delineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION state-ments for power

sources, when a normal or emergency power source is not OPERABLE. It specifically prohibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem,

train, component or device in another division is inoperable for another reason.

The provisions of this specification permit the ACTION statements associa.ed with individual systems, subsystems,

trains, components, or devices to be"

. consistent with ihe 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 normal'r emergency power source, not the individual ACTION statements for each

system, subsystem,

train, component or device that is determined to be inoper-able solely because of. the inoperability of its normal or emergency power source.-

For example, Specification 3.8. 1. 1 requires in part that two emergency diesel generators be OPERABLE.

The ACTION statement provides for a 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months out-of-service time when one emergency diesel generator is not OPERABLE.

If the definition of OPERABLE were applied without consideration of Specification 3.0.5, 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 applicable Limiting Condi ions for Operation.

However, ihe provisions of Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTION statement for the inoperable emergency diesel generator

instead, provided the other specified conditions are satisfied.

In this case, this would mean that the corresponding normal power source must be OPERABLE, and all redundant

systems, subsystems,

trains, components, and devices must be OPERABLE, or otherwise satisfy Specification 3.0.5 (i.e.,

be capable of performing their design function and have at least one normal or one emergency power source OPERABLE).

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

As a further example, Specification 3.8. 1. 1 requires in part that two physically independent circuits between the offsite transmission network and ihe onsi te Class IE distribution system be OPERABLE'.

The ACTIOH statement provides a

24-hour out oi service time when both required offsite circuits are not OPERABLE.

If the definition of OPERABLE were appl ied wi hout consideration of Specification 3.0.:", all systems, subsvstems,

trains, components and devices supplied by the inoperable normal power

sources, both of the offsite circuits, would also be inoperable.

.This would dictate invoking the applicable ACT:OH statements for each of the applicable LCOs.

However, ihe provisions of Specification 3.0.5 permit the time limits for con inued opera.ion to be consis =ent with the A Idyll I I ~ I Mv V.'i B 3/-': 0-2

APPLICABILITY BASES 3.0.5 (Continued)

ACTION statement for the inoperable norma'i power sources

instead, provided the

'other specified conditions are satisfied.

In this case, this would mean that for one division the emergency power source must be OPERABLE (as must te the components supplied by the emergency power source) and all redundant

systems, subsystems,

trains, components and devices in the other division must be OPERABLE, or likewise satisfy Specification

3. O. 5 (i. e.,

be capable of

. performing their design functions and have an emergency power source OPERABLE).

In other words, both emergency power sources must be OPERABLE and all redundant

systems, subsystems,

trains, components and devices in both divisions must also be OPERABLE.

If these conditions are not satisfied, action is required in accordance with this specification; In YiODES 5 or 6, Specification 3.0.5 is,not applicable, and thus the individual ACTION statements for each applicable Limiting Condition for Operation in these MODES must be adhered to.

APPLICABILITY BASES 4.0.~

This soecification provides that surveillance activities necessary to insure the Limiting Conditions for Operation are met and will be performed during the OPERATIONAL MODES or other conditions for which the Limiting Conditions for Operation are applicable.

Provisions for additional surveillance activities to be performed without regard to the applicable OPERATIONAL MODES or other conditions are provided in the individual Surveillance Requirements.

4.0.2 The provisions of this specification provide allowable tolerances for performing surveillance activi ties beyond those specified in the nominal surveillance interval.

These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations.

The tolerance

values, taken either individually or consecutively over 3

test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that, obtained from the nominal specified interval.

4.0.3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation.

Under this criteria, equipment, systems or components are assumed to be OPERABLE if-the associated surveillance activities have been satisfactorily performed within the specified time interval.

Nothing in this provision is to be construed as defining equipment, systems or components

OPERABLE, when such items are found or known to be inoperable although still meeting the Surveillance Requirements.

4. 0. 4 This specification ensures that the surveillance activities associated with a Limiting Condition for Operation have been performed within the specified time interval prior to entry into an OPERATIONAL MODE or other applicable condition.

The intent of this provision is to ensure that survei 1-lance activi ties have been satisfactorily demonstrated on a current basis as required to meet the OPERABILITY requirements of the Limiting Condition for Operation.

Under the terms of this specification, for example, during initial plant startup or following extended plant outages, the applicable surveillance activities must be performed within the stated surveillance interval prior to placing or returning the system or equipment into OPERABLE status.

3.0

~ 1 This specification defines the applicability of each specification in terms of defined OPERATIONAL ltODES or other specified conditions 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 The specification delineates the measures to be taken for those circumstances not directly provided for in the ACTION Statements and whose occurrence would violate the intent of a specification.

For example, Specifica-tion 3. 5. 2 requires two independent FCCS Subsystems to be OPERABLE and provides explicit ACTION requirements if one ECCS Subsystem is inoperable.

Under the requirements of Specification 3.0.3, if both the. required ECCS Subsystems are inoperable, within one hour measures must be initiated to place the unit in at least HOT STANDBY within the.next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , and in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months .

As

a. further example, Specification 3.6.2. 1 requires two Containment Spray Systems to be OPERABLE and provides explicit ACTION reouirements if one Spray System is inoperable.

Under the requirements of Specification 3.0.3 if both the required Containment Spray Systems are inoperable, within one hour measure must be initiated to place the unit in at least HOT STANDBY 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 COLO SHUTDOMN within the subsequent 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

3.0.4 This specification provides that entry into an OPERATIONAL NODE or other specified applicability condition must be made with (a) the full comple-ment of required

systems, equipment or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allo~able deviations and out of service provisions con-tained in the ACTION statements.

The intent of this provision is to insure that facility operation is not initiated with ei her required equipment or systems inoperable or other specified 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 safety.

These exceptions are stated in the ACTION statements of the appropriate spec',fications.

APPLICABILITY BASES 3.0.5 This specification delineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION state-ments for power sources, when a normal or emergency power source is not OPERABLE.

It specifically prohibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem,

train, component or device in another division 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'CTION 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 normal.

or emergency power

source, not the individual ACTION statements for each

system, subsystem,

train, component or device that is determined to be inoper-able solely because of the inoperability of its normal or emergency power source.

~

For example, Specification 3.8. 1. 1 requires in part that two emergency diesel generators be OPERABLE.

,The ACTION statement provides for a 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months out-of-service time when one emergency diesel generator is not OPERABLE.

If the definition of OPERABLE were applied without consideration of Specification 3.0.5, all systems, subsystems,

trains, components and devices supplied by the inoperable emergency power source would also be inoperable.

This would dictate i rvoking the applicable ACTION statements for each of, the applicable Limiting Conditions for Operation.

However, the provisions of. Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTION statement, for the inoperab'}e emergency diesel generator

instead, provided the other specified conditions are satisfied.

In this case, this would mean that the corresponding normal power source must be

OPERABLE, and all redundant

systems, subsystems,

trains, components, and devices must be OPERABLE, or otherwise satisfy Specification 3.0.5 (i.e.,

be capable of performing their design function and have at least one normal or one emergency power source OPERABI E).

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

As a further example, Specification 3.8. 1.~ requires in part that two physi-cally independent circuits between the offsite transmission network and the ansi e Class IE distribution system be OPERABLE.

The ACT:ON statement provides a 24-hour out-of-service time when both required offsite circuits are not OPERABLE.

Ii the definition of OPERABLE were applied without consideration of Speci =ication 3. 0.5, all systems, subsys

.ems,

rains, components and devices supplied by the inoperable normal power sources, both of the offsite circuits, would also be inoperable.

This would dictate invokino the applicable ACTION statemen s for each of the applicable LCOs.

'instead, provided the other specified conditions are satisfied.

In this case, this would mean that for one division the emergency power source must be OPERABLE (as must be the components supplied by the emergency power source) and all redundant

systems, subsystems,

trains, components and devices in the other division must be OPERABLE, or likewise satisfy Specification

3. 0. 5 (i. e.,

be capable of'performing their design functions and have an emergency power source OPERABLE).

In other words, both emergency power sources must be OPERABLE and all redundant

systems, subsystems-,

trains, components and devices in both divisions must also be OPERABLE.

If these conditions are not satisfied, action is required in accordance with this specification.

In HODES 5 or 6, Specification 3.0.5 is not~applicable, and thus the individual ACTION statements for each applicable Limiting Condition for Operation in these HODES must be adhered to, 4.0. 1 This specification provides that surveillance activities necessary to insure the Limiting Conditions for Operation are met and wi 11 be performed during the OPERATIONAL HODES or other conditions for which the Limiting Conditions for Operation are applicable.

Provisions for additional surveil-lance activities to be performed without regard to the applicable OPERATIONAL HODES or other conditions are provided in the individual Surveillance Requirements.

4.0. 2 The provisions of this specification provide allowable tolerances for performing surveillance 'activi ies beyond those specified in the nominal surveillance interval.

These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations.

The tolerance

values, taken either individually or consecutively over 3

test intervals, are sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval.

4.0.3 The provisions of this specification set for th the criter.'a for determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation.

Under this criteria, equipment, systems or components are assumed o be OPERABLE if the associated surveillance activities have been satisfactorily performed within the specified time interval.

Nothing in this provision is to be construed as defining equipment, systems or components OPERABLE, when such items are found or known to be inoperable although still meet inig the Surveillance Requirements.

rt

APPLICABILITY BASES 4.0.4 This specification ensures that the surveillance activities asso-ciated with a Limiting Condition for Operation have been performed within the spec'.fied time interval prior to entry into 'an OPERATIONAL MODE or other applicable condition.

The intent of this provision is to ensure that surveil-lance activities have been satisfactorily demonstrated on a current basis as required to meet the OPERABILITY requirements of he Limiting Condition for, Operation.

Under the terms of this specification, for example, during initial plant startup or following extended plant outages, the applicable surveillance activities must be performed within the stated surveillance interval prior to placing or returning the system or eouipment into OPERABLE status.

4.0.5 This specification ensures that inservice inspection of ASME Code Class k,

2 and 3 components and inservice testing of ASME Code Class 1,

2 and 3 pumps and valves will be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.55a.

Relief from any of the above requirements has been provided in writing by the Commission and is not a part of these technical specifications.

This specification includes a clarification of the frequencies for perform-ing the inervice inspection and testing activities required by Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda.

This clarifi-cation is provided to ensure consistency in surveillance intervals throughout these technical specifications and to remove any ambiguities relative to the frequencies for performing and the required inservice irspection and testing activities.

Under the 'erms of this specification, the more restrictive requirements of the Technical Specifications take precedence over the ASME Boiler and Pressure Vessel Code and applicable Addenda.

For example, the requirements of Specification

4. 0 '

to perform surveillance activities prior to entry into an OPERATIONAL MODE or other specified applicability condition takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows pumps to be tested up to one week after return to normal operation.

And, for example, the Technical Specification definition of OPERABLE does not grant a grace period before a device that is not capable of performing its soecified function is declared inoperable and takes precedence over the ASME Boiler and Pressure Vessel Code provision which allows a valve to be incapable of performing its specified function for up to 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months before being declared inoperable.
