3.0.5 Unless specifically noted, all the information provided in the Limiting Condition for Operation including the associated ACTION requirements shall apply to each unit individually. In those cases where a specification makes ) ,

reference to systems or components which are shared by both units, the affected systems or components will be clearly identified in parentheses or footnotes declaring the reference to be " common". Whenever the Limiting Condition for Operation refers to systems or components which are common, the ACTION requirements will apply to both units simultaneously. (This will be indicated in the ACTION section.) Whenever certain portions of a specification refer to systems, components, operating parameters, setpoints, etc. , which are different for each unit, this will be identified in parentheses or footnotes '

or in the APPLICABILITY section as. appropriate.

SURVEILLANCE REQUIREMENTS 4.0.1 Surveillance Requirements shall be met during the OPERATIONAL MODES or other conditions specified for individual Limiting Conditions for Operation unless otherwise stated in an individual Surveillance Requirement.

4.0.1 This specification provides that surveillance activities necessary I to ensure the Limiting Conditions for Operation are met and will be performed during the OPERATIONAL MODES or other conditions for which the Limiting Condi- ),

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

Surveillance Requirements for Special Test Exceptions need only be performed  :

when the Special Test Exception is being utilized as an exception to an individual specification. '

i 4.0.2 The provisions of this specification provide allowable toleranc2s for performing surveillance activities beyond tl.ose specified in the nominal surveillance interval. These tolerances are necessary to provide operational flexibility because of scheduling and perfomance considerations. The phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent ,

surveillance activities.

I i 4.0.3 The provisions of this specification set forth the criteria for i determination of compliance with the OPERABILITY requirements of the Limiting Conditions for Operation. Under these criteria, equipment, systems or compo--

l nents are assumed to be OPERABLE if the associated surveillance activities have '

been satisfactorily perfomed within the specified time interval. Nothing in i 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. Items may be determined inoperable during use, during surveillance tests, or in accordance with this specification.

4.0.4 This specification ensures that the surveillance activities b 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 surveil-1ance activities 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 h STARTUP or following extended plant outages, the applicable surveillance F activities must be performed within the stated surveillance interval prior to placing or returning the system or equipment into OPERABLE status.

The allowable tolerance also provides flexibility to accommodate the length of a '

fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18 month surveillance interval. It is not intended that this

)rovision be used repeatedly as a convenience to extend surveillance intervals seyond that specified for surveillances that are not performed during refueling t outages. The limitation of Specification 4.0.2 is based on engineering

• judgement and the recognition that the most probable result of any ) articular surveillance being performed is the verification of conformance wit 1 the  :

Surveillance Requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval. ,

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

Surveillance Requirements for Special Test Exceptions need only be performed when the Special Test Exception is being utilized as an exception to en individual specification. *'

4.0.2 The provisions of this specification provide allowable tolerances for performing surveillt.nce activities beyond those specified in the nominal surveillance interval. These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations. The phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent ,

surveillance activities.

The allowable tolerance also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18 month surveillance interval. It is not intended that this provtsion be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling outages. The limitation of Specification 4.0.2 is based on engineering judgement and the recognition that'the most probable result of any particular surveillance being performed is the verification of conformance with the >

Surveillance Requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance 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 these criteria, equipment, systems or compo-nents are assumed to be OPERABLE if the associated surveillance activities have been satisf actorily performed within the specified time interv'al. Nothing in-l 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. Items may be determined inoperable during use, during surveillance tests, or in accordance with this specification.

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 surveil-lance activities 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.
