APPLICABILITY' LIMITING CONDITION FOR OPERATION (Continued) 3 3.0.5 Unless specifically noted, all the information provided in the Limiting ,
Condition for Operation including the associated ACTION requirements shall 1 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 ;
declarino the reference to be "commen". Whenever the Limiting Condition for !
Operation refers to systems or components which are common, the ACTION 4 requirements will apply to both units simultaneously. (This will be indicated in the ACTION section.) Whenever certain portions of a specification refe- to systems, components, operating parameters, setpoints, etc., which are 1 different for each unit, this will be identified in parentheses or footnotes or in the APPLICABILITY section as.apprnpriate.

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 sp'ecification provides that surveillance activities necessary to' ensure the Limiting Conditions for Operation are met and will be performed-during the OPERAT10NAL 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 MODES or other conditions are prcvided 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.
4.0.2 The provisions of this specification provide allowable tolerances for performing surveillance activities beyond those_specified in the nominal surveillance interval. These tolerances are necessary to provide operational '
i 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 tolerance values, taken either individually or consecutively over three test intervals, are sufficiently restrict.ve to ensure that the reliabil-ity associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval.

4.0.4 This specification ensures TN M at 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 o' this provision is to ensure that surveil- .
lance activities have been satisfactorily demonstrat.ed on a current basis as l required to meet the OPERABILITY requirements of the Limiting Condition for l Operation.
Under the terms of this specification, for example, during initial plant l' STARTUP or following extended plant outages, the applicable surveillance l activities must be performed within the stated surveillance interval prior to l placing or returning the system or equipment into OPERABLE status.

INSERT "B" This specification establishes the failure to perform a Surveillance Requirement within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, as a condition that constitutes a failure to meet the OPERABil.lTY requirements for a Limiting Condition for Operation. Under the provisions of this specification, systems and components are assumed to be. i OPERABLE when Surveillance Requirements have been satisfactorily performed within the specified time interval. However, nothing in this provision is to be construed as implying that systems or components are OPERABLE when they are .
found or known to be inoperable although still meeting the Surveillance Requirements. This specification also clarifies that the ACTION requirements are applicable when Surveillance Requirements have not been completed within the allowed surveillance interval and that the time limits of the ACTION requirements apply from.the point in time it is identified that a surveillance has not been performed and not at any time that-the allowed surveillance interval was exceeded. Completion of the Surveillance Requirement within the ,
allowable (equipment inoperability) outage time limits of the ACTION !
requirements restores compliance with the requirements of Specification 4.0.3.
However, this does not negate the fact that the failure to have performed the surveillance within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, was a violation of the OPERABILITY requirements of a Limiting Condition for Operation that is subject to enforcement action, i further, the failure to. perform a surveillance within the provisions of:
Specification 4.0.2 is a violation of a Technical Specification requirement and is, therefore, a reportable event under the requirements of 10 CFR 50.73(a)(2)(1)(B) because it is a condition prohibited by the plant's Technical Specifications.
If the allowable (equipment inoperability) outage time limits of the ACTION requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or a shutdown is raquired to comply with ACTION requirements, e.g., Specification 3.0.3, a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> allowance is provided <
r to permit a delay in implementing the ACTION requirements. This provides an '
I adequate time limit to complete Surveillance Requirements that have not been ;
I performed. The purpose of this allowance is to permit the' completion of a i surveillance before a shutdown is required to comply with ACTION requirements or before other remedial measures would be required that may preclude completion of a surveillance. The basis for this allowance includes consideration for plant .'
conditions, adequate planning, availability of personnel, the time required to .
! perform the surveillance, and the safety significance of the delay in completing ;
l the required surveillance. This provision also provides a time limit for the completion of Surveillance Requirements that become applicable as a consequence of MODE changes imposed by ACTION requirements and for completing Surveillance
! Requirements that are applicable when an exception to the requirements of
! Specification 4.0.4 is allowed, if a surveillance is not completed within the l- 24-hour allowance, the time limits of the ACTION requirements are applicable at 1 that time. When a surveillance is performed within the 24-hour allowance and i the Surveillance Requirements are not met, the time limits of the ACTION requirements are applicable at the time that the surveillance is terminated.
, Surveillance Requirements do not have to be performed on inoperable equipment l
because the ACTION requirements define the remedial measures that apply.
However, the Surveillance Requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABLE status.
