APPLICABILITY. ,

(  ;

BASES-

- The intent of_this provision is to ensure that facility operation is not i initiated with either required equipment or systems inoperable or otler 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 specifications.

4.0.1 This specification 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 Condi-tions for Operation are applicable. Provisions for additionalLsurveillance activities,to be performed without> regard'to the applicable OPERATIONAL' MODES or other conditions are provided in the individual Surveillance Requirements. 5 L

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. '

L 4.0.3 The provisions of this specification set forth t5e' criteria for

?determi~ nation of compliance with the OPERABILITY requirements of the-Limiting Conditions for Operation. Under these 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. Items may be determined inoperable during use, during surveillance tests or in accordance with-this specifica-i tion.. Therefore, ACTION statements are entered when the Surveillance Require-

, . ments; should have been performed rather than at the time it is discovered

- that the tests were not performed.

L 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 {

J L Specification 4 '. 0 . 2 establishes the limit for which- the specified L time interval for Surveillance Requirements may be extended.- It permits,an allowable extension of- the normal ' surveillance interval to ' facilitate L

surveillance scheduling and consideration of plant operating conditions that L .may not be suitable for conducting the surveillances e.g., transient conditions or other ongoing surveillance or maintenance activities. It also

~

L j provides flexibility to accommodate the' length of a fuel cycle for- ,

l surveillances that are performed at each= refueling outage and are specified- ,

D = with an 18 month surveillance interval. It is not intended that- this L . provision be- used repeatedly as a convenience _to: extend survefilance' ,

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 L any. particular survalliance being performed is. the verification of .

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