1 APPLICABILITY i
i BASES l
4.0.1 This specification provides that surveillance activities necessary to ensure the Limiting Conditions for Operation are met and will be performed during the OPERATIONAL CONDITIONS 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 COND!-
TIONS or other conditions are provided in the individual Surveillance Require-ments.
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.

s The tolerance vaJues, taken either i b idually or consecutively over 3 test intervals rgr'sufficiently restrictive to enstredhat the reliability associa ad th the surveillance activity is not signific'ently\\egraded beyond d
1ba tained from the nominal specified interval.
4.0.3 The provisions of this specification set forth the criteria for determination of compliance with the OPERABILITY requirerants 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 surveillance activities associated with a Limiting Conditions for Operation have been performed within the specified time interval prior to entry into an applicable OPERATIONAL CONDITION or other specified applicability condition. The intent of this provision is to ensure that surveillance 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 outage, the applicable surveillance activ-ities must be performed within the stated survtA11ance interval prior to placing or returning the system or equipment into OPERABLE status.
i FERMI - UNIT 2 B 3/4 0-2
o-It6PJT PAGE B 3/4 0-2 4.0.2 Specification 4.0.2 establishes the limit for which the specified tine interval for Surveillance Boquirenents ney be extended. It permits an allowab.le extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the surveillance; e.g., transient conditjons or other ongoing surveillance or maintenance activities. It also provides flexibility to accomnodate the i
length of a fuel cycle for surveillances that are performed at~
czch refueling outage and are specified with an 18-nonth surveillance interval. It is not intended.that this provision be used repeatcdly as a convenience to exteni 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 judgenent and the recognition that the nost probable result of any particular surveillance being perforned is the verification of conformance with the Surveillance Beguirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degra3ed beyond that obtained from the specified surveillance interval.
