APPLICABILITY BASES RIP p" qP3 3.0.4 (Continued)

The intent of this provision is to ensure that facility operation is not initi-ated 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 speci-fications 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 ensure the Limiting Conditions for Operation are met and will be performed dur-ing the OPERATIONAL MOOES or other conditions for which the Limiting Conditions for Oper ation are applicable.

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

Survei 1-lance 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 per o llance activities beyond those specified omsnal sur-veillance interval.

ces are ne provide operational flexibilitybecause of scheduli e considerations.

The phrase "at least" associat surveillance frequency ate this allow-able t va ue and permits the performance of more frequent su The tolerance values, taken either individually or consecutively over three 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 deter mination of compliance with the OPERABILITY requirements of the Limiting Con-ditions 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 OPER-ABLE 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.

Therefore, ACTION statements are entered when the Surveillance Requirements should have been performed rather than at the time it is discovered that the tests were not performed.

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 MOOE or other applicable con-dition.

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.

SHEARON HARRIS - UNIT 1 B 3/4 0"2

The provisions of this specification establish the limit for which the specified time interval for Surveillance Requirements may be extended.

It permits an allowable 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 conditions or other ongoing surveillance or maintenance activities. It also provides flexibilityto 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 provision 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 intervaled
