BASES CHANGE The following Bases change is submitted as recommended by Generic Letter 89-14 and is super imposed on the bases change submitted by the Supply System in accordance with guidance provided by the Staff in Generic Letter 87-09 (Supply System letter G02-89-016). Should this request be approved by the Staff prior to approval, of the 87-09 submittal the Supply System considers that the attached Bases change is still appropriate even though the 87-09 submittal might still be in review by the Staff.

3 4.0 APPLICABILITY BASES Con't Mhen a shutdown is required to comply with ACTION requirements, the provisions of Spec'ification 3.0.4 do not apply because they would delay placing the facility in a. lower CONDITIOH of operation.

S ecifications'4.0.1 throu h '4.0.5 establish the general requirements app ica e to urve ance equ rements. These requirements are based on the Surveillance Requirements stated'in the Code of Federal Regulations, i0 CFR 50.36(c)(3):

"Surveillance requirements are requirements relatina to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions of operation will be met."

Specification 4.0.1 establishes the requirement that surveillances must be per ormed uring t e OPERATIONAL CONDITIONS or other conditions for which the requirements of the Limiting Conditions for Operation apply unless otherwise stated in an individual Surveillance Requirement. The purpose of this specification is to ensure that surveillances are performed to verify the operational status of systems and components and that parameters are within specified lim'.ts to ensure safe operation of the facility when the plant is in an OPERATIONAL CONDITION or other specified condition for which the individual Limiting Conditions for Operation are applicable. Surveillance Requirements do not have to be"performed,when the facility is in an OPERATIONAL. CONDITION for which the requirements of the, associated Limiting Condition for Opera'tion do not apply unless otherwise specified. The Surveillance Reavirements associated with a Special Test Exception are only applicable when the Special bl<<h <<h ~4 Test Exception is used as an allowable exception to the requirements of a specification.

4.0.3 Failure to perform a Surveillance Requ'irement within the specified time interval shall constitute a failure to meet the OPERABILITY requirements for a Limiting Condition for Operation. .Exceptions to these requirements are stated in the individual Specificatons. Surveillance requirements do not have to be performed on inoperable equipment.

4.0.4 Entry into an, OPERATIONAL CONDITION or ot specified applicable condition shall not be made unless the Surveill Requirement(s) associated with the Limiting Condition for Operation-have n performed within the applicable surveillance interval or as othe i specific'd.

4.0.5 Surveillance Requirements for inse~ i inspection and testing of ASME Code Class 1, 2; s 8 3 components shall b~@Ticable as follows:

a. Inservice inspection of ASM/ e Class 1, 2, and 3 components and inservice testing of ASME C Class 1, 2, and 3 pumps and valves shall be performed in ac ance with Section XI of the ASME Boiler and Pressure Vessel Co applicable Addenda as required by 10 CFR 50, Section 50.55'( , except where specific written relief has been granted by the C ission pursuant to 10 CFR 50, Section 50.55a(g)

b. Surveillance intervals specified in Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda for the inservice inspection and testing activities required by the ASME Boiler and Pressure Vessel Code and applicable Addenda shall be applicable as follows in these Technical Specifications:
