Subject:

Catawba Nuclear Station, Units 1 and 2 Docket Nos. 50-413 and 50-414 Unit 1/ Cycle 5 and Unit 2/ Cycle 3 Coro Operating Limits Reports Gontlement By letter dated May 17, it)0 the NRC issued Amendment Nos. 74/68 to  !

Facility Operating Licenses NPF-35 and NPF-52 for Catawba Nuclear Station Units 1 and 2, respectively. These amendments remove certain  ;

cycle-specific parameter limits from the Technical Specifications and relocate them to a " Core Operating Limits Report" (COLR). Technical l Specification 6.9.1.9 as revised by those amendments requires that the COLR, including any mid-cycle revisions or supplements thereto, shall be provided upon issuance, for each reload cycle, to the NRC Document Control Desk with copics to the Regional Administrator and Resident inspector.

Accordingly, pursuant to Technical Specificatioti 6.9.1.9 (and 10 CFR 50.4),

attached are the Core Operating Limits Reports for Catawba Unit 1/ Cycle 5 and Catawba Unit 2/ Cycle 3. These reports document the Core Operating Limits which are determined so that all applicable limits (e.g. fuel ,

thermal-mechanical limits, core thermal-hydraulic limits, ECCS limits, nuclear limits such as shutdown margin, and transient and accident analysis limits) of the Safety Analysis are met. Note that no base load operation ,

analysis was performed for Unit 1/ Cycle 5 or Unit 2/ Cycle 3, and therefore i the axial fluNDdifference target band during base load operation, the value for APL , and the W(z) functions for base load operation are not being provided (ref. COLR Sections 2.4'and 2.5).

These are the initial COLRs on Catawba Units 1 and 2, and are being issued / submitted at this time due to the recent License Amendment approval cited above.
