Dear Mr. Wyke:

CATAWBA NUCLEAR STATION UNIT 1 CYCG 4 PFIR f

l Attached is the Peaking Factor Limit Report for Catawba Unit 1

[

Cycle 4.

This report transmits' the W(z) functions that are to be

{

used for RAOC operation during Cycle 4.

For RAOC operation, a set of

-t data coverirq thra specific burnup steps is provided which permits the determination of W(z) at any cycle burnup through the use of

)

three point interpolation.

i j

Figures 1-3 are the W(z) functions appropriate for RAOC operation.

All of these W(z) values have been independently verified.

l i

The W(z) functions for Base load Technical Specification are not i

being supplied as per Duke Power request.

PEAKING FACTOR LIMIT REPORT FOR CATAWBA UNIT 1 CYCLE 4 RAOC OPERATION This Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.9 of the Catawba Unit 1 Technical Specifications.

The Catawba Unit 1 Cycle 4 elevation dependent W(z) values for RAOC operation at beginning, middle, and near end-of-life are shown in Figures 1 through 3, respectively.

This information is sufficient to determine W(z) versus core height for Cycle 4 burnups in the range of 0 MWD /MTU to 13850 MVD/MTU through the use of three point interpolation.

W(z) values for RAOC operation were calculated using the method described in Part B of Reference 1.

The appropriate W(z) function is used to confirm that the heat flux hot channel factor, Fq(z), will be limited to the Technical Specification values of:

l (K(z)] f r P > 0.50 and Fq(z) $

Fq(z) $ 4.64 [K(z)] for P $ 0.50 l

l The appropriate elevation dependent W(z) values, when applied to a power distribution measured under equilibrium conditions, demonstrates that the initial conditions assumed in the LOCA are met, along with the ECCS acceptance criteria of 10CFR50.46.
