Subject:

Catawba Nuclear Station Docket No. 50-413 Unit 1 Cycle 3 Peaking Factor Limit Report Technical Specification 6.9.1.9 Gentlemen:

. Pursuant to Technical Specification 6.9.1.9, please find attached the Radial Peaking Factor Limit Report for Catawba Nuclear Station, Unit 1 Cycle 3. The enclosed Peaking Factor Limit Report provides the W(z) functions that are to be used for RAOC and base load operation during Cycle 3. A set of data covering three specific'burnup steps is provided which permits the determination of W(z) at any cycle burnup through the use of three point interpolation. The information for base load operation has been obtained using, a i 5 percent AFD about a measured target in the power interval between 80% and 100% of rated thermal power. The base load operation W(z) is also conservative for a 3 percent AFD about a' measured target. Figures 1-3 are the W(z) functions appropriate for RA00 operation and Figures 4-6 are the W(z) functions appropriate

-for base load operation. All of~these W(z) values have been independently verified.

The Unit 1 End-of-Cycle 2 refueling outage is scheduled for October 2, 1987 with Cycle 3 initial criticality scheduled for' December 1, 1987.

Very truly yours, pf -

, RAOC AND BASE LOAD OPERATION h '

This Peaking Factor 1imit Report is provided in accordance with Paragraph 6.9.1.9 of the Catawba Unit 1 Technical Specifications, The Catawba Unit 1 Cycle 3 elevation dependent W(z) values fer RAOC operation,At beginning, . middle, and near end-of-life are shown in Figures 1 through 3, respective ly. This information is sufficient to

,~

to determina _ W(74 versus core height for Cycle 3 burdups in the range of 0 MWD /MTU )o'13000 MWD /MTU tirough the use of three point inte rpolation. 6 The' Catawba Unit 1 Cycle 3 elevation dependent W(z) values for base load operation between 80% exd 100% of rated thermal power consistent with the Catawba Unit 1 technical specification 4.2.2.1.3 at 150, 6000, and 12000 MWD /MTU Cycle 3 burnups are shown in Figures 4 through 6, respectively. This information is sufficient to determine W(z) versus core height for Cycle 3 burnupe,in the range of 0 MWD /MTU to 13000

[. MWD /MTU through the use of three point interpolation.

\

W(z) values for RACC and base load operation were calculated using the method described in Pa'rt B of Reference 1.

D The minimum allevablo power level for base load operation, APL , for t f . Catawba 1 Cycle 3 is 80 percent of ratad . thermal power.

J The appropriate W(z) function,ts used to confirm that the heat flux hot t' ,

,4 channel factor, Fq(z), will ha limited to the Technical Specification values of:

2 1A g 7 g) p [K(z)] for P > 0.50 and s

Fq(2) $ 4.64 (K(z)] for P $ 0.50 s

1 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 l ECCS acceptance criteria of 10CFR50.46, 1
