Subject:

McGuire Nuclear Station Docket Nos.-50-369 and 50-370 McGuirc 2/ Cycle 2 0FA Reload-Peaking Factor Limit Report

Dear Mr. Denton:

.My' letter of November 16, 1984 submitted proposed license amendments to facility operating licenses NPF-9 and NPF-17 for McGuire Nuclear Station,

' Units 1 and 2, respectively. The amendments change plant operating limitations given.in the Technical Specifications affected by use of the optimized fuel

- assembly (OFA) fdesign for.McGuire Unit 2/ Cycle 2 to ensure plant operation

~

consistent with-the design end safety evaluations. The submittal indicated that the peaking factor limit report which is required in accordance with the proposed McGuire Unit 2 technical specification paragraph 6.9.1.9 (as .given in Attachment 1 of the. submittal) would be submitted by December 14, 1984.

-Attached is the Peaking Factor Limit Report for McGuire Unit 2/ Cycle 2. This report provides the' W(Z) functions that are to 'be ugd for RAOC and base load operation'during Cycle 2,and the.value for APL '. For both RAOC and base load operation, a set of data covering three specific burnup steps is provided which permits the dctermination 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 5 percent AFD about a measured target in the power

~ interval between 80% and 100% of rated thermal power. Figures 1-3 are the W(Z) functions appropriate for RAOC operation and Figures 4-6 are the W(Z)

. functions appropriate for base load operation. The appropriate W(Z) function

~

is used to confirm that the heat flux hot channel factor, Fq(z), will be

. limited.to the values specified in the Technical Specifications.

Very.truly yours,-

Hal B. Tucker PBN:mj f .

._ .i PEAKING FACTOR LIMIT REPORT FOR MCGUIRE UNIT 2 CYCLE 2 l RAOC AND BASE LOAD OPERATION H

This' Peaking Factor Limit Report is provided in accordance with Paragraph _6.9.1.9 of the McGuire Unit'2 Technical Specifications.

TheMcGuireUnit'2,-Cycle 2elevationdependentW(z)valuesforRAOC 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 2 burnups in the range of 0

. MWD /MTU to 10700 MWD /MTU through the use of three point interpolation.

The~McGuire Unit 2, Cycle 2 elevation dependent W(z) values for base load operation between 80% and 100% of rated thermal power with a 25 percent AFD about a measured target value-at'150, 4000, and 9000 MWD /MTU Cycle 2 burnups are shown in Figures.4 through 6 respectively. This information is sufficient to determine W(z) versus core height fnr

_ Cycle 2 burnups in the range of 0 MWD /MTU to 10700 MWD /MTU through the use of_three point interpolation.

W(z) values for RAOC and base load operation were calculated using the method described in Part 8 of Reference 1.

~

ND The minimum allowable power level for base load operation, APL , for McGuire 2 Cycle 2 is 80 percent of rated thennal power.

-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:

1 -

Fq(z)1 [K(z)] for P > 0.50 and Fq(z) 3 4 52 [K(z)] for P S 0.50 L

3 l

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