McGuire 1/ Cycle 4 0FA Reload-Peaking Factor Limit Report l

Dear Mr. Denton:

My letter of November 16, 1984 submitted proposed license amendments to facility operating licenses NPF-9 and NPF-17 for McGuire Nucicar Sta-tion, Units 1 and 2, respectively.

The proposed amendments ensure that plant operation is consistent with the design and safety evaluation conclusion statements made in the McGuire Unit 1 Cycle 4 Reload Safety Evaluation (RSE) and ensure that these conclusions remain valid.

The submittal indicated that the peaking factor limit report for McGuire Unit 1/ Cycle 4 which is required in accordance with McGuire technical specification 6.9.1.9 would be submitted at least 60 days prior to cycle initial criticality.

Unit 1 is currently in its end of Cycle 3 refuel-ing outage (which began May 16, 1986) with Cycle 4 initial criticality scheduled for July 24, 1986.

Attached is the Peaking Factor Limit Report for McGuire Unit 1/ Cycle 4.

This report provides the W(Z) functions that are to be used for RAOC and base load operation during Cycle 4, and the value f o r AP giD.

For both RAOC and base load operation, 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 informa-tion for base load operation has been obtained using a 1 5 percent AFD about a measured target in the power interval between 80% and 100% of rated thermal power.

Fi ures 1-3 are the W(Z) functions appropriate for 5

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 8606050274 86052 0\\

r PEAKING FACTOR LIMIT REPORT FOR MCGUIRE UNIT 1 CYCLE 4 RAOC AND BASE LOAD OPERATION This Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.9 of the McGuire Unit 1 Technical Specifications.

The McGuire 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 13100 MWD /MTU through the use of three point interpolation.

The McGuire Unit 1, Cycle 4 elevation dependent W(z) values for base load opertion between 80% and 100% of rated thermal power with a 5 percent AFD about a measured target value at 150, 6000, and 12000 MVD/MTU Cycle 4 burnups are shown in Figures 4 through 6, respectively.

This information is sufficient to determine W(z) versus core height for Cycle 4 burnups in the range of 0 MWD /MTU to 13100 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 B of Reference 1.

ND The minimum allowable power level for base load operation, APL, for McGuire 1 Cycle 4 is 80 percent of rated thermal 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:

Fq(z) 5 2.21 (K(Z)] for P > 0.50 and P

Fq(z) s 4.52 [K(Z)] for P s 0.50 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.
