McGuire Nuclear Station Unit 2 Docket No. 50-370 4
McGuire 2/ Cycle 5 Reload-Peaking Factor Limit Report 1
Centlement i
no McGuire Unit 2 end of cycle 4 refueling outage has been completed with cycle 5 I
startup (initial criticality) achieved on July 26, 1988.
nis reload was accomplished under the provisions of 10CFR 50.59.
I Pursuant to Technical Specification 6.9.1.9 attached is the Peaking Factor Limit L
Report for McCuire Unit 2/ Cycle 5.
This repcrt provides the W(Z) functions that are to be used for RAOC operation during cycle 5.
Note that no Base Load operatson analysis was performed for this eyeg, and therefore the W(Z) functions for Base Ioad operation and the value for APL are not being provided. For RAOC d
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 i
point interpolation.
Figures 1-3 are the W(Z) functions appropriate for RAOC operation.
The appropriate W(Z) function is used to confirm that the heat flux hot channel factor, Fq(s), will be limited to the values specified in the l
Technical Specifiestions.
Very truly yours, i

f PEAKING FACTOR LIMIT REPORT POR MCCUIRE UNIT 2 CYCLE,5 RAOC OPERATION This Peaking Factor Limit Report is provided in accordance with Paragraph 6.9.1.9 of the McGuire Unit 2 Technical Specifications.
The McGuire Unit 2 Cycle S elevation dependent V(z) values for RAOC operation at beginning,saiddle, and near end of-life are shown in Figures 1 through 3, respectively. This information is sufficient to determine V(z) versus core height for Cycle 5 burtups in the range of 0 L*D/MTV to 13500 $*D/MTV through the use of three point interpolation.
V(z) values for PAOC operation were calculated using the method described in Part B of Reference 1.
The appropriate V(z) function is used to confirm that the heat flux hot channel factor, Fq(z), vill be limited to the Technical Specification values of:
[K(z)) for P > 0.50 and Fq(z) $
Fq(z) $ 4.64
[K(:)) for P $ 0.50 The appropriate elevation dependent V(z) values, when applied to a power distribution measured under equilibriu:n conditions, demonstrates that the initial conditions assumed in the 1DCA are met, along with the ECCS acceptance criteria of 10CFR50.46.
