B.J. Youngblood, Director PWR Project Directorate #4 Subj,ect: McGuire Nuclear Station, Unit 2 Docket No. 50-370 McGuire 2/ Cycle 3 Reload-Peaking Fc: tor Limit Report
Dear Mr. Denton:
1 The McGuire Unit 2 end of cycle 2 refueling outage is currently scheduled to begin March 14, 1986, with a cycle 3 startup (initial criticality) date of May 16,1986. This reload is expected to be accomplished under the provisions of 10 CFR 50.59.
Pursuant to Technical Specification 6.9.1.9, attached is the Peaking Factor Limit Report for McGuire Unit 2/ Cycle 3.
This report provides the W(Z) functions that are to be used for RAOC and base load operation'during Cycle 1
3, and the value for APLND. 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-j 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, 'a(z),
will be limited to the values specified in the Technical Specifications.
Very truly yours,
)hhE$.

PEAKINC FACTOR LIMIT REPORT FOR McGUIRE UNIT 2 CYCLE 3 RAOC AND BASE IDAD OPERATION This Peaking Factor Limit Report is provided in acccrdance with Paragraph 6.9.1.9 of the McGuire Unit 2 Technical Specifications.
The McGuire Unit 2 Cycle 3 elevation dependent V(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 3 burnups in the range of 0 MWD /MTU to 11000 MVD/MTU through the use of three point interpolation.
The McGuire Unit 2 Cycle 3 elevation dependent W(z) values for base load operation between 80% and 100% of rated thermal power with a 5 percent AFD about a measured target value at 150, 6000, and 10000 MWD /MTU Cycle 3 burnups are shown in Figures 4 thrmigh 6 respectively.
This information is sufficient to determine W(z) versus core height for Cycle 3 burnups in the range of 0 MWD /MTU to 11000 MWD /MTU throegh 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.
The minimum allowable power level for base load operation, APL, for McGuire 2 Cycle 3 is 80 percent of rated thermal power.
The appropriate V(z) function is used to confirm that the heat flux hot channel factor, Fq(z), will be limited to the Technical Specification values of:
4 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 10CFR10.46.
