Specific control bank withdrawal and overlap limits as a function of the fully withdrawn position are shown in Table 1.

2.7 Heat Flux Hot Channel Factor - FQ(XY,Z) (TS 3.2.1) 2.7.1 FQ(X,Y,Z) steady-state limits are defined by the following relationships:

F RTP *K(Z)/0.5 for P < 0.5 Q

where, P = (Thermal Power)/(Rated Power)

Note: The measured FQ(X,Y,Z) shall be increased by 3% to account for manufacturing tolerances and 5% to account for measurement uncertainty when comparing against LCO limits. The manufacturing tolerance and measurement uncertainty are implicitly included in the FQ surveillance limits as defined in COLR Sections 2.7.5 and 2.7.6.

2.7.2 F Tr =2.70 x K(BU) 2.7.3 K(Z) is the normalized FQ(X,Y,Z) as a function of core height. The K(Z) function for Westinghouse RFA fuel is provided in Figure 4.

2.7.4 K(BU) is the normalized FQ(X,Y,Z) as a function of burnup. K(BU) for Westinghouse RFA fuel is 1.0 for all burnups.

The FAH steady-state limits referred to in Technical Specification 3.2.2 is defined by the following relationship.

2.8.1 Fj,(X,Y)Lc°= MARP (X,Y)

• L.0+

--H* (1.0-P) where:

FL (X, Y) LCO is the steady-state, maximum allowed radial peak and includes allowances for calculation/measurement uncertainty.

MARP(X,Y) =

Cycle-specific operating limit Maximum Allowable Radial Peaks.

MARP(X,Y) radial peaking limits are provided in Table 3.

Thermal Power Rated Thermal Power RRH =Thermal Power reduction required to compensate for each 1% that the measured radial peak, F,* (X,Y), exceeds its limit.

(RRH = 3.34 (0.0 < P < 1.0))

The following parameters are required for core monitoring per the Surveillance requirements of Technical Specification 3.2.2.

2.8.2 FýH (X,Y) SURV FDI (X,Y) x MAI(X,Y)

UMR x TILT where:

L SURV FL (X,Y)

=

Cycle dependent maximum allowable design peaking factor that ensures F AH(XY) limit is not exceeded for operation within the SURV AFD, RIL, and QPTR limits. FL, (X,Y) includes allowances for calculational and measurement uncertainty.

MCEI-0400-261 Page 21 of 32 Revision 3 McGuire 1 Cycle 22 Core Operating Limits Report D

D FAR (X,Y) = Design radial power distribution for FAH. FAB (XY) is provided in Appendix Table A-3 for normal operation and in Appendix Table A-6 for power escalation testing during initial startup operation.

M AH(XY) =The margin remaining in core location X,Y relative to the Operational DNB limits in the transient power distribution.

MAH(X,Y) is provided in Appendix Table A-3 for normal operation and in Appendix Table A-6 for power escalation testing during initial startup operation.

UMR = Uncertainty value for measured radial peaks. (UMR = 1.0).

UMR is 1.0 since a factor of 1.04 is implicitly included in the variable MAH(X,Y).

TILT = Peaking penalty to account for allowable quadrant power tilt ratio of 1.02 (TILT = 1.035).

2.8.3 RRH= 3.34 where:

RRH = Thermal power reduction required to compensate for each 1% that the measured radial peak, F',

(X,Y), exceeds its limit. (0 < P < 1.0) 2.8.4 TRH = 0.04 where:

TRHJ=

Reduction in OTAT K1 setpoint required to compensate for each 1% that the measured radial peak, F~, (X,Y), exceeds its limit.

2.8.5 FAH(XY) penalty factors for Technical Specification Surveillance 3.2.2.2 are provided in Table 2.

The fl(AI) negative breakpoints and slopes for OTAT are less restrictive than the OPAT f2(AI) negative breakpoint and slope. Therefore, during a transient which challenges the negative imbalance limits the OPAT f2(AI) limits will result in a reactor trip before the OTAT f, (Al) limits are reached. This makes implementation of an OTAT fl (AI) negative breakpoint and slope unnecessary.

The fl (AI) "negative" breakpoints and the fl (Al) "negative" slope are less restrictive than the OPAT f2(AI) negative breakpoint and slope. Therefore, during a transient which challenges the negative imbalance limits, the OPAT f2 (AI) limits will result in a reactor trip before the OTAT fl (Al) limits are reached.

This data was generated in the McGuire 2 Cycle 21 Maneuvering Analysis calculation file, MCC-1553.05-00-0528. Due to the size of the monitoring factor data, Appendix A is controlled electronically within Duke and is not included in the Duke internal copies of the COLR. The Plant Nuclear Engineering Section will control this information via computer file(s) and should be contacted if there is a need to access this information.

Appendix A is included in the COLR copy transmitted to the NRC.
