F p *K(Z)IP for P > 0.5 F r7 *K(Z)/0.5 for P < 0.5
- where, P = (Thermal Power)/(Rated Power)
Note: The measured FQ(X,YZ) 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 FR =2.60 x K(BU) 2.7.3 K(Z) is the normalized FQ(X,YZ) 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,YZ) as a function of bumup. K(BU) for Westinghouse RFA fuel is 1.0 for all burnups.

UMT = Total Peak Measurement Uncertainty. (UNIT = 1.05)
MT = Engineering Hot Channel Factor. (MT = 1.03)
TILT = Peaking penalty that accounts for the peaking increase from an allowable quadrant power tilt ratio of 1.02. (TILT = 1.035) 2.7.6 FL(X,Y,Z)'
=
FQ(XY,Z)
- MC(X,Y,Z)
UNIT
- TILT where:
FQ(X,Y,Z)RPS =

TILT = Peaking penalty that accounts for the peaking increase for an allowable quadrant power tilt ratio of 1.02. (TIT = 1.035) 2.7.7 KSLOPE = 0.0725 where:
KSLOPE is the adjustment to the K1 value from OTAT trip setpoint required to RPS compensate for each 1% that F." (X,YZ) exceeds FQ (X,Y,Z) 2.7.8 FQ(X,YZ) penalty factors for Technical Specification Surveillance's 3.2.1.2 and 3.2.1.3 are provided in Table 2.

2.8.1 FAL, (X, Y)"co = MARP (X,Y) * [10+
I
- (1.0 - P)]
where:
FL (XY)'C is defined as the steady-state, maximum allowed radial peak.
FH (X, Y)Lco 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, FH (X,Y), exceeds the limit. RRH also is used to scale the MARP limits as a function of power per the FL (X, Y)Lco equation. (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 FL. (X,Y)
= FH(X,Y)xMA,(X,Y)
UMR x TILT where:
FH (XY)SURV =
Cycle dependent maximum allowable design peaking factor that ensures that the FAH(X,Y) limit will be preserved for operation within the LCO limits. FISH (XY) includes allowances for calculation-measurement uncertainty.
MCEI-040046 Page 21 of 32 Revision 28 McGuire 1 Cycle 18 Core Operating Limits Report FH (XY) = Design radial power distribution for FM Fffl (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.
M,,H(XY) = The margin remaining in core location X,Y relative to the Operational DNB limits in the transient power distribution.
MMH(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 is set to 1.0 since a factor of 1.04 is implicitly included in the variable MH (X,Y).
TILT = Peaking penalty that accounts for the peaking increase for an 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, FSH (X,Y) exceeds its limit. (0 < P < 1.0) 2.8A TRH = 0.04 where:
TRH =
Reduction in OTAT K1 setpoint required to compensate for each 1% that the measured radial peak, FH (X,Y) exceeds its limit.

The fl(Al) negative breakpoints and slopes for OTAT are less restrictive than the OPAT f2(Al) 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 f1 (Al) limits are reached. This makes implementation of an OTAT fI(Al) negative breakpoint and slope unnecessary.
