2.7.1 F6Lj(X, Y)Lc" = MARP (X,Y)* 1.0 + RRH (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.

P Thermal Power Rated Thermal Power RRH = Thermal Power reduction required to compensate for each 1% that the measured radial peak, FM1 (X,Y), exceeds its limit. RRH also is used to scale the MARP limits as a function of power per the F*L (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.

2.7.2 F) 1 (X,Y)SURV = -D(Xy)XMAH(XY)

UMR x TILT where:

F AH (X-Y (X,Y) SURv Cycle dependent maximum allowable design peaking factor that ensures the Far I(X,Y) limit will be preserved for operation within the LCO limits. FALH (X,Y)sURv includes allowances for calculation/measurement uncertainty.

MCEI-0400-295 Page 20 Revision 1 McGuire 2 Cycle 23 Core Operating Limits Report FD FD FAH (X,Y) = Design radial power distribution for FnH. Fam (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.

MAH(X,Y) = 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 MAII(X,Y).

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

2.7.3 RRH = 3.34 where:

RRH =Thermal power reduction required to compensate for each 1% that the measured radial peak, F2H (X,Y) exceeds its limit. (0 < P < 1.0) 2.7.4 TRH = 0.04 where:

TRH = Reduction in the OTXT K1 setpoint required to compensate for each 1%

that the measured radial peak, FA", (X,Y) exceeds its limit.

2.7.5 FAH (X,Y) penalty factors for Technical Specification Surveillance 3.2.2.2 are provided in Table 2.

The fl(Al) "negative" breakpoints and the fI(AI) "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 f 2 (AI) limits will result in a reactor trip before the OTAT fl(AI) limits are reached. This makes implementation of the OTAT fl(Al) negative breakpoint and slope unnecessary.
