l 2.0 OPERATING LIMITS The cycle specific parameter limits for the LCOs specified in Section 1.0 are i
presented in the subsections which follow. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.6.1.F.
6 2.1 Shutdown Bank Insertion Limits (LCO 3.2.1.C.3 and 3.2.1.D.1)
The Shutdown Banks shall be fully withdrawn when the reactor is approaching criticality or is critical.
l 2.2 Control Bank Insertion Limits (LCO 3.2.1.C.3 and 3.2.1.D.1)
The Control Bank insertion Limits are specified by Figure 2.2-1.
The sequence for Control Bank withdrawal shall be Control Bank A, Control Bank B, Control Bank C. and Control Bank D.
Successive Control Banks shall overlap by 50 steps.

2.5A Axial Flux Difference (CAOC Methodology)
(LCO 3.2.2.A.2.2.c(2), 3.2.2.A.4, and 3.2.2.A.6.1) 2.5A.1 The AXIAL FLUX DIFFERENCE (AFD) target band is +6%, -7%
of the target flux difference.
2.5 A.2 The AFD acceptable operation limits are an envelope bounded by +y percent and -y percent at a power of 90% of PT and increasing by +1 percent and -1 percent for each 2 percent of rated power below P -
T y = 10.8% of PT rounded to the nearest percent Zion Unit 2 Cycle 13 COLR _
