R. E. Ginna Nuclear Power Plant COLR-3 Revision 0 COLR Cycle 45
BOL stands for Beginning of Cycle Life
EOL stands for End of Cycle Life
HZP stands for Hot Zero Power
RTP stands for RATED THERMAL POWER

2.5 Control Bank Insertion Limits1
2.5.1 The control banks shall be limited in physical insertion as shown in Figure COLR-
- 3. Control Bank A shall be at least 220 steps withdrawn.
2.5.2 The control rod banks shall be withdrawn maintaining a nominal 130 step tip-to-tip d is t ance while moving i n overlap through the active core region.
2.6 Heat Flux Hot Channel Factor (FQ(Z))2
2.6.1 FQ(Z) CFQ
- K(Z) I P for P > 0.5
FQ(Z) CFQ
- K(Z) I 0.5 for P 0.5

2.6.3 K(Z) is provided in Figure COLR-4
2.6.4 W(Z) values are provided in Table COLR-1. For W(Z) data at a desired burnup not listed in the table, but less than the maximum listed b u r n u p, values at 3 or more burnup steps should be used to interpolate the W(Z) data to the desired burnup with a polynomial type fit that us es the W(Z) data for the nearest three burnup steps.
R. E. Ginna Nuclear Power Plant COLR-4 Revision 0 COLR Cycle 45
For W(Z) data at a desired burnup outside of the listed burnup steps, a linear extrapolation of the W(Z) data for the nearest two burnup steps can be used.
If data are listed for only two burnup steps, a linear fit can be used for both interpolation and extrapolation.
2.6.5 The FQ(Z) penalty factors are provided in Table COLR-2.
2.6.6 Table COLR-3 provides W(Z) values for the BOC startup flux map to be taken prior to exceeding 50% th en 75% power. For part power surveillances during other times in life or at powers other than those listed in Table COLR-3, the W(Z) values in Table COLR-1 should be used. The W(Z) values in Table COLR-3 do not include the 1/P factor, where P is the surveillance power level.
This factor will be applied by the BEACON TM Core Monitoring System.
2.6.7 Table COLR-4 contains the required operating space reduction values for THERMAL POWER and AXIAL FLUX DIFFERENCE (AFD) when FQW(Z) is not within its limits. These values are used in conjunction with Technical Specification LCO 3.2.1 Requ ired Actions B.1 and B.2.

2.8 AXIAL FLUX DIFFERENCE (AFD)3
2.8.1 The AFD acceptable operation limits are provided in Figure COLR-5. These limits may be modified in accordance with Table COLR-4 if Technical Specification LCO 3.2.1 Required Ac tions B.1 and B.2 must be taken.
