2.1.3 The Shutdown Margin in MODE 5 shall be greater than or equal to 1.0% Ak/k.
2.2 Moderator Temperature Coefficient (MTC)(Specification 3.1.3)
2.2.1 The Moderator Temperature Coefficient shall be less positive than the limits shownin Figure 1 . These limits shall be referred to as the upper limit. Figure 1 cannot berevised under 10 CFR 50.59 due to Technical Specification Figure 3.1.3-1.
The Moderator Temperature Coefficient shall be less negative than -47.9 pcml°F.This limit shall be referred to as the lower limit.
2.2.2 The MTC 300 ppm surveillance limit is -40.4 pcm/°F (all rods withdrawn, RatedThermal Power condition).
2.2.3 The MTC 60 ppm surveillance limit is -45.5 pcml°F (all rods withdrawn, RatedThermal Power condition).

2.3 Shutdown Bank Insertion Limits(Specification 3.1.5)
The shutdown banks shall be withdrawn to at least 222 steps.
2.4 Control Bank Insertion Limits(Specification 3.1.6)
2.4.1 Control Bank insertion limits are specified by Figure 2.
2.4.2 Control Bank withdrawal sequence is A-B-C-D. The insertion sequence is thereverse ofthe withdrawal sequence.
2.4.3 The difference between each sequential Control Bank position is 1 1 5 steps whennot fully inserted and not fully withdrawn. Overlap is defined as the fhllywithdrawn (ARO) position minus this 1 15 step tip-to-tip separation.

2.5.1 FQ{T)= 2.50.
2.5.2 K(Z) is provided in Figure 3.
2.5.3 The W(z) functions that are to be used in Technical Specification 3.2.1 and
Surveillance Requirement 3 .2.1 .2 for determining FQW(z) are shown in Table A. laand A.lb.** The W(z) functions shown in Table A.la are only applicable toFigure 4a. The W(z) functions shown in Table A.lb are ànly applicable toFigure 4b. The data in these tables should be used independently; crossinterpolation or extrapolation between W(z) sets is prohibited.
The Axial Flux Difference (AFD) Band in Figure 4b is more restrictive than theAFD Band in Figure 4a. Prior to switching from Figure 4b to Figure 4a, FQW(Z)
must be confirmed to meet Technical Specification requirements by one of thefollowing methods:
1 . Confirm FQW(z) meets the Technical Specification Limit with theTable A. 1 a W(z) values for the most recent surveillance performed.
.2. Perform a new surveillance and confirm FQW(z) meets the Technical
Specification Limit with the Table A.la W(z) values.
The W(z) values have been determined for several burnups up to18000 MWD/MTU in Cycle 24. This permits determination of W(z) at any cycleburnup up to 18000 MWD/MTU through the use of three point interpolation. Forcycle burnups greater than 1 8000 MWD/MTU, use of 1 8000 MWD/MTU W(z)values without extrapolation is conservative. The W(z) values were determinedassuming Cycle 24 operates with RAOC strategy.
The W(z) values are provided for 73 axial points within the core height boundariesof 0 and 1 2.07 feet (hot core height) at equally spaced intervals.

Callaway Cycle 24 REDESIGN COLR — Revision 1
The W(z) values are generated assuming that they will be used for a full powersurveillance. When a part power surveillance is performed from beginning ofcycle to 150 MWD/MTU and at 45% +1- 5% RTP, the W(z) values listed in TableA.2 should be used. When a part power surveillance is performed after150 MWD/MTU, or at a power level other than the level specified above, the HFPW(z) values in Table Ala or A.lb should be used.
W(z) values should be adjusted by the factor liP, when P is > 0.5. When P is0.5, the W(z) values should be adjusted by the factor 1/(O.5), or 2.0. This isconsistent with the adjustment in the FQ(z) limit at part power conditions.
Table A.3 shows the burnup dependent FQ penalty factors for Cycle 24 that areapplicable to both Figures 4a and 4b. These values shall be used to increase FQW(z)when required by Technical Specification Surveillance Requirement 3 .2.1 .2. A 2%penalty factor should be used at all cycle burnups that are outside the range ofTable A.3.
** Refer to Table A.2 for W(z) values for evaluating the startup testing flux mapat 1 50 MWD/MTU burnup and 45% +7- 5% RTP.
2.5.4 The uncertainty, UFQ, to be applied to measured FQ(Z) shall be calculated by thefollowing
UFQ Uqu Ue
where:Uqu Base FQ measurement uncertainty 1 .05 when PDMS is inoperable
(Uqu 5 defined by PDMS when OPERABLE)Ue Engineering uncertainty factor = 1.03
