These limits have been developed using the NRC-approved methodologies specified in Technical Specification 5.6.5. 2.1 SHUTDOWN MARGIN lSDMl (Specifications 3.1.1, 3.1.4, 3.1.5, 3.1.6, and 3.1.8) 2.1.1 The Shutdown Margin in MODES 1-4 shall be greater than or equal to 1.3% L\k/k. 2.1.2 The Shutdown Margin prior to blocking Safety Injection below P-11 in MODES 3 and 4 shall be greater than 0% LYc/k as calculated at 200°F. 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 (MTCl (Specification 3.1.3) 2.2.1 The Moderator Temperature Coefficient shall be less positive than the limits shown in Figure I. These limits shall be referred to as upper limit The Moderator Temperature Coefficient shall be less negative than -47.9 pcm/°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This limit shall be referred to as the lower limit 2.2.2 The MTC 300 ppm surveillance limit is -40.4 pcm/°F (all rods withdrawn, Rated Thermal Power condition).
2.2.3 The MTC 60 ppm surveillance limit is -45.5 pcrnfOF {all rods withdrawn, Rated Thennal Power condition).

Revision 1 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 detennining FQ w(z) are shown in Table A. Ia and A.lb.** The W(z) functions shown in Table A.la are only applicable to Figure 4a. The W(z) functions shown in Table A.1 b are only applicable to Figure 4b. The data in these tables should be used independently; cross interpolation or extrapolation between W(z) sets is prohibited.
The Axial Flux Difference (AFD) Band in Figure 4b is more restrictive than the AFD Band in Figure 4a. Prior to switching from Figure 4b to Figure 4a, FQ w(z) must be confirmed to meet Technical Specification requirements by one of the following methods: I. Confinn FQ w(z) meets the Technical Specification Limit with the Table A.la W(z) values for the most recent surveillance perfonned.
- 2. Perfonn a new surveillance and confinn FQw(z) meets the Technical Specification Limit with the Table A. Ia W(z) values. The W(z) values have been detennined for several bumups up to 20000 MWDIMTU in Cycle 20. This pennits detennination of W(z) at any cycle burnup up to 20000 MWD/MTU through the use of three point interpolation.
For cycle bumups greater than 20000 MWDIMTU, use of20000 MWD/MTU W(z) values without extrapolation is conservative.
The W(z) values were determined assuming Cycle 20 operates with RAOC strategy.
The W(z) values are provided for 73 axial points within the core height boundaries ofO and 12.08 feet (hot core height) at equally spaced intervals.
6 Curve Book Figure 13-1, Rev. 056 Callaway Cycle 20 COLR REDESIGN Revision 1 The W(z) values are generated assuming that they will be used for a full power surveillance.
When a part power surveillance is perfonned from beginning of cycle to 150 MWD/MTU and at 45% +!-5% RTP, the W(z) values listed in Table A.2 should be used. When a part power surveillance is perfonned after 150 MWD/MTU, or at a power level other than the level specified above, the HFP W(z) values in Table A.laor A.1b should be used. W(z) values should be adjusted by the factor 1/P, when Pis> 0.5. When 0.5, the W(z) values should be adjusted by the factor 1/(0.5), or 2.0. This is consistent with the adjustment in the Fcf..z) limit at part power conditions.
Table A.3 shows the bumup dependent FQ penalty factors for Cycle 20 which are applicable to both Figures 4a and 4b. These values shall be used to increase FQ w(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 of TableA.3.
- Refer to Table A.2 for W(z) values for evaluating the startup testing flux map at 150 MWDIMTU burnup and 45% +/-5% RTP. 2.5.4 The uncertainty, UFQJ to be applied to measured shall be calculated by the following UFQ= Uqu
