Callaway Cycle 6 Rev.0 2.0 OPER ATING 1.lMITS ne cycle specific parameter limits for the specifications listea in & : tion 1.0 are presented in the subsections which follow. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.9.
2.1 Moderator Trmnerature Coefficient (Specification 3.1.1.3) 2.1.1 The Moderator Temperature Coefficient shall be less positive than the limits shown iri Figur .1. These limits shall be referred to as the Beginning of Cycle Life (DOL) Limit.
The Moderator Temperature Coefficient shall be less negative than .41 pcmrF.
This limit shall be referred to as the End of Cycle Life (EOL) Limit.
2.1.2 The MTC 300 ppm surveillance limit is 32 pcmfF (all rods withdrawn. Rated Thermal Power condition).

RATED THERMAL POWER 2.5.1 FoRR = 2.50 2.5.2 K(Z) is provided in Figure 4.
2.5.3- The W(z) functions that are to be used in Technical Specifications 4.2.2.2,4.2.2.3, and 4.2.2.4 for Fosurveillance are shown in Figures 5 through 7.
Because significant margin exists between the analytically detennined maximum Fo(z)*Pg values and their limit, Restricted Axial Flux Difference (RAFDO) operation is not expected to be required for Cycle 6. For this reason, no W(z)aAmo values are supplied for Cycle 6.
The Normal Operation W(z) values, W(z),o, have Seen determined for three specific burnups in Cycle 6. This permits determination of W(z) at any cycle burnup up to 6000 MWD /MTU through the use of three point interpolation. The W(z),o values were determined assuming Cycle 6 operates with the CAOC strategy and uses a +10%, .9% Al band about the target flux difference.
The W(z) values are provided for 73 axial points assuming the core height boundaries of 0 and 12 feet and intervals of.167 feet between the core boundaries.
