COLR FOR DONALDC. COOK NUCLEAR PLANT UNIT 2 CYCLE 12 DECEMBER 1997 The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the following subsections. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.9.

2.1 Moderator Tem erature Coefficient (Specification 3/4.1.1.4) 2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

The MTC shall be less positive than or equal to the value given in Figure 1.

The EOL/ARO/RTP-MTC shall be less negative than or equal to - 4.37E-4 LOAM'F.

This limit is based on a Tavg program with HFP vessel Tavg of 571.5'F to 576.5'F where: ARO stands for AllRods Out BOL stands for Beginning of Cycle Life EOL stands for End of Cycle Life RTP stands for Rated Thermal Power HFP stands for Hot Full Thermal Power 2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative than or equal to - 3.57E-4 hk/k/'F at a HFP vessel Tavg of 571.5'F to 576.5'F.

COLR FOR DONALDC. COOK NUCLEAR PLANT UNIT2 CYCLE 12 DECEMBER 1997 2.2 Rod Dro Time Dro Hei ht (Specification 3/4.1.3.4) 2.2.1 Allrods shall be dropped from 225 steps.

2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.3.1 The shutdown rods shall be withdrawn to at least 225 steps.

2.4 Control Rod Insertion Limits (Specifications 3/4.1.3.6 and 3/4.1.3. 1) 2.4.1 The control rod banks shall be limited in physical insertion as shown in Figure 2.

2.4.2 Successive Control Banks shall overlap by 97 steps. The sequence for Control Bank withdrawal shall be Control Bank A, Control Bank B, Control Bank C, and Control Bank D.

2.5 Axial Flux Difference (Specification 3/4.2.1) 2.5.1 The Allowable Operation Limits are provided in Figure 3.

2.5.2 The EGAL FLUX DIFFERENCE (AFD) target band during base load operations is

+3%, -3% (not applicable for this cycle).

2.5.3 The AFD target band is+5%, -5% for a cycle average accumulated burnup > 0.0 MWD/MIU.
