Revision 1

December 1997

COLR FOR DONALDC. COOK NUCLEARPLANTUNIT2 CYCLE 12 DECEMBER 1997 1.0 CORE OPERAT1NG LIMITSREPORT This Core Operating LimitsReport for the Donald C. Cook Nuclear Plant Unit 2 Cycle 12 has been prepared in accordance with the requirements ofTechnical Specification 6.9.1.9.

The Technical Specifications affected by this report are listed below:

COLR FOR DONALDC. COOK NUCLEARPLANTUNIT2 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 MTCshall 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 limitis based on a Tavg program withHFP vessel Tavg of571.5'F to 576.5'F where: ARO stands forAllRods Out BOL stands for Beginning ofCycle Life EOL stands for End ofCycle Life RTP stands for Rated Thermal Power HFP stands forHot Full Thermal Power 2.1.2 The MTC Surveillance limitis:

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 of571.5'F to 576.5'F.

COLR FOR DONALDC. COOK NUCLEARPLANTUNIT2 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2.3 Shutdown Rod Insertion Limit(Specification 3/4.1.3.5) 2.3.1 The shutdown rods shall be withdrawn to at least 225 steps.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 AxialFlux Difference (Specification 3/4.2.1) 2.5.1 The Allowable Operation Limits are provided in Figure 3.

2.5.2 The EGALFLUXDIFFERENCE (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.
