D. C. COOK UNIT I CYCLE 20 REVISION 0 April 2005 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for Donald C. Cook Nuclear Plant Unit I Cycle 20 design has been prepared in accordance with the requirements of Technical Specification 6.9.1.9.

The Technical Specifications affected by this report are listed below:

3/4.1.1.4 Moderator Temperature Coefficient 3/4.1.3.1 Movable Control Assemblies Group Height 3/4.1.3.3 Rod Drop Time 3/4.1.3.4 Shutdown Rod Insertion Limit 3/4.1.3.5 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference (AFD) 3/4.2.2 Heat Flux Hot Channel Factor (FQ(Z))

3/4.2.3 Nuclear Enthalpy Hot Channel Factor (FNm) 3/4.2.6 Allowable Power Level (APL) 1 of9

D. C. COOK UNIT I CYCLE 20 REVISION 0 April 2005 2.0 OPERATING LIMITS 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 Specifications 6.9.1.9.

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

The BOL/ARO-MTC shall be less positive than the value given in Figure 1.

The EOL/ARO/RTP-MTC shall be less negative than -4.54 x10 4 Ak/kc/ 0F.

This limit is based on a T,,g program with HFP Tavg of 554.0 - 558.0 'F.

Where: ARO stands for All Rods 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

-3.84 xI04Akfk/kF at a vessel average temperature of 554.0 - 558.0 'F.

2.2 Rod Drop Time Drop Height (Specification 3/4.1.3.3) 2.2.1 All rods shall be dropped from 228 steps.

2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 228 steps.

D. C. COOK UNIT 1 CYCLE 20 REVISION 0 April 2005 2.4 Control Rod Insertion Limits (Specifications 3/4.1.3.5 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 100 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 (AED) (Specification 3/4.2.1) 2.5.1 The Allowable Operation Limits are provided in Figure 3.

2.5.2 The 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 bumup 20.0 MWD/MTU.

2.6 Heat Flux Hot Channel Factor - FQ(Z) (Specification 3.2.2)
