COOK NUCLEAR PLANT UNIT 1 CYCLE 13 1+0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report for Donald C. Cook Nuclear Plant Unit 1 Cycle 13 has been prepared in accordance with the recpxlrements of Technical Specification 6.9.1.11.

The Technical Specifications affected by this report are listed below:

3/4.1.1.4 3/4.1.3.1 3/4.1.3.3 3/4.1.3.4 3/4.1.3.5 3/4.2.1 3/4.2.2 3/4.2.3 3/4.2.6 Moderator Temperature Coefficient Movable Control Assemblies Group Height Rod Drop Time Shutdown Rod Insertion Limits Control Rod Insertion Limits Axial Flux Difference Heat Flux Hot Channel Factor Nuclear Enthalpy Hot Channel Factor Allowable Power Level Page 1 of 11

OPERATINO 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 Specification 6.9.1.11.

2.1 Moderator Tem erature 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/RTg-MTC shall be less negative than

-4.59E-4 hk/k/ F.

Thi8 limit is based on a T program with HFP T of 553 F

avg avg where:

ARO stands BOL stands EOL stands RTP stands HFP stands for All Rods Out for Beginning of Cycle Life for End of Cycle Life for Rated Thermal Power for Hot Full Thermal Power 2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTCoshould be less negative than or equal to -3.67E-4 6k/k/ F at a vessel average temperature of 553 F.

COLR for Donald C. Cook Nuclear Plant Unit 1 Cycle 13 2.2 Rod Dro Time Dro Hei ht (Specification 3/4.1.3.3) 2.2.1 All rods shall be dropped from 231 steps.

2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 231 steps.

2.4 Control Rod Insertion Limits (Specifications 3/4.1.3.5 and 3/4.1.3.1) 2.4.1 2.4.2 The control rod banks shall be limited in physical insertion as shown in Figure 2.

Successive Control Banks shall overlap by 103 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 2.5.2 2.5.3 The Allowable Operation Limits are provided in Figure 3.

The AXIAL FLUX DIFFERENCE (AFD) target band during base load operations is +3%,

-3% (not applicable for this cycle).

The AFD target band is +5%,

-5% for a cycle average accumulated burnup > 0.0 MWD/MTU.
