DONALD C. COOK NCULEAR PLANT UNIT 1 CYCLE 11 CORE OPERATING LIMITS REPORT Revision 0 September', 1990

COLR for DONALD C. COOK NUCLEAR PLANT UNIT 1 CYCLE ll 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report for Donald C. Cook Nuclear Plant Unit 1 Cycle 11 has been prepared in accordance with the requirements of Technical Specification 6.9.1.11.

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 Limits 3/4.1.3.5 Control Rod Insertion Limits 3/4.2.1 Axial Flux Difference 3/4.2.2 Heat Flux Hot Channel Factor 3/4.2.3 Nuclear Enthalpy Hot Channel Factor 3/4.2.6 Allowable Power Level Page 1 of 11

COLR for Donald C: Cook Nuclear Plant Unit 1 Cycle 11 2.0 OPERATING LIMITS The cyle-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' 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/RTP-MTC shall be less negative than

-3.35E-4 6k/k/ F.

This limit is based on a T avg program with HFP T

avg of 550 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 -2.75E-4 hk/k/'F at a vessel average temperature of 550 F.

2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 228 steps.

2.4 Control Rod Insertion Limits (Specification 3/4.1.3.5, and 3/4.1.3.1) 2.4.1 The control 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 (Specification 3/4.2.1) 2.5.1 The Allowable Operation Limits are provided in Figure 3.

l 2.5.2 The AXIAL 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 core average accumulated burnup > 0.0 MUD/MTU Page 3 of 11
