COLR for DONALDC. COOK NUCLEARPLANTUNIT I CYCLE 16 - APRIL 1997 1.0 CORE OPERATING LIMITSREPORT This Core Operating Limits Report for the Donald C. Cook Nt.clear Plant Unit I Cycle 16 redesign has been prepared in accordance with the requirements ofTechnical 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 Ilot Channel Factor Nuclear Enthalpy Hot Channel Factor Allowable Power Level Page I of 11 Revision 0
COLR for DONALDC. COOK NUCLEARPLANTUNIT 1 CYCLE 16-APRIL 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 6.9.1.11.
2.1 Moderator Tern 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 l.
The EOL/ARO/RTP-MTC shall be less negative than -4.54F:4 hk/k/'F.
Tile EOL/ARO/RTP MTC liinit is based on a Tavg prograin witli IIFP Tavg of 553 F (Note 1) where:
ARO stands for AllRods Out BOL stands for Beginning ofCycle Life EOL stands for End ofCycle Life RTP stands for Rated Thermal Power HFP stands for Hot Full Thermal Power 2.1.2 The MTC Surveillance limitis:
The 300 ppm/ARO/RTP-MTC should be less negative than or equal to - 3.84E-4 hk/k/'F at a vessel average temperature of553'F. (Note 1)
Note I -Unit 1 Cycle 16 willbe run with a Tavg of556'F Revision I oftile COLR willrevise tile EOL/ARO/RTP-MTC and the 300 ppm/ARO/RTP-MTC limits to reflect the 556'F Tavg by May 15, 1997. This new value was not available at the time of issuance of Revision 0 because ofthe late decision to change Tavg due to the as found steam generator condition.

2.3 Shutdown Rod Insertion Limit(Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 225 steps.
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 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 AXIALFLUXDIFFERENCE (AFD) target bai:d 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/MTU.
