D. C. COOK UNIT CYCLE 19 November 2003 D. C. COOK UNIT 1 CYCLE 19 November 2003 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/AROJRTP-MTC shall be less negative than -4.54 xI04 Ak/k/0F.

This limit is based on a Tavg program with HFP Ta.g of 554.0 - 558.0 IF.

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 x104AW/U/°F 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2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.4) 2.3.1 The shutdown rods shall be withdrawn to 228 steps.

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 (AFD) (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 burnup 20.0 MWDIMTU.
