The Technical Specifications affected by this report are listed below:

3/4.1.1.4 Moderator Temperature Coefficient (MTC) 3/4.1.3.1 Movable Control Assemblies Group Height 3/4.1.3.4 Rod Drop Time 3/4.1.3.5 Shutdown Rod Insertion Limit 3/4.1.3.6 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 - (Fan) 3/4.2.6 Allowable Power Level (APL) 1 of 9

D. C. COOK UNIT 2 CYCLE 15 OCTOBER 2004 2.0 OPERATING LIMITS The cycle-specific parameter limits 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 6.9.1.9.

2.1 Moderator Temperature Coefficient (Technical 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 or equal to the value given in Figure 1.

The EOL/ARO/RTP-MTC shall be less negative than or equal to -4.1 OE-4 Ak/WF.

This limit is based on a Ta.g program with HFP vessel Tag of 571 to 576 '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 or equal to -3.20E-4 Ak/k/0F at a HFP vessel Tag of 571 to 576 'F 2.2 Rod Drop Time Drop Height (Specification 3/4.1.3.4) 2.2.1 All rods shall be dropped from 228 steps.

2.3 Shutdown Rod Insertion Limit (Specification 3/4.1.3.5) 2.3.1 The shutdown rods shall be withdrawn to at least 228 steps.
