COOK UNIT 2 CYCLE 19 Revision I 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report for the Donald C. Cook Nuclear Plant Unit 2 Cycle 19 has been prepared in accordance with the requirements of Technical Specification 5.6.5.The analytical methods used to determine the core operating limits shall be those previously reviewed and approved by the Nuclear Regulatory Commission (NRC) in: a.

C. COOK UNIT 2 CYCLE 19 Revision 1 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 5.6-5.2.1 SAFETY LIMITS 2.1.1 Reactor Core SLs (Specification 2.1.1)In Modes I and 2, the combination of thermal power, pressurizer pressure, and the highest loop average temperature (Tavg) shall not exceed the limits as shown in Figure 6 for 4 loop operation.
2,2 REACTIVITY CONTROL 2.2.1 SHUTDOWN MARGIN (SDM) (Specification 3.1.1)Shutdown margin shall be greater than or equal to 1.8% Ak/k for Tavg > 200'F Shutdown margin shall be greater than or equal to 1.0% Ak/k for Tavg < 200'F 2.2.2 Moderator Temperature Coefficient (MTC) (Specification 3.1.3)a. The MTC limits are: The BOL/ARO-MTC shall be less positive or equal to the value given in Figure 1.The EOL/ARO/RTP-MTC shall be less negative or equal to -4.1 OE-4 Ak/kF.This limit is based on a Ta.g program with HFP vessel Tavg of 571.0 to 576.0 OF 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 Page 3 of 16 D. C. COOK UNIT 2 CYCLE 19 Revision I b. The MTC Surveillance limit is: The 300 ppm/ARO/RTP-MTC should be less negative or equal to -3.20E-4 Awk/&deg;F at a HFP vessel Tavg of 571:0 to 576.0 OF c. The Revised Predicted near-EOL 300 ppm MTC shall be calculated using Figure 7 and the following algorithm:
Revised Predicted MTC = Predicted MTC + AFD Correction
+ Predicted Correction*
* Predicted Correction is -0.30E-4 A/k/kF.If the. Revised Predicted MTC is less negative than the Surveillance Requirement 3.1.3.2 limit (COLR 2.2.2.b) and all of the benchmark data contained in the surveillance procedure are met, then a MTC measurement in accordance with SR 3.1.3.2 is not required.d. The MTC Surveillance limit is: The 60 ppm/ARO/RTP-MTC should be less negative or equal to -3.90E-4 Ak/k/&deg;F at a HFP vessel Tavg of 571.0 to 576.0 OF 2.2.3 Shutdown Bank Insertion Limits (Specification 3.1.5)The shutdown rods shall be withdrawn to at least 228 steps.2.2.4 Control Bank Insertion Limits (Specifications 3.1.6)a. The control rod banks shall be limited in physical insertion as shown in Figure 2.b. 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.2.3 POWER DISTRIBUTION LIMITS 2.3.1 AXIAL FLUX DIFFERENCE (AFD) (Specification 3.2.3)a.

: d. W(Z) is provided in Table 1 for +5% AFD target band.e. FQ (Z) = FQ (Z) x W(Z) x F, The W(z) values are generated assuming that they will be used for a full power surveillance.
When a part power surveillance is performed, the W(z) values should be multiplied by the factor 1/P, when P is > 0.5. When P is < 0.5, the W(z) values should be multiplied by the factor 1/(0.5), or 2.0. This is consistent with the adjustment in the FQ(z) limit at part power conditions.
