D. C. COOK UNIT 2 CYCLE 18 Revision 0 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 Safety Limits (Specification 2.1.1)
In Modes 1 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 1.3% Ak/k for Tavg > 200OF Shutdown margin shall be greater than or equal to 1.0% Ak/k for Tavg -< 200OF 2.2.2 Moderator Temperature Coefficient (MTC) (Specification 3.1.3)
- a.
The Moderator Temperature Coefficient (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 -4.1OE-4 Ak/k/°F.
This limit is based on a Tavg 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 18 Revision 0
- b.
The MTC Surveillance limit is:
The 300 ppm/ARO/RTP-MTC should be less negative or equal to -3.20E-4 Ak/k/°F at a HFP vessel Tag of 571.0 to 576.0 'F
- 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 Ak/k/°F.
If the Revised Predicted MTC is less negative than the SR 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 ppmi/ARO/RTP-MTC should be less negative or equal to -3.90E-4 Ak/k/IF at a HFP vessel Tvg of 571.0 to 576.0 'F 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The shutdown rods shall be withdrawn to at least 228 steps.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.
The Allowable Operation Limits are provided in Figure 3.
- b.

- b. K(Z) is provided in Figure 4.

FQ(Z) is the measured hot channel factor including a 3% manufacturing tolerance uncertainty and a 5% measurement uncertainty.
- d. W(Z) is provided in Table 1 for +5% AFD target band.
- e.
FQ (Z) = c (Z) x W(Z) x Fp 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 l/P, when P is > 0.5. When P is:< 0.5, the W(z) values should be multiplied by the factor 11(0.5), or 2.0. This is consistent with the adjustment in the FQ(z) limit at part power conditions.
