The BOUARO-MTC shall be less positive or equal to the value given in Figure 1.

The EOUAROIRTP-MTC shall be less negative or equal to -4.lOE-4 Aklkl°F.

This limit is based on a T.TK program with HFP vessel T.VK of 571.0 to 576.0 °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 Page 3 of 19

b. The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative or equal to -3.20E-4 L\k/k/°F at a HFP vessel Tavg 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 L\k/k/°F.

If the Revised Predicted MTC is less negative tl).an the Surveillance Requirement (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 ppm/ARO/RTP-MTC should be less negative or equal to -3.90E-4 Ak/k/°F at a HFP

\

vessel Tavg 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The shutdown rods shall be withdrawn to at least 228 steps.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. The AFD target band is +/-5% for a cycle average accumulated burnup ~0.0 MWD/MTU

d. W(Z) is provided in Table 1 for +/-5% AFD target band.
e. F3' (Z) = Ft (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 perforrped, the W(z) values should be multiplied by the factor 1/P, when Pis> 0.5. When Pis :'.S 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_..
