- 7. 3.2.1 Heat Flux Hot Channel Factor (FQ@
The Heat Flux Hot Channel Factor shall be within the following limits:
CFQ=2.50 K(Z) is a constant value= 1.0 at all elevations.
The HFP W(Z) values are provided in Table 2 and Table 4.
The W(Z) values in Table 2 and Table 4 are applicable to Figure 5.
The data in Tables 2 and 4 should be used independently; cross interpolation or extrapolation between W(Z) sets is prohibited.
The Part Power W(Z) values for 75% .'.SP < 85% and Part Power W(Z) values for 85 .'.SP < 95% are provided in Table 6.
The W(Z) values in Table 6 are applicable to Figure 5.
The FwQ(Z) Penalty Factors associated with Figure 5 and Table 2 are provided in Table 3.
The FwQ(Z) Penalty Factors associated with Figure 5 and Table 4 are provided in Table 5.
The W(Z) values in Table 4 are based on a steady-state model with perturbed Axial Flux Difference (AFD) that simulates a Delta-Axial-Offset (D-AO) of -4%
for the entire cycle. D-AO is defined as the measured Axial Offset (AO) less the predicted AO from Table 2. The ranges of applicability for the Table 2 and 4 W(z) values are defined below:
- 1. Table 2 values should be used when D-AO is in the range of +/-3%
of the Table 2 supplied AO.
- 2. Table 4 values should be used when D-AO is more negative than
-3% and more positive than -7% of the Table 2 supplied AO.
Page 4 of26
Core Operating Limits Report Unit 2, Cyc;le 31 Revision 0 The HFP W(Z) values are generated assuming that they will be used for full power surveillance. Part power W(Z) values are only required to be used when the part power surveillance is performed using the moveable incore detector system.
When a part power surveillance is performed from BOC through 150 MWd/MTU and at a power level specified for Table 6, the W(Z) values provided in Table 6 should be used. When a part power surveillance is performed after 150 MWD/MIU, or at a power level other than those specified for Table 6, the HFP W(Z) values in Table 2 or Table 4 should be used.
W(Z) values should be multiplied by the factor 1/P, when P > 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 conditions.

- For Mode 1 and Mode 2 with Keff;::: 1.0, the minimum shutdown margin requirements are provided by the Rod Insertion Limits.
- Charging pump(s) in service only pertains to steady state operations. It does not include transitory operations. For example, operations such as starting a second charging pump in order to secure the operating pump would fall under the one pump in service column.
Note: Linear interpolation between burnup steps is allowed. Extrapolation is not allowed.
