V. C. Summer Cycle 17 November 2006 1.0 Core Operating Limits Report This Core Operating Limits Report (COLR) for V. C. Summer Station Cycle 17 has been prepared in accordance with the requirements of Technical Specification 6.9..1.1.

The Technical Specifications affected by this report are listed below:

3.1.1.3 Moderator Temperature Coefficient 3.1.3.5 Shutdown Rod Insertion Limits 3.1.3.6 Control Rod Insertion Limits 3.2.1 Axial Flux Difference 3.2.2 Heat Flux Hot Channel Factor 3.2.3 RCS Flow Rate and Nuclear Enthalpy Rise Hot Channel Factor 3.3.3.11 Power Distribution Measurement Uncertainty Revision 0

V. C. Summer Cycle 17 November 2006 2.0 Operating Limits The cycle-specific parameter limits for the specifications listed in Section 1.0 are presented in the subsections which follow. These limits have been developed using the NRC-approved methodologies specified in Technical Specification 6.9.1.11.

2.1 Moderator Temperature Coefficient (Specification 3.1.1.3):

2.1.1 The Moderator Temperature Coefficient (MTC) limits are:

The BOL/ARO-MTC shall be less positive than the limits shown in Figure 1.

The EOL/ARO/RTP-MTC shall be less negative than -5x10-4 Ak/k/0F.

where:

BOL stands for Beginning of Cycle Life ARO stands for All Rods Out RTP stands for RATED THERMAL POWER EOL stands for End of Cycle Life 2.1.2 The MTC Surveillance limit is:

The 300 ppm/ARO/RTP-MTC should be less negative than or equal to -4.1 x 10-4 Ak/k/ 0F 2.1.3 The Revised Predicted near-EOL 300 ppm MTC shall be calculated using the following algorithm from Reference 2:

Revised Predicted MTC = Predicted MTC + AFD Correction*+ Predictive Correction**

  • AFD Correction is 0.05 pcm/°F/%AAFD.
    • Predictive Correction is -3 pcm/°F.

If the Revised Predicted MTC is less negative than the SR 4.1.1.3b limit of

-4. 1x 10 4 Ak/k/°F, and all of the benchmark data contained in the surveillance procedure are met, then an MTC measurement in accordance with SR 4.1.1.3b is not required.

2.2 Shutdown Rod Insertion Limits (Specification 3.1.3.5):

The shutdown rods shall be withdrawn to at least 230 steps.

2.3 Control Rod Insertion Limits (Specification 3.1.3.6):

Control Bank A and B rods shall be withdrawn to at least 230 steps. Control Bank C and D Insertion Limits are specified by Figure 2. Control rod overlap is 102 steps.

2 Revision 0

V. C. Summer Cycle 17 November 2006 2.4 Axial Flux Difference (Specification 3.2.1):

2.4.1 The Axial Flux Difference (AFD) Limits for RAOC operation for Cyclel7 are shown in Figure 3.

2.4.2 The Axial Flux Difference (AFD) target band during base load operations for Cycle17 is:

BOL - EOL (0 - 23,800 MWD/MTU): +/-5% about a measured target value.

2.4.3 The minimum allowable power level for base load operation, APLND, is 75% of RATED THERMAL POWER.

2.5 Heat Flux Hot Channel Factor - FQ(z) (Specification 3.2.2):

F RTP FQ (Z)

M-x K(Z) for P > 0.5 P

FQ (Z) < FQTP x K(Z) for P _ 0.5 where: P Thermal Power 0.5 Rated Thermal Power 2.5.1 FRTP =2.40 2.5.2 K(z) is provided in Figure 4.

2.5.3 Elevation dependent W(z) values for RAOC operation at 150, 3000, 10000, and 20000 MWD/MTU are shown in Tables 1 through 4, respectively. This information is sufficient to determine W(z) versus core height in the range of 0 MWD/MTU to EOL burnup through the use of three point interpolation. Table 5 shows FQ margin decreases for RAOC operation that are greater than 2% per 31 Effective Full Power Days (EFPD).

These values shall be used to increase FQM(z) as per Surveillance Requirement 4.2.2.2e.

A 2% penalty factor shall be used at all burnups that are outside the range of Table 5.

2.5.4 Elevation dependent W(Z)BL values for Baseload operation between 75 and 100% of rated thermal power with the item 2.4.2 specified target band about a measured target value at 150, 3000, 10000, and 20000 MWD/MTU are shown in Tables 6 through 9, respectively.

This information is sufficient to determine W(Z)BL versus core height for burnups in the range of 0 MWD/MTU to EOL burnup through the use of three point interpolation.

Table 10 shows FQ margin decreases for base load operation that are greater than 2% per 31 Effective Full Power Days (EFPD). These values shall be used to increase FQM(z) as 3

V. C. Summer Cycle 17 November 2006 per Surveillance Requirement 4.2.2.4e. A 2% penalty factor shall be used at all burnups that are outside the range of Table 10.

2.7 Power Distribution Measurement Uncertainty (Specifications 3.2.2 and 3.2.3):

If the Power Distribution Monitoring System is OPERABLE, as defined in Technical Specification 3.3.3.11, the uncertainty, UFAH, to be applied to the Nuclear Enthalpy Rise Hot Channel Factor FN A shall be calculated by the following formula:

U~x U
