VOGTLE ELECTRIC GENERATING PLANT (VEGP) UNIT 1 CYCLE 11 CORE OPERATING LIMITS REPORT REVISION 0 MARCH 2002
COLR for VEGP UNIT 1 CYCLE 11 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for VEGP UNIT 1 CYCLE 11 has been prepared in accordance with the requirements of Technical Specification 5.6.5.
The Technical Requirement affected by this report is listed below:
13.1.1 SHUTDOWN MARGIN - MODES 1 and 2 The Technical Specifications affected by this report are listed below:

COLR for VEGP UNIT 1 CYCLE 11 2.0 OPERATING LIMITS The cycle-specific parameter limits for the specifications listed in section 1.0 are presented in the following subsections. These limits have been developed using NRC-approved methodologies, including those specified in Technical Specification 5.6.5.
2.1 SHUTDOWN MARGIN - MODES 1 AND 2 (Technical Requirement 13.1.1) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.30 percent Ak/k.
2.2 SHUTDOWN MARGIN - MODES 3,4 AND 5 (Specification 3.1.1) 2.2.1 The SHUTDOWN MARGIN shall be greater than or equal to the limits shown in Figures 1 and 2.
2.3 Moderator Temperature Coefficient (Specification 3.1.3) 2.3.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOLJARO/HZP - MTC shall be less positive than +0.7 x 10-4 Ak/k/lF for power levels up to 70 percent RTP with a linear ramp to 0 Ak/kPOF at 100 percent RTP.
The EOL/ARO/RTP-MTC shall be less negative than
-5.50 x 104 Ak/k/PF.1 2.3.2 The MTC Surveillance limits are:
The 300 ppm/ARO/RTP-MTC should be less negative than or equal to -4.75 x 104 Ak/k/OF.1 The 60 ppm/ARO/RTP-MTC should be less negative than
-5.35 x 104 Ak/k/0F.1 where:
BOL stands for Beginning of Cycle Life ARO stands for All Rods Out HZP stands for Hot Zero THERMAL POWER EOL stands for End of Cycle Life RTP stands for RATED THERMAL POWER 2.4 Shutdown Bank Insertion Limits (Specification 3.1.5) 2.4.1 The shutdown banks shall be withdrawn to a position greater than or equal to 225 steps.
2.5 Control Bank Insertion Limits (Specification 3.1.6) 2.5.1 The control banks shall be limited in physical insertion as shown in Figure 3.
1Applicable for full-power T-average of 586.40F to 587.40F.

2.9 Boron Concentration (Specification 3.9.1) 2.9.1 The boron concentration shall be greater than or equal to 1970 ppm.1
'This concentration bounds the condition of kef < 0.95 (all rods in less the most reactive rod) and subcriticality (all rods out) over the entire cycle. This concentration includes additional boron to address uncertainties and B13 depletion.

Penalty Factor 1.020 1.030 1.029 1.025 1.022 1.020 Notes:
- 1.
The Penalty Factor, to be applied to Fa(Z) in accordance with SR 3.2.1.2, is the maximum factor by which Fa(Z) is expected to increase over a 39 EFPD interval (surveillance interval of 31 EFPD plus the maximum allowable extension not to exceed 25% of the surveillance interval per SR 3.0.2) starting from the burnup at which the Fa(Z) was determined.
- 2.
Linear interpolation is adequate for intermediate cycle burnups.
- 3.
For all cycle burnups outside the range of the table, a penalty factor of 1.020 shall be used.
