CORE OPERATING LIMITS REPORT, VEGP UNIT 1 CYCLE 21 DECEMBER 2016 1.0 CORE OPERATING LIMITS REPORT This Core Operating Limits Report (COLR) for VEGP Unit 1 Cycle 21 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:
3.1.1 SHUTDOWN MARGIN - MODES 3, 4 and 5 3.1.3 Moderator Temperature Coefficient 3.1.5 Shutdown Bank Insertion Limits 3.1.6 Control Bank Insertion Limits 3.2.1 Heat Flux Hot Channel Factor - FQ(Z) 3.2.2 Nuclear Enthalpy Rise Hot Channnel Factor- FN t.H 3.2.3 Axial Flux Difference 3.9.1 Boron Concentration Page 1 of13
CORE OPERATING LIMITS REPORT, VEGP UNIT 1 CYCLE 21 DECEMBER 2016 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 I and 2 (Technical Requirement 13.1.1) 2.1.1 The SHUTDOWN MARGIN shall be greater than or equal to 1.30 percent ~k/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.

CORE OPERATING LIMITS REPORT, VEGP UNIT I CYCLE 21 DECEMBER 2016 2.3 Moderator Temperature Coefficient (Specification 3.1.3) 2.3.1 The Moderator Temperature Coefficient (MTC) limits are:
The BOLlARO/HZP-MTC shall be less positive than +0. 7 x I 0 4 ~klki°F for power levels up to 70% RTP with a linear ramp to 0 ~k/k/°F at 100% RTP.
The EOLIARO/RTP-MTC shall be less negative than -5.50 x 104 ~k/k/°F.
1 2.3.2 The MTC Surveillance limits are:
The 300 pprn/ARO/RTP-MTC should be less negative than or equal to
-4.75 X 10-4 ~k/k/°F. 1 The revised predicted near-EOL 300 ppm MTC shall be calculated using Figure 6 and the following algorithm:
Revised Predicted MTC Predicted MTC* + AFD Correction** + Predictive Correction***
where,
- Predicted MTC is calculated from Figure 6 at the burnup corresponding to the measurement of300 ppm at RTP conditions,
- AFD Correction is the more negative value of:
{0 pcrn/°F or (~AFD
where: ~AFD is the measured AFD minus the predicted AFD from an incore flux map taken at or near the burnup corresponding to 300 ppm, AFD Sensitivity= 0_08 pcrn/°F I ~AFD
- Predictive Correction is -3 pcrn/°F.
The 60 pprn/ARO/RTP-MTC should be less negative than -5.35 x 104 ~k/k/°F. 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 1
Applicable for full-power T -average of 584.1 to 587 .I °F.

- 1. The Penalty Factor, to be applied to Fo(Z) in accordance with SR 3.2.1.2, is the maximum factor by which Fo(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 Fo(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.
