1.0 INTRODUCTION
This CORE OPERATING LIMITS REPORT (COLR) describes the cycle-specific parameter limits for operation of St. Lucie Unit 2. It contains the limits for the following as provided in Section 2.
Moderator Temperature Coefficient, CEA Position - Misalignment > 15 Inches, Regulating CEA Insertion Limits, Linear Heat Rate, TOTAL INTEGRATED RADIAL PEAKING FACTOR - FT DNB Parameters, Refueling Operations - Boron Concentration, SHUTDOWN MARGIN - Tavg Greater Than 200 °F, SHUTDOWN MARGIN - Tavg Less Than or Equal To 200 OF.
This report also contains the necessary figures which give the limits for the above listed parameters.
Terms appearing in capitalized type are DEFINED TERMS as defined in Section 1.0 of the Technical Specifications.
This report is prepared in accordance with the requirements of Technical Specification 6.9.1.11.

L-201 5-265 Attachment Page 4 of 18 2.0 CORE OPERATING LIMITS 2.1 Moderator Temperature Coefficient (TS 3.1.1.4)
The moderator temperature coefficient (MTC) shall be less negative than -32 pcm/PF at RATED THERMAL POWER.
2.2 CEA Position - Misaliqnment > 15 Inches (TS 3.1.3.1)
The time constraints for full power operation with one full-length CEA misaligned from any other CEA in its group by more than 15 inches are shown in Figure 3.1-1a.
2.3 Regulatingq CEA Insertion Limits (TS 3.1.3.6)
The regulating CEA groups shall be limited to the withdrawal sequence and to the insertion limits shown on Figure 3.1-2, with CEA insertion between the Long Term Steady State Insertion Limits and the Power Dependent Insertion Limits restricted to:
- a. _<4 hours per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> interval,
- b. _<5 Effective Full Power Days per 30 Effective Full Power Days, and
- c. _<14 Effective Full Power Days per calendar year.
2.4 Linear Heat Rate (TS 3.2.1)
The linear heat rate shall not exceed the limits shown on Figure 3.2-1.
The AXIAL SHAPE INDEX power dependent control limits are shown on Figure 3.2-2.
Excore Detector Monitoringq System During operation, with the linear heat rate (LHR) being monitored by the Excore Detector Monitoring System, the AXIAL SHAPE INDEX shall be maintained within the limits of Figure 3.2-2.
Cycle specific W(z) curves to be used inthe linear heat rate verification, to account for power distribution transients, are shown in Table 3.2-3 as function of core height for various cycle burnups. For other cycle burnups, W(z) values may be interpolated or extrapolated as needed.
If the margin to the linear heat rate has decreased as determined from the last two flux maps, then the linear heat rate must be increased by an appropriate penalty. A value of 2% is chosen as the standard penalty. Linear heat rate margin decreases that are predicted to be greater than 2% per 31 Effective Full Power Days require that penalty factors of greater than 2%Y be used to increase the measured linear heat rate LHRM(z). The incremental penalty factors (in excess of 2%* margin decrease) are included in the W(z) function of Table 3.2-3.

2.5 TOTAL INTEGRATED RADIAL PEAKING FACTOR - FT (TS 3.2.3)
The calculated value of FrT shall be limited to _<1.60.
The power dependent FK limits are shown on Figure 3.2-3.
The following DNB-related parameters shall be maintained within the limits shown on Table 3.2-2:
- a. Cold Leg Temperature
- b. Pressurizer Pressure
With the reactor vessel head closure bolts less than fully tensioned or with the head removed, the boron concentration of all filled portions of the Reactor Coolant System and the refueling canal shall be maintained uniform and sufficient to ensure that the more restrictive of the following reactivity conditions is met:

1.0 INTRODUCTION
This CORE OPERATING LIMITS REPORT (COLR) describes the cycle-specific parameter limits for operation of St. Lucie Unit 2. It contains the limits for the following as provided in Section 2.
Moderator Temperature Coefficient, CEA Position - Misalignment > 15 Inches, Regulating CEA Insertion Limits, Linear Heat Rate, TOTAL INTEGRATED RADIAL PEAKING FACTOR - FT DNB Parameters, Refueling Operations - Boron Concentration, SHUTDOWN MARGIN - Tavg Greater Than 200 °F, SHUTDOWN MARGIN - Tavg Less Than or Equal To 200 OF.
This report also contains the necessary figures which give the limits for the above listed parameters.
Terms appearing in capitalized type are DEFINED TERMS as defined in Section 1.0 of the Technical Specifications.
This report is prepared in accordance with the requirements of Technical Specification 6.9.1.11.

L-201 5-265 Attachment Page 4 of 18 2.0 CORE OPERATING LIMITS 2.1 Moderator Temperature Coefficient (TS 3.1.1.4)
The moderator temperature coefficient (MTC) shall be less negative than -32 pcm/PF at RATED THERMAL POWER.
2.2 CEA Position - Misaliqnment > 15 Inches (TS 3.1.3.1)
The time constraints for full power operation with one full-length CEA misaligned from any other CEA in its group by more than 15 inches are shown in Figure 3.1-1a.
2.3 Regulatingq CEA Insertion Limits (TS 3.1.3.6)
The regulating CEA groups shall be limited to the withdrawal sequence and to the insertion limits shown on Figure 3.1-2, with CEA insertion between the Long Term Steady State Insertion Limits and the Power Dependent Insertion Limits restricted to:
- a. _<4 hours per 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> interval,
- b. _<5 Effective Full Power Days per 30 Effective Full Power Days, and
- c. _<14 Effective Full Power Days per calendar year.
2.4 Linear Heat Rate (TS 3.2.1)
The linear heat rate shall not exceed the limits shown on Figure 3.2-1.
The AXIAL SHAPE INDEX power dependent control limits are shown on Figure 3.2-2.
Excore Detector Monitoringq System During operation, with the linear heat rate (LHR) being monitored by the Excore Detector Monitoring System, the AXIAL SHAPE INDEX shall be maintained within the limits of Figure 3.2-2.
Cycle specific W(z) curves to be used inthe linear heat rate verification, to account for power distribution transients, are shown in Table 3.2-3 as function of core height for various cycle burnups. For other cycle burnups, W(z) values may be interpolated or extrapolated as needed.
If the margin to the linear heat rate has decreased as determined from the last two flux maps, then the linear heat rate must be increased by an appropriate penalty. A value of 2% is chosen as the standard penalty. Linear heat rate margin decreases that are predicted to be greater than 2% per 31 Effective Full Power Days require that penalty factors of greater than 2%Y be used to increase the measured linear heat rate LHRM(z). The incremental penalty factors (in excess of 2%* margin decrease) are included in the W(z) function of Table 3.2-3.

2.5 TOTAL INTEGRATED RADIAL PEAKING FACTOR - FT (TS 3.2.3)
The calculated value of FrT shall be limited to _<1.60.
The power dependent FK limits are shown on Figure 3.2-3.
The following DNB-related parameters shall be maintained within the limits shown on Table 3.2-2:
