Re: St. Ld'ie Unit 1Docket No. 50-335Cycle 19 Core Operating Limits Report - Revision 1
Pursuant to St. Lucie Unit 1 Technical Specification (TS) 6.9.1.11 .d, Florida Power & LightCompany (FPL) is submitting the Core Operating Limits Report (COLR) Revision I foroperating cycle 19.
Technical Specification 6.9.1.11.d requires that the COLR, including any mid-cyclerevisions or supplements, be provided to the NRC upon issuance for each reload cycle.This revision to the COLR makes the cycle 19 COLR consistent with the recently approvedLicense Amendment 191. Accordingly, attached is a copy of the St. Lucie Unit 1, Cycle19 Core Operating Limits Report, Revision 1.

2.2 Full Length CEA Position - Misalignment > 15 Inches (TS 3.1.3.1)
The time constraints for full power operation with the misalignment of one full lengthCEA by 15 or more Inches from any other CEA in its group are shown In Figure 3.1-1a.
2.3 Regulating CEA Insertion Limits (TS 3.1.3.6)
The regulating CEA groups shall be limited to the withdrawal sequence and to theInsertion limits shown on Figure 3.1-2, with CEA insertion between the Long TermSteady State Insertion Limits and the Power Dependent Insertion Limits restrictedto:
a. < 4 hours per 24 hour interval,
b. < 5 Effective Full Power Days per 30 Effective Full Power Day interval,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.
During operation, with the linear heat rate being monitored by the Excore DetectorMonitoring System, the AXIAL SHAPE INDEX shall be maintained within the limitsof Figure 3.2-2.
During operation, with the linear heat rate being monitored by the Incore DetectorMonitoring System, the Local Power Density alarm setpoints shall be adjusted toless than or equal to the limits shown on Figure 3.2-1.
