Crystal River Unit 3, Cycle 10 1.0 Core Operating Limits This Core Operating Limits Report for CR3 Cycle 10 has been prepared in accordance with the requirements of Technical Specification Section 1.1 and 5.6.2.18. The analytical methods used to determine the core operating limits shall be those previously reviewed and approved by the NRC. These methods are documented in BAW-10179PA, " Safety Critera and hiethodology for Acceptable Cycle Reload Analyses", SER dated 3/16/93. BAW-10187P,

" Statistical Core Design for B&W Designed.177 FA Plants", SER dated 3/24/93. BAW-2149-A, " Evaluation of Replacement Rods in BWFC Fuel Assemblies", dated September 1993. Application of the methodology for API and RPI position indication agreement was approved in SER dated June 25,1992.

The following limits are included in this report.

Crystal River Unit 3, Cycle 10 Refueline Boron Concentration The boron concentration must be greater than 2880 ppmb Note: The refueling boron concentration must be increased by 2 ppmb for every EFPD the final Cycle 9 burnup is less than 545 EFPD. The refueling boron concentration can be reduced 1.4 ppmb for every EFPD that the final Cycle 9 burnup exceeds 545 EFPD. The 545 EFPD refueling concentration is 2897. The actual end of cycle 9 was 557.2264 EFPD.-

Using this value and the equation above the refueling boron reduces to 2880 ppmb.
