1.0 Core Operating Limits This Core Operating Limits Report for CR3 Cycle 11 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, Rev. I " Safety Critera and Methodology for Acceptable Cycle Reload Analyses", NRC Letter R.

Jones to J.H. Willoughby dated January 22,1996. The Cycle 11 limits generated using this methodology above are documented in BAW-2262, " Crystal River Unit 3 Cycle 11 Reload Report", dated January 1996 The following limits are included in this report.

  • Crystal River Unit 3. Cycle 11 4 Refueling Bbron Concentration The boron concentration must be greater than 3013 ppmb i

Note: The refueling boron concentration must be increased by 2 ppmb for every EFPD the final Cycle 10 burnup

is less than 610 EFPD. The refueling boron concentration can be reduced 2.0 ppmb for every EFPD that the j final Cycle 10 burnup exceeds 610 EFPD. The 610 EFPD refueling concentration is 2967. The actual end of j cycle 10 was 592.790 EFPD @ 2544 MWt or 587.25 @ 2568 MWt. Using this value and the equation above 4

the refueling boron increases to 3013 ppmb.
