7 Crystal River Unit 3, Cycle 11 1.0 Cor: Cperating 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.1 " 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, BAW-2262, Rev. I dated December 1997, and BAW-2262 Rev. 3 dated June 1999.
Note that BAW-2262 Rev. 2 examined the impact of an error in accounting for Gadolinium (Gd) pins on the Cycle 11 Linear Heat Rate-to-Centerline Fuel Melt limits. FCF did not apply the proper uncertainty to account for Gd pin loading. However, by taking advantage of margin in ]
l the maneuvering analyses, the existing limits were found to remain bounding. The revision did I not require a change to the COLR.
The following limits are included in this report.

Crystal River Unit 3, Cycle 11 Refueling Boron Concentration The boron concentration must be greater than 3013 ppmb 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 final Cycle 10 burnup exceeds 610 EFPD. The 610 EFPD refueling concentration is 2%7. The actual end of cycle 10 was 592.790 EFPD @ 2544 MWt or 587.25 @
2568 MWt. Using this value and the equation above the refueling boron increases to 3013 ppmb. 3 This limit is referred to by Technical Specification LCO 3.9.1 l

4 Crystal River Unit 3, Cycle 11 Revision History Revision 0 - Original Cycle 11 Release Approved 3/21/96 PRC Meeting #96-12 Revision 1 - Revised to include nuclear enthalpy rise hot channel factor limits and added
. information to shutdown margin discussion. An ITS Basis change relative to the rod insertion limits in the COLR was made, but did not affect the rod insertion data in the COLR.
Revision 2 - Revised to include new Lower Limit (End of Cycle 11) for Moderator Temperature Coefficient. To correct a minor formatting deficiency in Revision 1, the column width of the Mark B4Z Linear Heat Rate Limits was adjusted to more fully show the LHR data for the high burnup limit (60GWD/MT).
