' y McGuire 1 Cycle 26 Core Operating Limits Report Implementation Instructions For Revision 1 Revision Description and CR Tracking MCEI-0400-349 Page2 Revisi.on 1 Revision O of the McGuire Unit 1 Cycle 26 .COLR contains limits specific to the reload core. Revision 1 of the McGuire Unit 1 Cycle 26 COLR is issued to adjust the burnup dependent minimum required CLA boron concentration for bumups > 200 EFPD. The revised values reflect the actual Cycle N-1 shutdown conditions, as opposed to applying an assumed shutdown window. Revision 1 is being issued in accordance with NCR 02190882.

The power distribution monitoring factors from Appendix A of Revision O remain valid and are not transmitted as part of Revision 1. Implementation Schedule The McGuire Unit 1 Cycle 26 COLR requires the reload 50.59 (AR #02147708) be approved prior to implementation and fuel loading. Revision 1 to the McGuire Unit 1 Cycle 26 COLR is effective upon receipt. The McGuire Unit 1 Cycle 26 COLR will cease to be effective during No MODE between cycles 26 and 27. Data Files to be Implemented No data files are transmitted as part of this document.
