There is no CR associated with this revision. Implementation Schedule The McGuire Unit 1Cycle26 COLR requires the reload 50.59 (AR #02147708) be approved prior to implementation and fuel loading. Revision 0 may become effective any time during No MODE between cycles 25 and 26, but must become effective prior to entering MODE 6 which starts cycle 26. 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.

McGuire 1 Cycle 26 Core Operating Limits Report Appendix A Power Distribution Monitoring Factors MCEI-0400-349 Page 31 Revision 0 Appendix A contains power distribution monitoring factors used in Technical Specification Surveillance. This data was generated in the McGuire 1 Cycle 26 Maneuvering Analysis calculation file, MCC-1553.05-00-0640. Due to the size of the monitoring factor data, Appendix A is controlled electronically within Duke and is not included in the Duke internal copies of the COLR. The Plant Nuclear Engineering Section will control this information via computer file(s) and should be contacted if there is a need to access this information. Appendix A is included in the COLR copy transmitted to the NRC.
