Indiana Michigan Power Company 500 Circle Drive Buchanan, Ml 49107 1395 MICHIGAN POWER September 15, 2003 AEP:NRC:2691-34 Docket Nos. 50-315 50-316 U. S. Nuclear Regulatory Commission Attn: Document Control Desk Mail Stop O-P1-17 Washington, DC 20555-0001 Donald C. Cook Nuclear Plant Units 1 and 2 MONTHLY OPERATING REPORT Pursuant to the requirements of Donald C. Cook Nuclear Plant Unit 1 and Unit 2 Technical Specification 6.9.1.8, the attached Monthly Operating Report for August 2003 is submitted.

Additionally, the following Unit Shutdowns and Power Reductions summaries are being resubmitted due to errors in the calculation of the duration hours: Unit 1 and Unit 2 - February 2003; Unit 1 - May 2003; and Unit 2 - June 2003. These summaries incorrectly reported reactor shutdown hours instead of generator shutdown hours for those periods.

There are no new commitments associated with this submittal.

Should you have any questions, please contact Mr. Brian A. McIntyre, Manager of Regulatory Affairs, at (269) 697-5806.

Sincerely, John . Zwolinski Director, Design Engineering and Regulatory Affairs JEN/jen Attachment
