DPR-58 and DPR-74 MODIFICATION TO OUR PREVIOUS SUBMITTAL AEP:NRC:1071E; REVISED FIGURES FOR THE LOSS OF LOAD EVENT U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, D.C. 20555 Attn: T. E. Hurley April 6, 1990

Dear Hr. Murley:

The purpose of this letter is to update our previous submittal AEP:NRC:1071E. The changes provided herein are corrections to the documentation in Appendix B of the VANTAGE 5 Reload Transition Safety Report for Donald C. Cook Nuclear Plant Unit 2, January 1990, supplied by our contractor, Westinghouse. The update is attached to this submittal.

The update, which is editorial in nature, consists of revised figures for the loss of load event. Westinghouse has informed us that these revisions have no impact on the conclusions noted in our previous submittal. These figures replace the corresponding figures previously submitted in Attachment 4, Appendix B of our submittal AEP:NRC:1071E. The figures transmitted with AEP:NRC:1071E did not correspond to the bounding case.

We apologize for any inconvenience this update may cause you or your staff.

This document has been prepared following Corporate procedures that incorporate a reasonable set of controls to ensure its accuracy and completeness prior to signature by the undersigned.

Sincerely, M. P. Alexich Vice President 90/-
