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.
