Dear Mr. Seyfrit:

The Omaha Public Power District submitted a response to IE Bulletin79-01B dated April 17, 1980, which indicated that additional aging datafor electrical cables for the Fort Calhoun Station was forthcoming.Accordingly, the attached pages, C-9 through C-13, are provided.Several change pages are also provided to update information containedin the District's original submittal. Specifically, valve HCV-545 isdeleted from page C-28 and resubmitted as page C-28A, due to its failedposition being improperly identified. In addition, page C-0 is cor-rected to indicate a " Note 2", which was previously omitted.

Sincerely,. \
