Subject: Oconee Nuclear Station, Units 1, 2, and 3

Docket Nos. 50-269, -270, -287 Proposed Technical Specification Amendment Oconee Unit 1, Cycle 14 Reload Report

Gentlemen:

On May 7, 1991 I submitted a proposed amendment to the Oconee Nuclear Station

(ONS) facility operating licenses and revisions to the ONS Technical

Specifications consisting of changes to support operation of Unit 1 at full power

during Cycle 14 and future fuel cycle designs for all Oconee units. Supporting

technical justification for the proposed changes was provided in Attachment 3,

"Oconee Unit 1, Cycle 14, Reload Report," to the referenced letter.

The purpose of this letter is to advise the NRC that the five figures provided

in Attachment to this letter were inadvertently omitted from Attachment 3 to my letter of May 7, 1991. Accordingly, these figures are submitted herein for

inclusion in Attachment 3 to my original submittal.

Should you have further questions, please feel free to contact M. A. Haghi at

(704) 373-4060.

Very truly yours,

M. S. Tuckman
