SUBJECT: MEETING SUMMARY - WATTS BAR - TO DISCUSS PLANT PERFORMANCE ANDASSOCIATED ON-GOING ACTIVITIES

Dear Mr. Kingsley:

This letter refers to the management meeting conducted at your request at theRegion II office October 29, 1996. The purpose of the meeting was to discussplant performance and associated on-going activities.

It is our opinion that this meeting was beneficial and provided a betterunderstanding of TVA's activities associated with the Watts Bar facility.

In accordance with Section 2.790 of the NRC's "Rules of Practice" Part 2,Title 10 Code of Federal Regulations, a copy of this letter and its enclosureswill be placed in the Public Document Room.

Should you have any questions concerning this letter, please contact me.

Sincerely,
