TVA's response to Section 2.1 of Enclosure 3 to references 1 and 2 was submitted to you for our Sequoyah Nuclear Plant by my March 1, 1982 letter.

A draft technical evaluation report on the control of heavy loads for our Sequoyah Nuclear Plant was transmitted to TVA by your June 30, 1982 letter to H. G. Parris. A subsequent telephone conversation was held with NRC staff members on December 3, 1982 to discuss TVA comments on the draft technical evaluation report. Enclosed is a supplemental response, which provides additional information and comitments, as requested by the NRC in the December 3, 1982 telephone conversation.
