Dear Mr. Campbell:

By letters dated June 25, 2004, the Tennessee Valley Authority (TVA) submitted amendment requests for Browns Ferry Nuclear Plant (BFN), Units 2 and 3, as supplemented by letters dated August 23, 2004, February 23, April 25, June 6, and December 19, 2005, February 1 and 28, March 7, 9, 23 and 31, April 13, May 5 and 11, June 12, 15, 23 and 27, July 6, 21, 24, 26, and 31, December 1, 5, 11 and 21, 2006, January 31, February 16, and 26, and April 6, 18 and 24, July 27, August 13, and 21, and September 24, 2007. The proposed amendment would change the BFN operating licenses for Units 2 and 3 to increase the maximum authorized power level by approximately 15 percent.

In a letter dated November 7, 2006, TVA reported changes in the modeling used to determine compliance with emergency core cooling system requirements. The enclosed Request for Additional Information is related to this submittal.

A response to the enclosed Request for Additional Information is needed before the Nuclear Regulatory Commission staff can complete the review. This request was discussed with Mr. James Emens of your staff on October 3, 2007, and it was agreed that TVA would respond within 15 days of issuance of this letter.

If you have any questions, please contact me at (301) 415-2315.
