r MAY 4 RECD TENNESSEE VALLEY AUTHORITY CHATTANOOGA. TENNESSEE 374ot 500A Chestnut Street Tower II May 2, 1983 Mr. James R. Tourtellotte, Chairman Regulatory Reform Task Force U.S. Nuclear Regulatory Coinnission Washington, D.C.

Dear Mr. Tourtellotte:
As stated in the March 15, 1983 letter from W. F. Willis, TVA is providing the enclosed cost data for NRC-required backfits on our Browns Ferry and Sequoyah Nuclear Plants. The figures represent our cost estimate for completion of the activity or for the life of the facility, as appropriate.
The costs are actual cost spent to date plus future cost estimates based on 1983 collars and include capital plus operating and maintenance costs.
These costs do not include those associated with extending seneduled outages due to backfits and modifications., The outage of a nuclear unit will require the opemtion of more expensive generating capacity, such as coal-fired units, or the purchase of power from a neighboring utility. For example, the torus modifications at Browns Ferry will prolong two outages on each unit. The first outages on these units have required 163 to 233 days and the second outages are scheduled to last 174 days. The cost of replacement power during the most recent outage was $261,389 a day. A scheduled outage without a major backfit should require 61-66 days. The cost of replacement power due to the impact on the outage duration for the torus modifications will probably exceed the $111 million shown for the capital cost of the backfit, Very truly yours, TENNESSEE VALLEY AUTHORITY l
