Decommissioning Funding Assurance
References:
Letter from TVA to the NRC dated July 30, 2009, "Decommissioning Funding Assurance" The referenced letter from the Tennessee Valley Authority (TVA) described several letters and teleconference exchanges between TVA and the NRC which addressed decommissioning funding levels for TVA's operating nuclear units. The enclosure to the referenced letter also provided tables addressing decommissioning funding levels and obligations, including the difference between the NRC minimum required amount and the projected total amount of funding assurance for each of TVA's licensed units.
In the referenced letter, TVA indicated that a plan including one or more of the funding methods described in regulations would be presented to the TVA Board and that the Board's next meeting was scheduled for August 20, 2009. The letter concluded by indicating that TVA expected that it would to be able to inform the NRC of the details of the TVA Board-approved plan to address decommissioning funding assurance by September 4, 2009. The purpose of this letter is to provide NRC with details of the plan.

U.S. Nuclear Regulatory Commission Page 2 September 4, 2009 The enclosed table describes an external sinking fund approach that provides decommissioning funding assurance for each nuclear unit at the end of its respective term of licensed operation. A fund balance is projected for each remaining year of unit operation. This approach uses the decommissioning cost estimates, funding levels, and assumptions regarding the real rate of return described in the tables provided as an enclosure to TVA's July 30, 2009, letter. In accordance with NRC regulations, TVA will annually review the minimum amount to be provided for decommissioning funding assurance. As a result of that annual review, TVA will update the projected fund balances as appropriate.
TVA plans to meet or exceed the projected annual fund balances for each unit as reflected in the table. As necessary, TVA will make contributions to the funds for each unit, or apply another method or combination of methods of funding assurance consistent with NRC regulations and guidance (NRC Regulatory Guide 1.159, Revision 1).
This letter contains no regulatory commitments. Please direct any questions concerning this matter to Fred Mashburn at (423) 751-8817.
