U.S. Nuclear Regulatory Commission Page 2 March 31, 2011 In accordance with the requirements of 10 CFR 50.75(f)(1), the Tennessee Valley Authority (TVA) is reporting on the status of decommissioning funding for Browns Ferry Nuclear Plant (BFN), Units 1, 2, and 3; Sequoyah Nuclear Plant (SQN), Units 1 and 2; and Watts Bar Nuclear Plant (WBN), Unit 1. The reporting requirements and corresponding TVA information are provided below.

1. The amount of decommissioning funds estimated to be required pursuant to 10 CFR 50.75(b) and (c):

Decommissioning cost estimates were calculated using the formulas provided in NUREG-1307, Revision 14, "Report on Waste Burial Charges," utilizing the waste burial adjustment factors for Generic Low-Level Waste (LLW) Disposal Site and Direct Disposal with Vendors. Bureau of Labor Statistics indices for the end of the 2010 calendar year were taken from the sources referenced by NUREG-1 307.

The calculated estimates for the end of calendar year (CY) 2010 are provided in Table 1 below.

2. The amount accumulated in the TVA decommissioning fund at the end of the calendar year 2010 for the items included in 10 CFR 50.75(b) and (c):

TVA's decommissioning fund balances at the end of CY 2010 are provided below in Table 2.

BFN, Unit 1 164.95 BFN, Unit 2 157.71 BFN, Unit 3 142.01 SQN, Unit 1 227.45 SQN, Unit 2 216.43 WBN, Unit 1 105.79

U.S. Nuclear Regulatory Commission Page 3 March 31, 2011 Note that these fund balances are all in excess of the 2010 fund balances required for each plant based on the updated TVA plan provided in Enclosure 1 and discussed under item 3, below.

3. A schedule of the annual amounts remaining to be collected for items in 10 CFR 50.75(b) and (c):

By letter dated March 31, 2009 (Reference 1), TVA reported that due to a downturn which resulted in lower market valuations for many investments held in TVA's decommissioning trust fund, the decommissioning trust fund balances for TVA's BFN, SQN, and WBN were below Nuclear Regulatory Commission (NRC) minimum required amounts. Subsequently, by letter dated September 4, 2009 (Reference 2), TVA provided NRC with the details of a plan which utilized an external sinking fund approach to provide decommissioning funding assurance for each nuclear unit at the end of its respective term of licensed operation. The NRC staff reviewed TVA's plan and determined that it provides reasonable assurance of adequate decommissioning funding at the time permanent termination of operations is expected (Reference 3). to this letter provides TVA's updated plan for providing decommissioning funding for each of its operating nuclear reactors based on the cost estimates at the end of CY 2010. This plan constitutes the schedule of the annual amounts remaining for items in 10 CFR 50.75(b) and (c). TVA will continue to follow the plan reflected in Enclosure 1, as updated.

TVA discussed the updated plan. provided in Enclosure 1 with the NRC during a conference call on March 23, 2011. During that call, the NRC requested that TVA recalculate the plan provided in Enclosure 1 using actual fund balances for each of the units at the end of CY 2010. For information only, Enclosure 2 provides the results of this recalculation.

4. The assumptions used regarding rates of escalation in decommissioning costs, rates of earnings on decommissioning funds, and rates of other factors used in funding projections:

The assumed escalation in decommissioning costs is 4 percent.

TVA assumed a projected annual real rate of return on decommissioning funds of 5 percent, as authorized by the TVA Board of Directors, TVA's rate-making authority.

5. Any contracts upon which the licensee is relying pursuant to 10 CFR 50.75(e)(1)(v):

None.

U.S. Nuclear Regulatory Commission Page 4 March 31, 2011

6. Any modifications occurring to a licensee's current method of providing financial assurance since the last submitted report:

None.

7. Any material changes to trust agreements.

None.

If you have any questions concerning this matter, please contact Josh Perrel at 423-751-7737.
