Subject:

Tennessee Valley Authority Nuclear Power Group Response to NRC Regulatory Issue Summary 2014-13 Planned Licensing Action Submittals for All Power Reactor Licensees The purpose of this letter is to provide the Nuclear Regulatory Commission (NRC) staff with the Tennessee Valley Authority (TVA) voluntary response to the NRC Regulatory Issue Summary (RIS) 2014-13 that requested power reactor licensees to voluntarily provide information regarding the number of planned licensing actions to be submitted for NRC review in the next three calendar years and the planned power uprates that will be submitted in the next five calendar years.

Enclosures 1, 2, and 3, to this letter provide the estimated licensing actions for Browns Ferry Nuclear Plant Units 1, 2, and 3, Sequoyah Nuclear Plant Units 1 and 2, and Watts Bar Nuclear Plant, Unit 1, respectively. Watts Bar Nuclear Plant, Unit 2 has not received its operating license; therefore planned Watts Bar Unit 2 licensing actions are not included in this submittal. provides the planned power uprate application information for the Browns Ferry Nuclear Plant Units 1, 2, and 3. As noted in RIS 2014-13, licensee responses to this request are not binding and can be updated as needed.

Nuclear Regulatory Commission CNL-15-138 Page2 August 28, 2015 There are no new regulatory commitments contained in this letter. Should you have any questions, please contact Russ Wells at (423) 751-8130 .
