 SMRs at TVA’s Clinch River Nuclear Site.  The permit is valid through 2039 and therefore provides TVA a great deal of flexibility to make new nuclear decisions based on energy needs and economic factors.  In 2021, TVA initiated a Programmatic EIS ("PEIS") that evaluated a variety of alternatives for a proposed advanced nuclear technology park at the Clinch River Nuclear Site and will provide additional flexibility for future decision making.  The Record of Decision was signed in 2022.  In the second quarter of 2025, TVA requested public comment on a draft Supplemental EIS that addresses the potential environmental effects associated with site preparation, construction, operation, and decommissioning of one SMR at the Clinch River site.  In May 2025, TVA submitted a construction permit application to the NRC for an SMR at the Clinch River Site, and the NRC accepted the application for review in July 2025.  In addition, while evaluating alternatives for potential advanced nuclear at the Clinch River Nuclear Site, TVA is exploring the feasibility of applying a similar approach that could deploy additional SMRs at Clinch River and other TVA-owned properties.

The TVA Board has approved up to $350 million to explore advanced reactor technology options under the New Nuclear

Program.  Of this amount, TVA had spent $251 million as of September 30, 2025.  In addition, TVA and a consortium of co-applicants applied for a U.S. Department of Energy ("DOE") grant to support the future development of a small modular reactor at TVA's Clinch River site in January 2025 and submitted a revised application in April 2025.  See Funding Opportunities below.  The New Nuclear Program provides a systematic roadmap for TVA’s exploration of advanced nuclear technology,  and collaboration with other interested parties will be an important aspect of this program.  In December 2022, TVA entered into a multi-party collaborative arrangement to advance the global deployment of the GE Vernova Hitachi Nuclear Energy ("GVH") 

68

BWRX-300 SMR.  GVH is responsible for standard design development.  See Note 22 — Collaborative Arrangement for additional information.  See also Other Nuclear below.

The decision to potentially build SMRs continues to be part of the ongoing discussion as part of the asset strategy for TVA’s future generation portfolio, and any future decision to construct any reactor, advanced or otherwise
