TVA President and CEO Don Moul described the application as a key step forward: “TVA has put in the work to advance the design and develop the first application for the BWRX-300 technology, creating a path for other utilities who choose to build the same technology.” He emphasized that deploying new nuclear solutions is vital for providing affordable, reliable electricity to American households and businesses for decades.
The BWRX-300, a 300 MWe water-cooled SMR with passive safety systems, builds on the design of GE Vernova Hitachi’s ESBWR boiling water reactor. TVA has collaborated with Ontario Power Generation, Polish company Synthos Green Energy, and GE Vernova Hitachi Nuclear Energy to refine the standard design. Additionally, TVA leads a coalition of utilities and supply chain partners that has applied for a $800 million US Department of Energy grant to accelerate the construction of the nation’s first SMR, alongside an $8 million grant to support the licensing process.
SMRs, like the BWRX-300, feature a compact, modular design compared to traditional nuclear reactors. TVA highlights that these reactors offer enhanced safety, faster construction, easier operation, and better integration into landscapes due to their smaller size. The Clinch River site already holds an early site permit, confirming its suitability for nuclear development based on safety, environmental, and emergency planning assessments. TVA has also submitted an Environmental Report and plans to begin site preparation as early as 2026.
Craig Ranson, President and CEO of GE Vernova Hitachi Nuclear Energy, noted the significance of the project: “TVA’s investment in the standard design of the BWRX-300 technology will accelerate its deployment, helping meet the rising demand for energy and enhancing energy security.” He also referenced Ontario’s recent approval to construct the Western world’s first SMR, underscoring the technology’s progress.
