High-assay low-enriched uranium (HALEU) production has also progressed significantly. On April 9, 2025, the DOE allocated HALEU to five advanced reactor developers, a move ANS endorsed as essential for next-generation reactors. Southern Nuclear’s test of 6% enriched U-235 fuel at the Vogtle Unit 2 in 2025 improved fuel efficiency, reducing costs and fostering a domestic fuel supply chain.
This aligns with Trump’s aim to reduce foreign energy dependence, enhancing economic competitiveness by powering tech industries, such as Google and Amazon’s data centers, which require reliable energy to drive AI innovation.
Small modular reactors (SMRs) and microreactors are advancing rapidly.
The Tennessee Valley Authority’s Clinch River project, moving toward a construction permit for GE-Hitachi’s BWRX-300 SMR, promises scalable power for rural and industrial areas.
Holtec International also plans to build two of its SMR-300 small modular reactors at the Palisades nuclear power plant site in Michigan. These SMRs are designed to produce 300 megawatts of power each, which will significantly increase total output by roughly 75%. The Holtec SMR-300’s are projected to be installed by 2030.
The Defense Innovation Unit’s ANPI program, updated on April 10, 2025, targets microreactor deployment at military bases by 2026, bolstering energy resilience. The American Nuclear Society, ANS, praised these as economic catalysts, with private investments like Amazon’s $334 million SMR deal creating high-tech jobs and infrastructure growth in regions like Oak Ridge, Tennessee. GE-Hitachi’s testing of steel-concrete composite blocks at Purdue University, reported by ANS, further reduces SMR construction costs, while BWX Technologies’ new Oak Ridge facility for HALEU enrichment supports job creation and fuel production.
In addition, the continued deployment of new Generation III+ reactors (one gigawatt-plus) is still in play. Georgia and South Carolina are among states already expressing an interest in building full-sized nuclear Westinghouse AP-1000 reactors, which are already operating at Georgia’s Vogtle plant in Waynesboro. The United States has been successful in selling large Westinghouse AP-1000 reactors to Poland and Bulgaria, and Westinghouse potentially has another market in Canada, as well as more plants under construction in China.
The US would do well to continue to build out the full nuclear ecosystem here at home. The ANS-backed ADVANCE Act (2024) streamlines NRC licensing, and Trump’s January 2025 executive order easing nuclear permitting has boosted investor confidence. Tech partnerships, including Google’s 500 MW deal with Kairos Power, underscore nuclear’s role in powering high-growth sectors, aligning with Trump’s economic vision.
