US New Nuclear Reactor Milestones
Analysis based on 8 articles · First reported Jun 28, 2026 · Last updated Jun 28, 2026
The advancements in small modular reactors by companies like TT News Agency, Aalo Atomics, and Valar Atomics are expected to significantly impact the energy sector by providing cheaper, faster-to-build nuclear power. This could lead to increased investment in nuclear technology and potentially shift energy markets, especially for sectors like data centers and military bases, while also boosting the United States' influence in global energy exports.
Startup TT News Agency became the first company in nearly 50 years to run a new-design nuclear reactor in the United States on June 4 at the United States — Idaho National Laboratory. This milestone, along with similar achievements by Aalo Atomics and Valar Atomics in Idaho and Utah respectively, signals a 'nuclear renaissance' in the US. Driven by billions in private and government funding, and spurred by energy demands from the war in Ukraine and the AI boom, these small modular reactors (SMRs) promise simpler, cheaper, and more versatile nuclear power. Energy Secretary Chris Wright is optimistic about the timeline, expecting hundreds of SMRs by the end of the decade, with some producing electricity next year. These SMRs are being developed for various applications, including US military sites and data centers, and are seen as a tool for American influence abroad.
