The U.S. nuclear energy sector has seen a surge in momentum over the past two weeks, marked by key regulatory steps for small modular reactors (SMRs), landmark commercial agreements with major tech firms, and continued federal investment to accelerate nuclear deployment as part of the broader clean energy transition.
SMRs Move Closer to Deployment
A major development came from the Tennessee Valley Authority (TVA), which formally submitted the nation’s first construction permit application for a small modular reactor to the Nuclear Regulatory Commission (NRC). The project, located at the Clinch River site in Tennessee, will use GE Hitachi’s BWRX-300 design, a next-generation light water SMR. This milestone underscores TVA’s leadership in next-gen nuclear deployment. It is also part of a broader industry-led coalition that has applied for $800 million in cost-shared funding from the U.S. Department of Energy (DOE) to support the deployment of the BWRX-300, with commercial operation targeted for 2033. GE Hitachi’s reactor design—already approved by Canadian regulators and under construction near Toronto—is gaining momentum as a viable option for decarbonized baseload generation in the U.S. and beyond.
Tech Sector Embraces Nuclear for AI and Data Growth
Private-sector demand for clean, reliable energy is also bolstering the nuclear sector. On May 30, Meta announced a 20-year deal to purchase nuclear power from Constellation Energy’s Clinton Clean Energy Center in Illinois. The agreement is part of Meta’s strategy to power its expanding AI and data infrastructure with carbon-free electricity around the clock. The move reflects a growing trend among technology companies to secure long-term nuclear supply to meet the energy needs of large-scale computing, data centers, and AI model training. Google, Amazon, and Microsoft have also recently voiced support for expanding nuclear energy deployment globally.
In line with this momentum, several major tech firms recently endorsed the international goal of tripling nuclear generation capacity by 2050, highlighting a sharp shift in sentiment among corporate leaders toward embracing nuclear as a climate-aligned energy solution.
Federal Research and Testing Resumes
On the research front, Idaho National Laboratory (INL) completed a safety test on high-burnup fuel for fast reactors—the first such test in more than two decades. This U.S.-Japan collaborative project marks a return to advanced fuel qualification testing and is critical for future reactor designs that require new types of fuel with greater efficiency and performance. The test reflects a strategic shift by the U.S. Department of Energy to reinvigorate its domestic research infrastructure in support of advanced nuclear technologies, as competition from international nuclear suppliers intensifies.
Policy and Market Outlook
The Trump administration’s current nuclear energy policy is pressing forward to rapidly expand U.S. nuclear infrastructure, fast-track new reactor designs, revitalize the nuclear fuel cycle, and integrate nuclear into defense and AI critical infrastructure. To enable this, it has dismantled regulatory barriers, loosened oversight, and restructured federal roles—moves applauded by industry but criticized by safety and oversight advocates.
Still, challenges remain. Critics argue that nuclear projects face long permitting timelines, high upfront costs, and uncertain economics compared to renewables and storage. However, industry leaders contend that SMRs, long-term power purchase agreements, and federal loan guarantees are helping to shift the balance in favor of scalable nuclear solutions.
