Over the past two weeks, Argonne National Laboratory has announced numerous significant advancements being made by its staff to push forward nuclear fuels and materials research. Those announcements include the opening of the new Activated Materials Lab, the development of a new measurement technique, and the application of new artificial intelligence tools.

I spent a fair amount of time over the holiday break pondering the makings of a good year for nuclear technology in 2026.

Last year was white-­hot. Between the fundamental upward shift in domestic electricity demand, the continuing proliferation of data center projects in all corners of the U.S., the increasingly voracious appetite of the financial markets for nuclear investment, and the Trump administration’s full-­throttle approach to nuclear policy, 2025 will likely be remembered as a significant, positive inflection point in the history of the harnessed atom.

I hope 2026 will be even better, but for it to be so, it will have to be different. It needs a seriousness about it, a scrape of the froth. Advanced nuclear energy technology is in a hardening phase at the moment, where the green shoots of innovation must now grow into robust commercial enterprises capable of scaling quickly and safely. Not everyone will succeed.

Idaho National Laboratory and computer chip maker Nvidia have announced a public-private partnership to advance nuclear energy deployment through artificial intelligence. According to INL, the collaboration aims to cut reactor development times in half and reduce operational costs by 50 percent by using AI to design, license, manufacture, construct, and operate reactors with human-in-the-loop workflows.

The Department of Energy’s newly published Genesis Mission National Science and Technology Challenges describes 26 challenges and corresponding AI solutions designed to advance the artificial intelligence–focused Genesis Mission, which was established by presidential executive order last November to develop an “integrated platform that connects the world’s supercomputers, experimental facilities, AI systems, and unique datasets across every major scientific domain to double the productivity and impact of American research and innovation within a decade.”

Utah-based Creekstone Energy has signed a memorandum of understanding (MOU) with EnergySolutions to study the feasibility of building at least 2 gigawatts of advanced nuclear capacity to power a 25-acre data center Creekstone is planning in Delta, Utah.

In a flurry of announcements this week, NextEra Energy confirmed new deals across the energy sector with Symmetry, Meta, Basin Electric, WPPI Energy, and Google. These deals are primarily focused on enabling more nuclear build-out for the artificial intelligence boom.

One of the executive orders issued by President Trump in November —“Launching the Genesis Mission”—focuses on a national effort to accelerate the use of AI in scientific research. The Genesis Mission EO preceded a reorganization of the Department of Energy and further tightens links between science and security under the administration’s quest for “global technology dominance in the development of artificial intelligence.”

As President Trump hosted Saudi Crown Prince Mohammed bin Salman at the White House on November 19, Energy Secretary Chris Wright confirmed that the United States and Saudi Arabia have signed a “historic” deal on cooperation in the civilian nuclear energy sector. The “Joint Declaration on the Completion of Negotiations on Civil Nuclear Cooperation” is seen as an important part to strengthen U.S. influence in the Gulf region to counter the influence of Iran, Russia, and China.

AI for energy, and energy for AI: that is the new refrain. But can nuclear power plants be deployed at the pace needed for substantial and timely contributions to the energy infrastructure? For Westinghouse, delivering its AP1000 on time and on budget in the United States is a challenge not yet accomplished, while newcomers like Aalo Atomics are turning to AI to speed design, permitting, and construction.

During speeches at the American Nuclear Society’s Winter Conference & Expo, happening this week in Washington, D.C., Energy Secretary Chris Wright and Nuclear Regulatory Commission Chair David Wright both promised that the Trump administration will speed up nuclear reviews so the U.S. can maintain leadership in nuclear energy.

The DOE’s Wright took a stab at the NRC’s traditionally slow bureaucratic processes in approving primarily large light water reactors in the past, saying that the agency needs to speed up to meet the greater demand for new small modular reactors.

The Department of Energy’s Office of Environmental Management has issued a request for offer (RFO) seeking proposals from U.S. companies to build and power AI data centers on the DOE’s Paducah Site in Kentucky. Companies are being sought to potentially enter into one or more long-term leasing agreements at the site that would be solely funded by the applicants.

The Department of Energy, Argonne National Laboratory, NVIDIA, and Oracle have agreed to a public-private partnership to deliver the DOE’s largest AI supercomputers, named Solstice and Equinox.

A new AI software tool for monitoring and controlling the plasma inside nuclear fuel systems has been developed by an international collaboration of scientists from Princeton University, Princeton Plasma Physics Laboratory (PPPL), Chung-Ang University, Columbia University, and Seoul National University. The software, which the researchers call Diag2Diag, is described in the paper, “Multimodal super-resolution: discovering hidden physics and its application to fusion plasmas,” published in Nature Communications.

The Department of Energy’s Office of Environmental Management and Office of Science and the National Nuclear Security Administration issued requests for proposals last month, seeking plans from companies to build AI data centers at the Oak Ridge Reservation, the Savannah River Site, and Idaho National Laboratory.

More than 300 delegates from around the world attended the OECD Nuclear Energy Agency’s recent Roadmaps to New Nuclear 2025 conference in Paris, France. In attendance were representatives from governments, industry, public and private financial sectors, academia, legal firms, think tanks, and research institutions. Cohosted by the Korean government, the event focused on practical, near-term solutions to barriers facing nuclear new builds.

The International Atomic Energy Agency presented its 2025 Global ISOP Innovation Award for AI to Blue Wave AI Labs, Constellation, and the Southern Company subsidiary Southern Nuclear for the companies’ collaborative work on Blue Wave's ThermalLimits.ai. The technology is an AI application that provides accuracy in online thermal limit forecasting for boiling water reactors.

The Nuclear Regulatory Commission will host a hybrid public workshop on September 24 from 9 a.m. to 5 p.m. (EDT) to discuss its activities for the safe and secure use of artificial intelligence in NRC-regulated activities.

As interest and investment grows around AI applications in nuclear power plants, there remains a gap in standardized benchmarks that can quantitatively compare and measure the quality and reliability of new products.

Nuclear-tailored AI developer Atomic Canyon is moving to fill that gap by entering into a new strategic partnership with Idaho National Laboratory to develop and release the “first comprehensive benchmark suite for evaluating retrieval-augmented generation (RAG) and large language models (LLMs) in nuclear applications.”

Nuclearn, the nuclear AI start-up cofounded by Bradely Fox, one of Nuclear News’s 40 Under 40 honorees for 2024, announced it has raised $10.5 million in Series A funding to accelerate product development and market expansion of its AI platform for nuclear plant operations.

Rhoades

Mudrick

Longtime nuclear industry executive Chris Mudrick has been named the new chief nuclear officer at Constellation Energy, effective September 29. He will take over the position from Dave Rhoades, who is retiring from the role.

History: Mudrick has been Constellation’s senior vice president of generation growth since December 2024, a position that marked his return to the company after serving as executive vice president and CNO at Bruce Power in Ontario, Canada, for more than four years. Prior to joining Bruce Power, Mudrick was at Constellation/Exelon for more than 32 years, ending his time there as senior vice president of operations–East and chief operating officer. He began his career with the company as a nuclear power plant operator in Pennsylvania in 1987.
