Research & Applications

At Idaho National Laboratory, researchers have built a bridge between computer models and the lab’s Microreactor Applications Research Validation and Evaluation (MARVEL) microreactor.

Tony Crawford, an INL researcher and MARVEL’s reactivity control system lead, designed a phone booth–sized surrogate nuclear reactor called ViBRANT, or Visual Benign Reactor as Analog for Nuclear Testing, which uses light instead of neutrons to show a “nuclear” reaction.

As the energy sector faces mounting pressure to grow at an unprecedented pace while maintaining reliability and affordability, nuclear technology remains an essential component of the long-­term solution. Southern Company stands out among U.S. utilities for its proactive role in shaping these next-­generation systems—not just as a future customer, but as a hands-­on innovator.

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.”

A team of nuclear safety experts with the International Atomic Energy Agency completed a five-day safety review of the SAFARI-1 reactor in Pelindaba, South Africa, focusing on aging management and continued safe operation of the 61-year-old 20-MW research reactor.

The IAEA team found that the SAFARI-1’s management and technical staff had a strong commitment to and involvement with the assessment but recommended that formal programs be established to address the aging reactor’s equipment.

The newest addition to Oak Ridge National Laboratory’s materials research facilities is set to host a ribbon-cutting ceremony later this year now that construction is complete and laboratories are being phased into operation. The 100,000-square-foot, multipurpose Translational Research Capability building at ORNL houses a broad spectrum of research ranging from quantum science to energy storage, with several of the largest labs in the building focused on materials challenges for applications including nuclear fission and fusion, like the ORNL’s Corrosion Lab.

Many people are familiar with Godzilla as a giant reptilian monster that emerged from the sea off the coast of Japan, the product of radioactive contamination. These days, there is a new Godzilla, but it has a positive—and entirely fact-based—association with nuclear energy. This one has emerged inside the Tokamak Assembly Preparation Building of ITER in southern France.

Sometimes, cops and robbers is more than just a kid’s game. At the Department of Energy’s national laboratories, researchers are channeling their inner saboteurs to discover vulnerabilities in next-generation nuclear reactors, making sure that they’re as safe as possible before they’re even constructed.

Idaho National Laboratory has brought its newest high‑performance supercomputer, named Teton, online and made it available to users through the Department of Energy’s Nuclear Science User Facilities program. The system, now the flagship machine in the lab’s Collaborative Computing Center, quadruples INL’s total computing capacity and enters service as the 85th fastest supercomputer in the world.

Westinghouse Electric Company, Nordion, and PSEG Nuclear announced on Tuesday the signing of long-term agreements to establish the first commercial-scale production of cobalt-60 in a U.S. nuclear reactor. Under the agreements, the companies are to apply newly developed production technology for pressurized water reactors to produce Co-60 at PSEG’s Salem nuclear power plant in New Jersey.

Researchers at Argonne National Laboratory have developed a multiphysics simulation modeling tool to predict how feedwater heater (FWH) tubes in a nuclear power plant break down over time. The model, which has the potential to improve maintenance schedules and save operating costs at nuclear facilities, is described in a paper titled “Numerical Analysis with Experimental Validation of Tube Fatigue Failure in Feedwater Heaters,” published in a recent issue of Engineering Failure Analysis.

A uranium enrichment monitor developed by a team at Pacific Northwest National Laboratory will soon be undergoing testing for nonproliferation applications at the International Atomic Energy Agency Centre of Excellence for Safeguards and Non-Proliferation in the United Kingdom. A recent PNNL news article describes how the research team, led by nuclear physicist James Ely, who works within the lab’s National Security Directorate, developed the UF₆ gas enrichment sensor (UGES) prototype for treaty verification and other purposes.

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.”

The Nuclear Regulatory Commission announced that it has received the first portion of a construction permit application from Oklo subsidiary Atomic Alchemy that requests permission to build four nonpower reactors for a radioisotope production facility at Idaho National Laboratory. The submission is now available for public inspection on the NRC website.

A new type of material has been demonstrated to greatly enhance the ability to recover uranium from seawater, according to a study published recently in Sustainable Carbon Materials. The research, which could lead to a new way of obtaining uranium for nuclear reactor fuel, was conducted by scientists from Weifang University and North China Electric Power University.

The “space race” is once again making headlines, with technology worthy of the 21st century. Like the Cold War–era competition, this race too is about showcasing power—but this time it's nuclear power.

A new article in Power Technology examines the competing efforts of the United States, Russia, and China as they strive to be the first to put a nuclear reactor on the moon to power a lunar base, detailing the technical challenges and international rivalries.

In a letter to the Office of the U.S. Trade Representative, the Source Security Working Group (SSWG) is urging the U.S. government to withhold from imposing tariffs on Canadian-orgin cobalt-60 and to preserve the duty-free treatment of the radioisotope.

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.

Zeno Power, a developer of nuclear batteries, is to receive americium-241 recovered from Orano’s La Hague nuclear fuel recycling site in Normandy, France, under a strategic agreement announced by the companies on September 24.

The Department of Energy announced on Wednesday that it has awarded $134 million in funding for two programs designed to secure U.S. leadership in emerging fusion technologies and innovation. The funding was awarded through the DOE’s Fusion Energy Sciences (FES) program in the Office of Science and will support the next round of Fusion Innovation Research Engine (FIRE) collaboratives and the Innovation Network for Fusion Energy (INFUSE) awards.
