The University of Illinois–Urbana-Champaign, in partnership with Nano Nuclear Energy, has submitted a construction permit application to the Nuclear Regulatory Commission for construction of a Kronos micro modular reactor (MMR). This is the first major step in the two-part 10 CFR Part 50 licensing process for the research and test reactor and is the culmination of years of technical refinement and regulatory alignment.
The team chose to engage with the NRC in a preapplication readiness assessment, providing the agency with draft versions of the majority of the CPA’s technical content for feedback, which is expected to ensure a high-quality application.
Radiation can change polymers in ways that enable their use in many industrial and healthcare applications. A new IAEA coordinated research project will explore how machine learning can improve prediction of structural changes in polymers caused by ionizing radiation. (Image: IAEA)
The International Atomic Energy Agency has launched a new coordinated research project (CRP) aimed at creating a database of polymer-radiation interactions in the next five years with the long-term goal of using the database to enable machine learning–based predictive models.
Radiation-induced modifications are widely applicable across a range of fields including healthcare, agriculture, and environmental applications, and exposure to radiation is a major factor when considering materials used at nuclear power plants.

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.

Texas A&M University’s Engineering Experimental Station (TEES) is collaborating with Houston-based start-up ZettaJoule to explore the potential construction of a nonpower research reactor at the university’s College Station campus.
The university believes that hosting ZettaJoule’s ZJ high-temperature, gas-cooled reactor might lead to as much as $1 billion worth of research collaborations, industrial partnerships, and federal funding for its College of Engineering.

Kairos Power has completed shielded radiation performance testing on a full-scale precast concrete structure at the company’s Reactor Demonstration Campus in Oak Ridge, Tenn., involving the use of an iridium-192 source to measure the movement of radiation through the concrete’s walls, joints, and seams. Kairos expects the results to contribute to schedule and cost estimates for its planned commercial power plants.

The Thomas Jefferson National Accelerator Facility is leading research supported by two Department of Energy Advanced Research Projects Agency–Energy (ARPA-E) grants aimed at developing accelerator technology to enable nuclear waste recycling, decreasing the half-life of spent nuclear fuel.
Both grants, totaling $8.17 million in combined funding, were awarded through the Nuclear Energy Waste Transmutation Optimized Now (NEWTON) program, which aims to enable the transmutation of nuclear fuels by funding novel technologies for improving the performance of particle generation systems.

Idaho National Laboratory has announced that the National Reactor Innovation Center’s Molten Salt Thermophysical Examination Capability (MSTEC) facility will begin operations in March 2026.
Providing testing capabilities for molten salts, including fuel salts, MSTEC extends INL’s abilities to advance molten salt reactor technology and provide data needed for safe reactor deployment.

A new strategic partnership is providing Kairos Power with the expertise and specialized facilities of Oak Ridge National Laboratory to help accelerate the development of the California-based company’s Hermes. This partnership is the fourth between ORNL and Kairos Power since 2020, and it is focused in part on the manufacture and management of TRISO fuel pebbles for the fluoride salt–cooled, high-temperature demonstration reactor now under construction in Oak Ridge, Tenn.

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.

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.
