Argonne National Laboratory said it has secured just over $10 million from the Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) for two research projects investigating the transmutation of spent nuclear fuel into less radioactive substances.

The National Reactor Innovation Center is accepting applications from developers ready to take a fueled microreactor to criticality inside the former Experimental Breeder Reactor-II containment building at Idaho National Laboratory, now repurposed as DOME—a microreactor test bed. According to a Department of Energy announcement, DOME will be ready to receive the first experimental reactor in the fall of 2026, with testing likely to begin in 2027.

Kairos Power announced this morning that safety-related nuclear construction has begun at the Oak Ridge, Tenn., site where the company is building its Hermes low-power test reactor. Hermes, a scaled demonstration of Kairos Power’s fluoride salt–cooled, high-temperature reactor technology, became the first non–light water reactor to receive a construction permit from the Nuclear Regulatory Commission in December 2023. The company broke ground at the site in July 2024.

Curiosity landed on Mars sporting a radioisotope thermoelectric generator (RTG) in 2012, and a second NASA rover, Perseverance, landed in 2021. Both are still rolling across the red planet in the name of science. Another exploratory craft with a similar plutonium-238–fueled RTG but a very different mission—to fly between multiple test sites on Titan, Saturn’s largest moon—recently got one step closer to deployment.
On April 25, NASA and the Johns Hopkins University Applied Physics Laboratory (APL) announced that the Dragonfly mission to Saturn’s icy moon passed its critical design review. “Passing this mission milestone means that Dragonfly’s mission design, fabrication, integration, and test plans are all approved, and the mission can now turn its attention to the construction of the spacecraft itself,” according to NASA.

Idaho National Laboratory is looking for a sponsor to invest $5 million–$10 million in a privately funded innovation incubator to support seed-stage start-ups working in nuclear energy, integrated energy systems, cybersecurity, or advanced materials. For their investment, the sponsor gets access to what INL calls “a turnkey source of cutting-edge American innovation.” Not only are technologies supported by the program “substantially de-risked” by going through technical review and development at a national laboratory, but the arrangement “adds credibility, goodwill, and visibility to the private sector sponsor’s investments,” according to INL.

The International Atomic Energy Agency announced that its Nuclear Technology for Controlling Plastic Pollution (NUTEC Plastics) initiative has partnered with Ecuador’s Oceanographic Institute of the Navy (INOCAR) and Polytechnic School of the Coast (ESPOL) to build microplastic monitoring and analytical capacity to address the growing threat of marine microplastic pollution in the Galapagos Islands.

Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

The Department of Energy announced March 31 that a new Molten Salt Flow Loop Test Bed at Idaho National Laboratory recently went through its inaugural test run. The closed-loop test system will allow for continuous monitoring and analysis of chloride-based molten salt reactor technology and instruments before the construction of the Southern Company/TerraPower Molten Chloride Reactor Experiment. MCRE—an experimental fast-spectrum molten salt research reactor—will be built at INL’s repurposed Zero Power Physics Reactor, which has been renamed LOTUS (Laboratory for Operation and Testing in the United States).

Savannah River National Laboratory said it has received a patent for its radially oriented honeycomb structures. The technology offers a solution to the deformation of cylindrical honeycomb structures when they are formed from flat panels, providing a way to create structures with greater wall thickness than traditional methods.

Scientists at Idaho National Laboratory continue to make progress on the Molten Chloride Reactor Experiment (MCRE), which entails research and development for the first operational advanced nuclear reactor to use a mixture of molten chloride salt and uranium as fuel and coolant. The experiment is evaluating the safety and physics of the molten chloride fast reactor that Southern Company and TerraPower are planning to build.

A team from Idaho National Laboratory and the Department of Energy’s Office of Nuclear Energy recently visited Carolina Fabricators Inc. (CFI) in West Columbia, S.C., to launch the fabrication process for the primary coolant system of the MARVEL microreactor. Battelle Energy Alliance, which manages INL, awarded the CFI contract in January.
