Los Alamos National Laboratory researchers have performed a critical experiment using high-assay low-enriched uranium (HALEU) TRISO fuel. It is the nation’s first criticality safety experiment using HALEU fuel in more than 20 years. On November 21, LANL announced the work of its Deimos team, which earlier this year carried out an experiment at the National Criticality Experiments Research Center (NCERC), operated by LANL at the Nevada National Security Site.

Recently published research done at Brookhaven National Laboratory is offering a new, high-energy method for studying the structure of atomic nuclei. Scientists have been using the Solenoidal Tracker at the Relativistic Heavy Ion Collider (RHIC), known as STAR, to track the particles produced by ion collisions in the particle accelerator. Their research was published earlier this month in Nature.

Seeking spacecraft that can “maneuver without regret,” the U.S. Space Force is investing $35 million in a national research team led by the University of Michigan to develop a spacecraft with an onboard microreactor to produce electricity, with some of that electricity used for propulsion. But this spacecraft would not be solely dependent on nuclear electric propulsion—it would also feature a conventional chemical rocket to increase thrust when needed.

A software algorithm developed at Oak Ridge National Laboratory has reduced the time needed to inspect 3D-printed parts for nuclear applications by 85 percent, the Department of Energy announced on November 1, and that algorithm is now being trained to analyze irradiated materials and nuclear fuel at Idaho National Laboratory.

Special issue of Nuclear Technology planned on the RELAP5 reactor modeling code

October 25, 2024, 9:55AMNuclear News

Nuclear reactor design and analysis never stops, and engineers have an extensive computational toolbox from which to draw for their work. Since 1979, one such tool has been the RELAP5 modeling and simulation software. Now, American Nuclear Society journal Nuclear Technology has announced plans for a special issue dedicated to RELAP5 developments and applications.

Submission of abstracts is open now; email guest editor George Mesina by November 15 to express interest.

A breakthrough in the understanding of the properties of nuclear structure has been achieved by an international team of scientists comprising researchers from Massachusetts Institute of Technology, Fermi National Accelerator Laboratory, University of Munster in Germany, and Institute of Nuclear Physics at the Polish Academy of Sciences. The team, from the nCTEQ collaboration investigating nuclear parton (quark and gluon) distribution functions, developed a quark-gluon model that combined low-energy and high-energy concepts to reproduce the properties of atomic nuclei.

On October 8, the Department of Energy’s Idaho Operations Office released the draft environmental assessment (EA) Demonstration of Microreactor Experiment (DOME) Test Bed Operations. The draft EA assesses the potential environmental impacts of plans to use the containment dome of the former Experimental Breeder Reactor-II at Idaho National Laboratory’s Materials and Fuels Complex (MFC) to test multiple TRISO-fueled advanced reactor designs on a micro scale.

The only nuclear reactor in Australia has returned to power after a monthslong shutdown for planned essential maintenance and upgrades. The OPAL (for open-pool Australian light water reactor) research reactor at the Australian Nuclear Science and Technology Organization (ANSTO) campus in Sydney successfully went through the most significant engineering maintenance and upgrade project in its 17-year history.

New uranium and fluorine detection method set to boost nuclear safeguards

By combining two techniques, analytical chemists at Oak Ridge National Laboratory have for the first time simultaneously detected fluorine and different uranium isotopes in a single particle. Quickly detecting both elements together may help International Atomic Energy Agency inspectors determine if and when undisclosed enrichment has taken place. The findings, published in the Journal of the American Chemical Society, “push the limit” of how fast single particles can be characterized in terms of their chemical, elemental, and isotopic compositions, according to a September 26 news release from ORNL.

I really think so. Especially after visiting Abilene Christian University’s new Dillard Science and Engineering Research Center, the home of the Nuclear Energy Experimental Testing (NEXT) Lab and where the university will test its new molten salt research reactor design. The visit was part of the 12th Thorium Energy Alliance Conference. NEXT Lab director and program manager Rusty Towell anticipates that the research reactor will be operational in two years, and I believe it will. What was most impressive is that the reactor is suited to be scaled to any size from small to large—a key feature in any decarbonized world.

New research into the dynamics and structure of high-temperature liquid uranium trichloride (UCl3) salt—a potential fuel for molten salt reactors—has been published in the Journal of the American Chemical Society. A recent news release from Oak Ridge National Laboratory describes how researchers from ORNL, Argonne National Laboratory, and the University of South Carolina used ORNL’s Spallation Neutron Source (SNS) to document the unique chemistry of liquid UCl3 “for the first time.”

When a SpaceX rocket lifted off from Kennedy Space Center on September 10 (see video here), sending a crewed commercial mission into low Earth orbit, an experiment designed by Pacific Northwest National Laboratory was onboard. Several high-purity metal samples will orbit Earth and absorb cosmic radiation for five days—including that from the Van Allen radiation belt—to help the lab answer questions about the radiation environment for manned space missions, according to a news release from PNNL.
