Employees at the Department of Energy’s Savannah River Site in South Carolina have demonstrated their resourcefulness and capabilities by implementing a newly created carrier to transport spent nuclear fuel, reducing the time needed to process the material for permanent disposal in coming years.

The Department of Energy’s Manufacturing Demonstration Facility (MDF) at Oak Ridge National Laboratory, in partnership with Kairos Power and Barnard Construction, has successfully developed and validated large-scale, 3D-printed polymer composite forms for casting complex concrete structures.

The test took place at Kairos Power’s Oak Ridge, Tenn., campus, where the Hermes Low-Power Demonstration Reactor is currently under construction.

The United States has tight new deadlines—18 months, max—for licensing commercial reactor designs. The Department of Energy is marshaling the nuclear expertise and high-performance computing assets of its national laboratories, in partnership with private tech companies, to develop generative AI tools and large-scale simulations that could help get nuclear reactor designs through the Nuclear Regulatory Commission’s licensing process—or the DOE’s own reactor pilot program. “Accelerate” and “streamline” are the verbs of choice in recent announcements from Oak Ridge National Laboratory and Idaho National Laboratory, as they describe plans with Atomic Canyon, Microsoft, and Amazon.

At the end of his July 15 speech at the inaugural Pennsylvania Energy and Innovation Summit, President Trump promised that “a lot more [was] going to be announced in the coming week” for the energy and AI sectors.

Leaders from private companies, government, and national laboratories gathered at Argonne National Laboratory on July 17 and 18 for an exclusive AI x Nuclear Energy Executive Summit that the Department of Energy called a first-of-its-kind forum to “align next-generation nuclear systems with the needs of digital infrastructure.”

The Department of Energy announced on June 5 that three companies—all of which are new to the Gateway for Accelerated Innovation in Nuclear (GAIN) voucher program—will receive vouchers to support their research on advanced fuels, materials, and sensors. The second round fiscal year 2025 vouchers will let the companies access specialized research facilities and expertise in the DOE’s national laboratory complex.

Energy Secretary Chris Wright testified before the U.S. Senate’s Energy and Water Development Subcommittee yesterday to discuss how the Department of Energy would be impacted by the president’s proposed fiscal year 2026 budget.

The meeting highlighted concerns from lawmakers about the DOE’s spending and efficiency—pointing to the rise in the department’s budget from $61 billion in FY 2021 to $160 billion last year.

Committee chair John Kennedy (R., La.) called the DOE spending pattern “unsustainable.”

“The average electricity bill . . . for the average American family over the past four years is up 28 percent. That’s the first thing they care about,” Kennedy said. “We’ve got to address it . . . and talk very specifically about what programs are working and what isn’t.”

Workers with Oak Ridge Office of Environmental Management contractor Isotek have surpassed a significant milestone in the supply of medical radioisotopes, extracting more than 15 grams of rare thorium-229 through the Department of Energy’s Thorium Express Project.

The Tennessee legislature has approved a $3.2 million proposal to fund a monument that will honor a group of 85 black former students known as the Scarboro–Oak Ridge 85 who, with support from the Atomic Energy Commission, became the first students to enter a previously white-only public school in the southeastern United States.

"We want to make sure that Oak Ridge and the Scarboro 85 get their rightful place in the civil rights history timeline; we do not want to be left out," said John Spratling, chair of the Scarboro 85 Monument Committee.

ANS recognition: The American Nuclear Society officially recognized and honored the Scarboro 85 in 2021 by awarding the group with the inaugural Social Responsibility in the Nuclear Community Award at that year’s Annual Winter Meeting.

BWX Technologies Inc. has purchased about 97 acres of land in an Oak Ridge, Tenn., industrial park where the company expects to build a uranium enrichment facility using a technology called DUECE, or, Domestic Uranium Enrichment Centrifuge Experiment. DUECE was developed at Oak Ridge National Laboratory to provide enriched uranium for the Department of Energy’s National Nuclear Security Administration, and BWXT is several months into a yearlong engineering study to evaluate options for deploying a centrifuge pilot plant using DUECE.

Oak Ridge National Laboratory has successfully removed legacy radioactive waste stored for more than five decades, marking a significant cleanup milestone. The Oak Ridge Office of Environmental Management (OREM) and cleanup contractor UCOR processed and shipped highly radioactive source material, including radium-226 and boron, out of state for permanent disposal.

Fusion startup Type One Energy has announced the publication of a baseline physics design basis for its proposed Infinity Two stellarator fusion pilot power plant. The design basis was published in a series of seven papers in a special issue of the Journal of Plasma Physics. According to the company, the design basis realistically considers for the first time the relationship between competing requirements for plasma performance, power plant startup, construction logistics, reliability, and economics utilizing actual power plant operating experience.

Researchers at Oak Ridge National Laboratory have demonstrated a new method to track chemical changes in molten salt, according to a March 17 announcement from the Department of Energy’s Office of Nuclear Energy.

A virtual meeting between representatives of the West Valley Demonstration Project (WVDP) in New York and the Oak Ridge Office of Environmental Management (OREM) in Tennessee was held recently to share lessons learned from the ongoing demolition of West Valley’s main plant process building.

When I graduated from Scranton University in 1956 with a B.S. in physics, I was in awe of the nuclear era and determined to be part of a nuclear future. Fortunately, I landed a position with Pratt & Whitney Aircraft as part of the Aircraft Nuclear Propulsion program. The position included a one-year assignment as a visiting staff member at Oak Ridge National Laboratory.

Oak Ridge National Laboratory has for the first time designed, printed, and irradiated a specimen capsule—or rabbit capsule—for use in its High Flux Isotope Reactor (HFIR), the Department of Energy announced on January 15.

FLiBe—a mixture of lithium fluoride and beryllium fluoride—is not an off-the-shelf commodity. The Department of Energy suspects that researchers and reactor developers may have a use for the 2,000 kilograms of fluoride-based salt that once ran through the secondary coolant loop of the Molten Salt Reactor Experiment (MSRE) at Oak Ridge National Laboratory.

Federal and contractor officials, community leaders, and educators gathered in Knoxville, Tenn., on October 29 for a roundtable event focused on ensuring the Oak Ridge Office of Environmental Management (OREM) and its partners have the resources and infrastructure needed to support a robust, talented workforce in the years ahead.

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.

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.
