During a state visit to the White House by Japanese prime minister Fumio Kishida on April 10, the Department of Energy announced that U.S. and Japanese agencies had cooperated to remove all high-enriched uranium (HEU) from the Japan Materials Testing Reactor Critical Assembly (JMTRC) of the Japan Atomic Energy Agency (JAEA) two years ahead of schedule.

Imagine what our world would be like today without the benefits of electric energy. Think of the inventions and technologies that never would have been. Think of a world without power grids and the electricity that makes them run. Without this power, we’d find it difficult to maintain our industrial and manufacturing bases or enable advancements in the fields of medicine, communications, and computing.
Now consider the moon, our closest celestial neighbor about which we still know so little, waiting for modern-day explorers in spacesuits to unveil its secrets. Lunar exploration and a future lunar economy require reliable, long-lasting, clean sources of power. Nuclear fission answers that call. When assessing the application of nuclear power in space, three Ps should be considered: the present, the potential, and the partnerships.

Researchers at the Department of Energy’s Princeton Plasma Physics Laboratory are using a stellarator they designed and built using permanent rare-earth magnets and a 3D-printed shell to help test new fusion power concepts. MUSE—the first stellarator built at PPPL in 50 years—took one year to construct and generated its first plasma in February 2023. The work that went into its design has already inspired a stellarator power plant concept being developed by a commercial spin-off, Thea Energy.

Once used for applications in medicine, industry, and research, many countries now have legacy radium-226 sources, according to the International Atomic Energy Agency. With the support of the IAEA’s technical cooperation program, these disused sealed radioactive sources are being recovered, and countries are improving national capacities for their long-term management, including their potential reuse and recycling.

The U.S. Department of Energy is constructing the Electron-Ion Collider (EIC) at Brookhaven National Laboratory to explore the boundaries of nuclear physics—both for the sake of science and to support diverse applications, including in nuclear medicine, radiation safety, and nuclear energy. The project, already supported by international collaborators in 40 countries, just secured a significant commitment from the United Kingdom.

The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

Staff and researchers at Penn State’s Radiation Science and Engineering Center (RSEC) will work this year to install a small angle neutron scattering (SANS) device and become the first and only U.S. university research reactor to host SANS capability. The $9.8 million device, donated by Helmholtz Zentrum Berlin (HZB) in Germany, will help researchers determine the structure of organic materials such as polymers, complex fluids, and biomolecules.

The Department of Energy’s Office of Clean Energy Demonstrations issued a final environmental assessment (EA) and finding of no significant impact in February for a cost-shared X-energy project to construct and operate a helium test facility (HTF) in Oak Ridge, Tenn. According to the EA, construction would begin in early 2024 and take X-energy and its contracted partner, Kinectrics, about one year to complete. the facility would then operate for six years, with the possibility of extensions for up to an additional 20 years, to test equipment for a demonstration of X-energy’s high-temperature, gas-cooled reactor technology and also to “serve the reactor community at large as the technology continues to develop and is adopted around the world.”

A team of engineers, physicists, and data scientists from Princeton University and the Princeton Plasma Physics Laboratory (PPPL) have used artificial intelligence (AI) to predict—and then avoid—the formation of a specific type of plasma instability in magnetic confinement fusion tokamaks. The researchers built and trained a model using past experimental data from operations at the DIII-D National Fusion Facility in San Diego, Calif., before proving through real-time experiments that their model could forecast so-called tearing mode instabilities up to 300 milliseconds in advance—enough time for an AI controller to adjust operating parameters and avoid a tear in the plasma that could potentially end the fusion reaction.

The International Atomic Energy Agency is developing multiple methods to rapidly screen and authenticate the origin of foods like extra virgin olive oil. With recent heat waves and droughts affecting olive oil yields in Europe—which produces 60 percent of all olive oils—the European Commission has a problem: a growing black market in fake virgin and extra virgin olive oils. According to a 2022 EC report, olive oil is one of the most mislabeled food products in Europe.

Type One Energy Group announced plans on February 21 to relocate its headquarters from Madison, Wis., to the Tennessee Valley Authority’s (TVA) Bull Run fossil plant in Clinton, Tenn., where it will build a stellarator fusion prototype machine. According to the company, the construction of the stellarator—called Infinity One—could begin in 2025, if necessary environmental reviews, partnership agreements, permits, and operating licenses are all in hand.

As hydrogen production increases worldwide, some see clean hydrogen as a game-changer when it comes to decarbonizing the steel industry.
Steel production is one of the “hard-to-abate” sectors of industry, which are responsible for about 30 percent of global carbon emissions. These industries are tough to decarbonize because the technologies either do not yet exist or are considered uneconomical.
Researchers have been working frantically to develop an array of materials and fibers to economically extract uranium from seawater—and they have succeeded. PNNL scientists exposed this special uranium-sorbing fiber developed at ORNL to Pseudomonas fluorescens and used the Advanced Photon Source at Argonne National Laboratory to create a 3-D X-ray microtomograph to determine microstructure and the effects of interactions with organisms and seawater.

America, Japan, and China are racing to be the first nation to make nuclear energy completely renewable. The hurdle is making it economical to extract uranium from seawater, because the amount of uranium in seawater is truly inexhaustible.
While America had been in the lead with technological breakthroughs from the Department of Energy’s Pacific Northwest and Oak Ridge National Laboratories, researchers at Northeast Normal University in China have sprung ahead. But these breakthroughs from both countries have brought the removal of uranium from seawater within economic reach. The only question is when will the source of uranium for our nuclear power plants change from mined ore to seawater extraction?
Radioisotopes target cancer, improve imaging, and have myriad other medical uses

On August 2, 1946, 1 millicurie of the isotope carbon-14 left Oak Ridge National Laboratory, bound for the Barnard Free Skin and Cancer Hospital in St. Louis, Mo.
That tiny amount of the radioisotope was purchased by the hospital for use in cancer studies. And it heralded a new peacetime mission for ORNL, built just a few years earlier for the production of plutonium from uranium for the Manhattan Project.
After nearly eight years of valuable service as editor of the American Nuclear Society journal Fusion Science and Technology, Leigh Winfrey has indicated that she intends to step down from the position as of June 2025, providing an opportunity for a fresh voice to lead FST. Consequently, ANS is seeking a qualified individual to fill this position.
