More people in low- and middle-income countries who have head and neck cancer may be able to access lifesaving radiotherapy after research supported by the International Atomic Energy Agency has shown that fewer—but higher—doses of radiation treatment resulted in clinical outcomes similar to standard radiotherapy treatments. Reducing overall treatment times for this type of cancer through a treatment regimen called hypofractionation could help countries navigate resource constraints and shorten waitlists, enabling more patients to receive treatment while also reducing the cost and duration of care. The IAEA announced the findings in a news article published January 22.

Argonne’s newest beamline uses heavy ions to degrade a material’s properties as much in a day as a nuclear reactor does in a year, without introducing radioactivity. That’s according to an article published January 16 by Argonne National Laboratory. The Argonne Tandem Linac Accelerator System (ATLAS) now boasts a new beamline—the ATLAS Material Irradiation Station, or AMIS—that uses the accelerator’s lowest high-energy beams to displace atoms and mimic the degradation of materials inside an operating reactor over time. AMIS makes it easier and faster to test candidate fuel and structural materials for existing and future reactors.

The International Atomic Energy Agency, in cooperation with Argentina, launched a scientific research expedition on January 6 to study microplastics in Antarctica—one of the planet’s most remote areas—as part of an effort to combat widespread microplastic pollution.

A new type of cold spray coating, made from the metal tantalum and applied to the plasma-facing steel walls of fusion reactors, could lead to efficient, compact fusion reactors that are easy to repair and maintain, according to a study recently published in the journal Physica Scripta. The study was led by scientists and engineers at the University of Wisconsin–Madison and involved researchers from South Korea, France, and Germany.

The same high energy density that makes nuclear energy a clean and efficient source of power could make it a good alternative to defend the planet against catastrophic asteroid impacts. NASA demonstrated the world’s first planetary defense technology in September 2022 by deliberately crashing a “kinetic impactor”—a heavy, box-like spacecraft—into an asteroid. Now, researchers at Lawrence Livermore National Laboratory have developed a new tool to model how a nuclear device could deflect—or even destroy—an asteroid threat to Earth in a more efficient and controlled way.

The Office of Fusion Energy Sciences (FES) in the Department of Energy’s Office of Science introduced a new plan—"Building Bridges: A Vision for the Office of Fusion Energy Sciences”—during a Fusion Energy Sciences Advisory Committee (FESAC) hearing on December 13, and announced that news December 14. What’s included? A plan for the DOE to “establish the steps needed to help advance fusion energy, including addressing key science and technology gaps in the supply chain and industry.” The vision is less a guiding document than a preview of DOE-FES’s near-term intentions, which include drafting a fusion science and technology road map in 2024 to shape investments for the coming decade.

“The tools of the academic designer are a piece of paper and a pencil with an eraser. If a mistake is made, it can always be erased and changed. If the practical-reactor designer errs, he wears the mistake around his neck; it cannot be erased. Everyone sees it.”
Many in the nuclear community are familiar with this sentiment from Admiral Rickover. A generation of stagnation in the industry has underscored the truth of his words. But as economies around the world put a price on carbon emissions, there’s a renewed sense of urgency to deploy clean energy technologies. This shifts the global balance of economic competitiveness, and it’s clear that the best path forward for nuclear requires combining the agility of private innovators with the technology and capabilities of national laboratories.

The Department of Energy recently announced that it was establishing three inertial fusion energy (IFE) hubs and funding them with a total of $42 million over four years. The leaders of the three hubs selected by competitive peer review—Colorado State University, Lawrence Livermore National Laboratory, and the University of Rochester—all issued press releases touting the attributes and plans of their facilities and their research collaborators on the same day—December 7.
