The Department of Energy’s Office of Fusion Energy Sciences (FES) wants Fusion Innovation Research Engine (FIRE) collaboratives to be a bridge between FES’s basic science research programs and the growing fusion industry. A funding opportunity announcement released May 22 explains that FIRE will be a “transformative initiative aimed at creating a fusion innovation ecosystem” with virtual, centrally managed collaboratives working on “end-use inspired” fusion science and technology R&D.

The DIII-D National Fusion Facility is starting up after an eight-month experimental hiatus, equipped with new and improved plasma control and diagnostic systems. The upgrades will help researchers from around the nation and the world resolve key physics questions to bridge the gap between current magnetic confinement fusion research and the first fusion power pilot plants. General Atomics, which operates DIII-D for the Department of Energy, announced the completion of upgrades on May 8.

Cecilia Payne-Gaposchkin: The woman who first grasped the elemental power of stars

May 10, 2024, 12:00PMNuclear News

When the U.S. Fusion Energy Outreach Team declared the second week of May as Fusion Energy Week, they were recognizing the May 10 birthday of Cecilia Payne-Gaposchkin—the British-born American astronomer who applied principles of quantum physics, chemistry, and astronomy to become the first to realize—at the age of 25—that stars and the universe itself are mostly composed of hydrogen and helium, and that the stars could be sorted by their spectra into groups that corresponded to the temperature of the stars.

The image on the right is a closer view showing the top half of the tokamak and plasma. The coils are used to generate the magnetic field perturbations that produce the islands (blue). Another coil can also be found on the bottom of the machine. The injection system for the ECCD microwaves is depicted on top (red). These can be used to adjust the width of the islands.

The Max Planck Institute for Plasma Physics (IPP) announced that it recently has achieved a new record for ion current density for neutral particle heating at its ELISE (Extraction from a Large Ion Source Experiment) experimental testing facility in Garching, Germany. ELISE is being used to test neutral beam injection (NBI) systems that will be used to heat the plasma of the ITER fusion experiment in France.

Steam is a sign of cooling system function . . . at ITER

Steam from one of ITER’s ten induced-draft cooling cells offers visual confirmation of a successful cooling system test, the ITER organization announced April 30. ITER’s cooling system features 60 kilometers of piping with pumps, filters, and heat exchangers that can pull water through at up to 14 cubic meters per second. Once fully operational, two cooling loops—one to remove the heat generated by the plasma in the ITER tokamak and one for its supporting infrastructure—will be capable of extracting up to 1,200 MW of heat.

Fusion Energy Week begins today

Fusion is riding a surge of attention that began in December 2022 when researchers at Lawrence Livermore National Laboratory’s National Ignition Facility achieved fusion ignition. The organizers of Fusion Energy Week—a group called the U.S. Fusion Outreach Team—on the other hand, trace fusion development back 100 years to the doctoral research of Cecilia Payne-Gaposchkin, who discovered that stars, including our Sun, are mostly made of hydrogen and helium, which in turn led to the understanding that those elements are the “fuel” of potential fusion energy systems on Earth. In recognition of Payne-Gaposchkin’s birthday—May 10—the U.S. Fusion Outreach Team plans to hold a “grassroots celebration of fusion energy” May 6–10, 2024, and annually during the second week of May.

Bipartisan Fusion Energy Act pushes for regulatory clarity

Sen. Alex Padilla (D., Calif.) introduced the Fusion Energy Act (S. 4151) last month with a bipartisan group of cosponsors—John Cornyn (R., Texas), Cory Booker (D., N.J.), Todd Young (R., Ind.), and Patty Murray (D., Wash.). The legislation would codify the Nuclear Regulatory Commission’s regulatory authority over commercial fusion energy systems to streamline the creation of clear federal regulations that will support the development of commercial fusion power plants—and would require a report within one year on a study of risk- and performance-based, design-specific licensing frameworks for “mass-manufactured fusion machines.”

“Congress must do everything in its power to ensure continued U.S. leadership in developing commercial fusion energy facilities,” said Padilla as he introduced the bill. “The Fusion Energy Act would provide regulatory certainty for investors as the NRC develops and streamlines frameworks for such facilities.”

Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

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.

As the world shifts toward clean and sustainable energy, Kazakhstan stands on the cusp of a significant move into nuclear energy. Kazakh president Kassym-Jomart Tokayev has suggested a national referendum to gauge the country’s position on building a nuclear power plant, setting the stage for an in-depth discussion about the nation’s energy trajectory.

Plasma oscillation has fusion energy implications

March 20, 2024, 3:00PMANS Nuclear Cafe

Researchers from the University of Rochester in New York and the University of California–San Diego have published a paper in Physical Review Letters describing a previously unknown class of plasma oscillations. In “Space-Time Structured Plasma Waves,” the researchers “demonstrate that electrostatic wave packets structured with space-time correlations can have properties that are independent of the plasma conditions,” such as “density, temperature, ionization state, or details of the distribution functions.” This finding is technologically relevant, the authors note, because “electrostatic waves play a critical role in nearly every branch of plasma physics from fusion to advanced accelerators, to astro, solar, and ionospheric physics.”

Nuclear noted as an answer to electricity demands from data centers

March 12, 2024, 9:30AMANS Nuclear Cafe

The spread of “electricity-hungry data centers and clean-technology factories” throughout the United States is “leaving utilities and regulators grasping for credible plans to expand the nation’s creaking power grid,” according to a recent article in the Washington Post. According to the report, the surge in industrial power requirements due to such factors as innovation in artificial intelligence (AI) and the corresponding construction of large computing infrastructure, is prompting some officials to “look beyond the grid” to ease the “grid bottleneck” and meet electricity demands.

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.
