First Light Fusion announced last week that it has set a new record for the highest quartz pressure achieved on Sandia National Laboratories’ Z machine using its amplifier technology to achieve an output pressure of 3.67 terapascal (TPa)—roughly doubling the pressure the company reached in its first experiment on the machine one year ago.

Fleischmann

U.S. Rep. Chuck Fleischmann is all about energy—specifically nuclear energy.

On March 20, the GOP congressman from Tennessee joined the official launch of Atoms for Appalachia, the new report from the Atlantic Council Global Energy Center that studied opportunities for deploying advanced nuclear energy in the area to spur economic development.

The council hosted a series of Atoms for Appalachia (A4A) workshops in 2024 in North Carolina, Pennsylvania, Tennessee, and West Virginia in partnership with the Breakthrough Energy Foundation. The sessions explored workforce demand, partnership opportunities, and innovation happening across the nuclear industry.

Scientists at Idaho National Laboratory continue to make progress on the Molten Chloride Reactor Experiment (MCRE), which entails research and development for the first operational advanced nuclear reactor to use a mixture of molten chloride salt and uranium as fuel and coolant. The experiment is evaluating the safety and physics of the molten chloride fast reactor that Southern Company and TerraPower are planning to build.

The French magnetic confinement fusion tokamak known as WEST maintained a plasma in February for more than 22 minutes—1,337 seconds, to be precise—and “smashed” the previous record plasma duration for a tokamak with a 25 percent improvement, according to the CEA, which operates the machine. The previous 1,006-second record was set by China’s EAST just a few weeks prior. Records are made to be broken, but this rapid progress illustrates a collective, global increase in plasma confinement expertise, aided by tungsten in key components.

The ITER organization (IO) recently published an article asking, “Have you ever wondered what it’s like inside an operating tokamak?” For speculative answers, the international nuclear fusion project turned to electrical engineer Michael Walsh, the new head of ITER’s Fusion Technology—Instrumentation & Control Division and previous head of ITER’s Diagnostics Division.

Merz

The conservative Christian Democratic Union came out on top in Germany’s February 23 election. CDU leader Friedrich Merz achieved a “lackluster win,” as the Associated Press termed it, but his party’s political agenda could mean a revival for nuclear energy in Germany.

The country shut down its final nuclear reactor in 2023, in large part as a reaction to the 2011 accident at Japan’s Fukushima Daiichi nuclear plant. Now many Germans are taking a renewed interest in clean, reliable nuclear power.

First, Merz and the CDU need to form a coalition to secure at least 316 votes in Parliament before he can be formally elected chancellor of Germany, the AP reports. Provisional results shared by Politico show that the CDU carried 28.5 percent of Sunday’s vote, trailed by the Alternative for Germany Party with 20.8 percent, the Social Democratic Party with 16.4 percent, and Alliance 90/the Greens with 11.6 percent.

Stellarator fusion energy company Type One Energy will collaborate with private equity firm Pine Island New Energy Partners (PINEP) to accelerate the maturation of a more robust supply chain for the fusion energy industry, the companies announced last week.

Type One Energy said it has entered into a cooperative agreement with the Tennessee Valley Authority to jointly develop plans for a potential TVA fusion power plant project in the Tennessee Valley region using Type One Energy stellarator fusion power technology. The company said its 350-MWe fusion pilot power plant, named Infinity Two, could provide a complementary source of baseload electrical generation for the region as early as the mid-2030s.

The University of California–San Diego has joined a new research collaborative focused on overcoming critical obstacles in developing and scaling up inertial fusion power plants. Led by San Diego-based General Atomics, the group was one of six research teams that were collectively awarded $107 million in January by the Department of Energy as part of the Fusion Innovative Research Engine (FIRE) Collaboratives.

University of Tennessee–Knoxville’s Department of Nuclear Engineering highlighted the Computational Research Access Network (CRANE) program in a recent article on its website. CRANE is a free online program “that teaches computational methods in nuclear fusion to students from underrepresented backgrounds,” said Alyssa Hayes, a nuclear engineering Ph.D. candidate at UTK. Hayes is the first chair of the board of directors of the CRANE nonprofit organization.

The Department of Energy announced six Fusion Innovative Research Engine (FIRE) collaboratives set to receive funding of $107 million on January 16. The six selected teams represent a first round of awards from a funding opportunity announcement released in May 2023 as part of the DOE Office of Fusion Energy Sciences’ (FES) goal of creating a “fusion innovation ecosystem.”

Another calendar year has passed. Before heading too far into 2025, let’s look back at what happened in 2024 in the nuclear community. In today's post, compiled from Nuclear News and Nuclear Newswire are what we feel are the top nuclear news stories from July through September 2024.

Stay tuned for the top stories from the rest of the past year.

Commonwealth Fusion Systems (CFS) has announced that it plans to build a fusion power plant, named ARC, at the James River Industrial Park in Chesterfield County, Va.—and that it expects to be the first company to make fusion power available at grid scale.

Last week's inaugural ministerial meeting of the IAEA World Fusion Energy Group (WFEG), in Rome, Italy, drew government ministers and senior officials who represented “dozens of countries” interested in fusion energy technology.

Leadership of the United Kingdom’s STEP (Spherical Tokamak for Energy Production) fusion program has transitioned to U.K. Industrial Fusion Solutions Ltd. (UKIFS), a wholly owned subsidiary of the U.K. Atomic Energy Authority (UKAEA). UKIFS was established in February 2023 to lead a public-private partnership that will design, build, and operate the STEP prototype fusion energy plant in Nottinghamshire in England’s East Midlands region.

With more than 40 fusion development companies announcing plans and funding, it’s hard for a newcomer to stand out, but Pacific Fusion is giving it a try. The company, based in Fremont, Calif., was founded in summer 2023 and emerged from “stealth mode” last Friday with $900 million in committed funding from investors, a team that includes people directly involved in the successful ignition experiments at Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), and a technical paper that makes a case for a pulsed magnetic fusion approach to fusion energy.

Commercial nuclear power is illegal in Australia, and it has been since the 1990s. This past June, however, the country’s main opposition party announced plans to build seven commercial nuclear reactors in the 2030s and 2040s on sites presently occupied by aging coal-fired plants—should the party’s Liberal–National Coalition win power in federal elections next year. This statement has reignited a public debate regarding the potential role of nuclear energy in Australia.

In the foothills of the Rocky Mountains on the outskirts of Fort Collins, Colo.—home to Colorado State University—work began this month on a new laser facility funded by a public-private partnership. The private portion is $150 million from Marvel Fusion, announced in August 2023, while $12.5 million—the latest funding for CSU from the Department of Energy’s Office of Fusion Energy Sciences (FES)—will support the new facility as part of LaserNetUS, a laser research network operated by DOE-FES to provide access to laser facilities for multidisciplinary researchers from the United States and abroad.

Earlier this month, General Atomics made its Fusion Synthesis Engine (FUSE) software available to others who want to design and build magnetic confinement fusion power plants.

The Department of Energy announced yesterday a total of $49 million in funding for 19 projects in the Foundational Fusion Materials, Nuclear Science, and Technology programs that span functional and structural materials R&D for heating technology, magnet technology, blankets, fuel cycle, and first wall research.
