Welcome to Fusion Energy Base's first-ever Confinement Time, a brief roundup of news from around the world concerning fusion energy progress.

Whyte's month

Professor Dennis Whyte should be a familiar name at this point to anyone who has been following fusion for the last few decades. This month Whyte was appointed CEO of the UK Atomic Energy Authority (UKAEA), the organization that previously ran the Joint European Torus (JET), still runs the Mega Ampere Spherical Tokamak (MAST) Upgrade, and is delivering the Spherical Tokamak for Energy Production (STEP).

Whyte is also a co-founder of Commonwealth Fusion Systems (CFS), (where he holds no publicly listed operational or board role), is still listed as a professor at the Massachusetts Institute of Technology (MIT) at the time of writing, and is a co-founder of the fusion investment firm Rutherford Energy Ventures (REV). Leading the UKAEA is a serious commitment, and notably REV has already named Dr. Guinevere Shaw as its new CEO.

Policy and Infrastructure

Tennessee becomes a fusion state

REV and ORNL launch FULCRA

The same week his appointment was announced, REV made news of its own: the FULCRA partnership has just been launched. (How many acronyms can we accumulate this month?) The Fusion Upscaled Leveraged Consortia for Rapid Acceleration is a public-private partnership between Oak Ridge National Laboratory (ORNL) and REV, based in Cambridge, Massachusetts, to create shared fusion test-bed infrastructure at Oak Ridge, intended as a model that other national laboratories can replicate.

The work runs 18 months in two phases. In the first, REV will assess ORNL's fusion capabilities, infrastructure, and programs, covering fusion-enabling technologies, blankets for shielding and fuel breeding, and a neutron source producing fusion-relevant neutron energies. In the second, the partners will develop the technical blueprint, financial framework, and operating model for a pilot "Fulcrum" facility at ORNL: a shared-use test bed where commercial partners can cost-effectively develop and validate critical subsystems such as plasma-facing components, fuel breeding blankets, and power plant-compatible sensors and control systems.

Kyoto Fusioneering brings UNITY-3

In addition to FULCRA, Kyoto Fusioneering is moving its U.S. headquarters to Oak Ridge, where it will build and operate UNITY-3, a breeding blanket test facility funded by the Department of Energy (DOE) and developed with ORNL. The forthcoming device will test a breeding blanket using liquid lithium, along with other candidate breeding blanket materials, and the data from UNITY-3 experiments will be used by Realta Fusion, Thea Energy, Type One Energy and Xcimer Energy to design their future power plants.

Together, these announcements help continue to move fusion breeding blankets from the hand-waving rhetoric of past decades toward an actual engineering program.

ORNL licenses pellet fueling to Type One

Finally, on August 5, at the Nuclear Opportunities Workshop in Knoxville, ORNL licensed a suite of four cryogenic pellet fueling inventions to Type One Energy, covering the design and operation of systems that freeze hydrogen into solid pellets and fire them into a fusion plasma, a more effective way of fueling the plasma core than gas puffing. This development extends an ORNL-Type One relationship that already includes the high-heat-flux test facility with the University of Tennessee and an Innovation Network for Fusion Energy (INFUSE) project.

NRC Agreement State status

"Why Tennessee, besides Oak Ridge?" one might wonder.

The regulatory hook is Agreement State status: in 2023 the Nuclear Regulatory Commission (NRC) decided to regulate fusion machines under its existing byproduct materials program rather than treating them like commercial fission reactors, which pushed licensing authority down to NRC Agreement States (Tennessee being one of them). Tennessee then went first, with Chapter 0400-20-14 taking effect on June 9, 2026 and establishing technology-neutral registration and licensing requirements for fusion machines and fusion-related activities, the first such framework in the country. The rules cut licensing complexity by separating fusion from fission-reactor licensing while still requiring safety, radiation protection, waste management, and emergency preparedness, and there is a National Environmental Policy Act (NEPA) advantage too, since Tennessee is not bound by the NEPA review process an NRC applicant would face.

Korea names fusion a growth engine

On August 12, President Lee Jae Myung named fusion one of seven strategic technologies under Korea's "7 SEED" initiative, alongside small modular fission reactors and renewables. Korea seeks to build a locally developed fusion machine by 2035 via a partnership with the private sector.

Machines

China's 582 tons

Recently, two domestically developed superconducting magnets passed expert acceptance and full-parameter testing at the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in Hefei. Global Times reports that the larger of the two, "a D-shaped toroidal field coil 21 meters long, 12 meters wide, and weighing 582 tons, is the largest fusion magnet ever built, with 1.3 times the volume and three times the stored energy" of its ITER counterpart.

The specifications match the published design of the CFETR prototype coil, which ASIPP describes as 20.5 meters high, 12 meters wide, and weighing 582.4 tonnes.

In early August, a Forbes contributor post reported the coil as BEST hardware, citing the Global Times piece, which makes no such attribution. BEST's own research plan gives its toroidal field system as 16 coils, each weighing 87.2 tons, on page 16, against a total magnetic system mass of roughly 2,000 tons.

MAST Upgrade sets a personal best

Maintaining high plasma pressure without ELMs is essential to achieve relevant fusion scenarios. The United Kingdom's MAST Upgrade tokamak achieved its highest plasma pressure yet while maintaining plasma stability. This is a machine record, not a world one, and the world record of 2.05 atmospheres still belongs to MIT's C-mod from 2016 on its final day of operation.

A separate feat came on the control side: the team steered plasma position using visible-light measurements as a world-first diagnostic. Light emitted by deuterium from the machine's upper and lower divertors allows for real-time measurements of minute positional imbalances.

Fuse claims a neutron record

Fuse announced the highest neutron yield ever publicly documented by a private fusion company: 1.27×10¹² neutrons in a single deuterium-deuterium shot from FAETON-X, its megajoule-class dense plasma focus device. The company says that output range had previously been reached only by U.S. national laboratories. However this claim is an overstatement as first pointed out by Dan Brunner. SHINE has previously already achieved 4.6×10^(13) neutrons per second.

Money

The billion-dollar month

CFS raised another $1 billion at the end of July, for a total of $4 billion, or about 30 percent of the total capital raised by the fusion industry so far. Initially slated to demonstrate net energy by 2025, the SPARC machine is now targeting first plasma and scientific breakeven in 2027. The investors include sovereign wealth funds, infrastructure investors, industrial corporate partners, and pension funds. This should fund the transition from SPARC to ARC.

General Fusion files its first public update

General Fusion, trading on Nasdaq as GFUZ since July and describing itself as the first publicly listed fusion company, issued its first public business update on August 18. The headline physics result is that Lawson Machine 26 (LM26) compressed a plasma with a lithium liner and heated it to about 0.72 keV, roughly 8.4 million degrees Celsius. The near-term objective is 1 keV, then 10 keV, and eventually the Lawson criteria for energy breakeven the machine is named for. The company entered the public markets with roughly $150 million in cash, which it expects to fund the LM26 program through the end of 2028. That is a recent turnaround: in May 2025 the company laid off at least 25 percent of its employees amid funding struggles.

Thea Energy extends its Series B

Stellarator developer Thea Energy closed an extension of its Series B on August 18, amount undisclosed, adding Brevan Howard Macro Venture, Aloniq, ALJ Investments, and Beyond Earth Ventures to its investor list. The extension follows the May $100 million Series B and a July $20 million Advanced Research Projects Agency-Energy (ARPA-E) SCALEUP award to build the first U.S. production lines for modular high-temperature superconducting magnets.

Ideas

MIT prices out fusion

Fusion economics got the academic treatment this month. MIT researchers published a framework for assessing whether a fusion plant can ever pay for itself, co-authored by economist Andrew W. Lo and one Dennis Whyte in the Journal of Fusion Energy. The model spans ten core parameters covering scientific inputs, engineering durability, and capital costs, and defines an Economic Q that must exceed 1.0 for a plant's lifetime revenue to beat its capital and operating costs, a cheeky echo of the physics gain factor the field has chased for decades.

It is worth mentioning that this is one of many recent fusion economics efforts. The Astera Institute previously funded 1 cent fusion energy (1cFE), a study on what it would take to reach a sub-1-cent per kilowatt-hour levelized cost of electricity within a decade.

Hot Takes

TAE goes to the Moon

TAE Technologies signed an agreement on August 5 with Black Moon Energy Corporation, a privately funded lunar-development company, securing an option on future supplies of helium-3, the scarce isotope behind an (almost) aneutronic fuel cycle TAE has pursued alongside its longer-standing hydrogen-boron ambitions. Black Moon plans to fly a robotic delineation mission within five years to characterize lunar helium-3 deposits before any mining begins. TAE frames the deal as fuel-cycle flexibility that its deuterium-tritium-focused competitors cannot match. The fuel would eventually feed Da Vinci, the company's planned 50 MWe plant, which targets operations in 2031, with site selection expected later this year.

The development sounds flashy, but will undoubtedly raise eyebrows: the fuel requires a mine on the Moon, the mine requires a mission that has not flown and the mission belongs to a startup you had likely never heard of before August. To summarize, a supply agreement for fuel that does not exist yet, from a mine that does not exist yet, for a plant that does not exist yet, is ambitious at best and a hype statement to boost valuations at worst.

Yes, this is the same TAE that agreed to a $6 billion all-stock merger with Trump Media and Technology Group, whose flagship asset is a social network, on a stated timeline to break ground on a utility-scale plant in 2026 that The Register called "arguably impossibly ambitious" the week it was announced. And yes, the same TAE that is backed by names like Google and Chevron, and has already raised more than $1 billion. Eight months later there is no groundbreaking, no site, and a closing target that has slipped from mid-2026 to the fourth quarter.

The busiest penny stock in fusion

American Fusion filed 17 patent applications in a single week to reach 100 pending, won approval to move up to the OTCQB Venture Market effective August 21, and said it "intends to evaluate the Nasdaq Capital Market and the Texas Stock Exchange, among other venues", for an eventual uplisting, while pitching Power-as-a-Service electricity to hospitals and AI data centers.

Every substantive claim traces to the company's own press releases, and the company itself says it plans to share video footage and an independent third-party report on test results, which is another way of saying none exists yet.

Closing Thoughts

Fusion funding, whether from sovereign funds or private investors, is continuing to ramp up, and some national policies seem to be warming up toward fusion. The optimism and framing are different from what it was 10 years ago, when the discussion centered more on "will this ever work?" Bad and overabundant acronyms persist, as do slipping deadlines, but the acceleration of progress is undeniable. The funding that fusion should have received at the turn of the millennium is arriving.
