China’s "artificial sun" EAST fusion reactor smashed the previous record for sustained plasma, advancing nuclear fusion research.

On May 22, the latest experimental campaign concluded at the world's most powerful nuclear fusion device of the stellarator type. Through collaboration between researchers from Europe and the U.S., Wendelstein 7-X achieved, among other milestones, a world record in a key parameter of fusion physics: the triple product. This value now exceeds previous tokamak records for long plasma durations.

The former dean of MIT's plasma fusion dept—which is intimately tied to the privately funded Commonwealth Fusion Systems, current darling of the market—gives an insider’s take on what is happening out...

UPDATED: STEP sucked up £220 million in 2022, and it's still not apparent what that accomplished

Inertial confinement reactors, stellarators and tokamaks each have pros and cons

Temperatures of more than 10,000°C and a hail of charged particles from the fusion fuel (plasma): These are extreme conditions that the exhaust wall (divertor) of future fusion power plants will need to withstand. It makes handling the exhaust stream one of the main challenges to realizing clean, safe and affordable commercial fusion power plants.

Tokamaks are machines that are meant to hold and harness the power of the sun. These fusion machines use powerful magnets to contain a plasma hotter than the sun's core and push the plasma's atoms to fuse and release energy. If tokamaks can operate safely and efficiently, the machines could one day provide clean and limitless fusion energy.

Hexium has emerged from stealth with $8 million in seed funding.

Commonwealth Fusion Systems (CFS), a Massachusetts-based company, has initiated the process of obtaining local zoning approval for a substantial nuclear fusion energy project in Chesterfield, Virginia. The company recently submitted a conditional-use permit application to Chesterfield County for the planned power plant, slated for a 94-acre site located at 1201 Battery Brooke Parkway. The Chesterfield project aims to be the first commercial nuclear fusion power plant globally. CFS anticipates construction to begin in the late 2020s, with the plant expected to be operational in the early 2030s. The facility, named ARC, is projected to generate 400 megawatts of electricity, enough to power approximately 150,000 homes. Dominion Energy currently owns the land, and CFS has secured an option-to-lease agreement for the site. The project is expected to create around 150 full-time jobs. CFS, which identifies as the world’s largest private fusion company, was established in 2018, originating from MIT as a business venture. The company has amassed over $2 billion in investment and employs more than 1,000 people. The Chesterfield project was publicly announced late last year, with Governor Glenn Youngkin describing it as a “multi-billion-dollar” undertaking. The zoning application will be reviewed by the Planning Commission before a final decision by the Board of Supervisors. In addition to local approval, the project requires state and federal permits. The SPARC, CFS’s prototype fusion machine, is currently under construction at the company’s campus in Devens, Massachusetts, with a 75-ton stainless steel base recently installed. SPARC utilizes powerful magnets to confine a hot plasma, enabling nuclear fusion to occur. Recent reports indicate CFS is in the process of raising over $1 billion in capital, with funds specifically allocated to the Chesterfield project. GreeneHurlocker's Ann Neil Cosby is representing CFS in the zoning process, and Timmons Group is serving as the project's engineer.
