# Scientists Just Fired Up an Experimental Fusion Reactor

## First Plasma

A team of scientists at the Culham Centre for Fusion Energy (CCFE) in the UK [claim to have achieved first plasma](<https://phys.org/news/2020-11-team-plasma-mast-ready-super-x.html>) on an upgraded, experimental fusion reactor.

Generating electricity using fusion, which means harnessing the power of atoms fusing together rather than breaking them up, is still many years — if not decades — out. But the team is hoping their new design could solve a big problem: hot plasma, with temperatures of over 15 million degrees Celsius, which typically deals great damage to the reactor itself.

## Diverting Heat

Fusion energy has a key advantage over conventional nuclear energy: it doesn't create radioactive waste that's expensive and difficult to dispose of. But the process of fusion using plasma builds up massive amounts of energy in the form of heat, so the team at CCFE came up with a "divertor" that acts as an exhaust system for their reactor.

The team's "Super-X divertor" was designed from the ground up to "reduce heat and power loads from particles leaving the plasma, which should mean divertor components will last much longer," according to [a press release](<https://ccfe.ukaea.uk/research/mast-upgrade/>).

## Spinning Right Round

The exhaust was designed with the UK facility's almost perfectly spherical tokamak — the reactor core that holds the plasma — in mind.

Conventionally, tokamaks have been built in the shape of a donut, formally called a torus. The team is hoping a round design will allow for much smaller and considerably cheaper fusion plant designs in the future.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
