a seven-tenths-scale prototype of a commercial nuclear-fusion reactor. The firm picked Culham because it is the site of JET, the Joint European Torus, an experimental fusion reactor opened in 1983 ...

The company announced yesterday that it had created plasma inside its prototype reactor – a major milestone in proving its technology. This proves General Fusion's Lawson Machine 26 (LM26 ...

a superheated fourth state of matter required for fusion, inside a prototype reactor. The milestone marks the beginning of a 93-week quest to prove that the outfit’s steampunk approach to fusion ...

ITER, a $28 billion fusion reactor in France, has finally had its last magnetic coil installed. But the reactor itself won't fire up fully until 2039 at the earliest. When you purchase through ...

On Tuesday, the people managing the ITER experimental fusion reactor announced that a combination of delays and altered priorities meant that its first-of-its-kind hardware wouldn't see plasma ...

Japan has taken a major step toward revolutionizing energy production with the launch of the JT-60SA reactor, the world’s largest experimental nuclear fusion reactor. This project represents a ...

If we want to rely on nuclear fusion to power the world's homes, the first step is making reactors that can run as hot and as long as possible. Now, China's 'artificial sun' reactor ...

The International Thermonuclear Experimental Reactor, or ITER, needs to come up with an updated pathway toward achieving fusion by 2024, the project’s supervisors said Thursday, giving ...

The biggest experimental nuclear fusion reactor in operation was inaugurated north of Tokyo today, as scientists continue to plug away at making nuclear fusion a viable source of the world’s energy.

The world’s largest and most powerful superconducting electromagnet is ready to become the pulsing “heart” inside of a massive tokamak nuclear fusion reactor. Developed over 40 years in ...

A way of controlling the size of instabilities in the plasma of fusion reactors has been discovered by an international team of researchers. Large instabilities can damage a reactor, while small ...
