KSTAR fusion reactor sets record with 30-second plasma confinement

A popular design in the pursuit of fusion power is the tokamak and an exciting example of these donut-shaped reactors can be found at the Korea Institute of Fusion Energy, where a new record for maintaining super-hot plasma has reportedly been set.

Nuclear fusion research seeks to form helium atoms under high temperature and pressure, and scientists in China have taken in important step forward

Four ways to fusion: The pros and pitfalls of our nuclear power pursuit

For nearly a century, scientists have been tantalized by the prospect of attaining an inexhaustible source of energy through nuclear fusion. Achieving this goal is not so easy, as it turns out, but that doesn't mean exciting advances aren't being made.

Building to house world's largest tokamak fusion reactor now complete

The structure that will house one of the largest and most ambitious energy experiments in history is now complete, with engineers working on the ITER Tokamak Building swinging their last pylon into place in readiness for the reactor's assembly stage.

The researchers conducted the experiments in the DIII-D tokamak in San Diego

Nuclear fusion plasma could be stabilized against large eruptions – by causing lots of small ones

Nuclear fusion could be an essentially unlimited energy source, but large eruptions in the plasma can damage reactors. But now physicists have found a way to prevent those large eruptions, by triggering lots of small ones through the injection of tiny pellets of beryllium.

Milestone claimed as experimental nuclear reactor reaches temperature of the Sun

A relatively new player on the nuclear fusion scene, a UK company called Tokamak Energy, is claiming a new milestone in the area after heating its ST40 device to 15 million degrees Celsius, similar to temperatures found at the center of the Sun.
