With the International Thermonuclear Experimental Reactor (ITER) as the most visible part of nuclear fusion research, it is perhaps little wonder that the recent string of delays and budget ...

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 ...

Last summer, when word came down that ITER, the international thermonuclear reactor, would be built in France, fusion scientists breathed a collected sigh of relief. The start of construction of ...

Such issues have led to a resurgence of interest in a third nuclear option, which combines aspects of both technologies in the form of the fusion–fission hybrid reactor. The fusion–fission ...

Japan’s JT-60SA fusion reactor project announced first plasma in October of this year to denote the successful upgrades to what is now the world’s largest operational, superconducting tokamak ...

A world record for nuclear fusion has been smashed after an ‘artificial sun’ reactor was able to maintain a plasma for more ...

Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas. It also produces and consumes tritium within the plant in a ...

But now, with net-positive fusion power no longer the stuff of science fiction, a fresh crop of startups have been founded on more mundane questions: Can reactors be built for less money?

SAN FRANCISCO--A start-up that a Nobel laureate co-founded plans to commercialize a nuclear fusion reactor using laser technology by around 2030. Shuji Nakamura, co-recipient of the 2014 Nobel ...

Nuclear fusion reactors, if and when they become practical, will need a steady supply of fuel. The source of that fuel is the uncommon lithium isotope lithium-6. And the established process to ...
