Another hurdle in nuclear fusion is controlling the temperature of the reactor itself. For fusion reactions to occur, the reactor temperature must hit 100 million degrees Celsius.

Kairos is trying to reinvent nuclear power. Its molten-salt-cooled reactor could generate safe, reliable, carbon-free electricity that’s potentially as cheap as power generated from natural gas.

Alternative ways of powering, cooling, and constructing reactors could help get more nuclear energy on the grid. This article is from The Spark, MIT Technology Review’s weekly climate newsletter ...

Chemistry Nuclear fusion fuel could be made greener with new chemical process. Lithium-6 is a crucial material for nuclear fusion reactors, but isolating it is challenging – now researchers have ...

Architect’s rendering of the Hermes Low-Power Demonstration Reactor facility. The plant will the first Gen IV reactor to be approved for construction by the US Nuclear Regulatory Commission.

The liquid lithium flows through the hot reactor core and emerges at 2,000° F. The tubes that carry it, made of zirconium-columbium alloy, run at near white heat.

Power plant operators in Switzerland and France idled reactors so that discharged cooling water would not harm wildlife in ...

In testing, the reactor not only dramatically limited the production of chlorine gas, but it achieved a lithium purity rate of 97.5%. “This reactor could represent a major step forward in making ...

Water Cooled Reactors (WCRs) have been the cornerstone of the nuclear industry in the 20th century. Of the currently operating 442 reactors, 96 per cent are water-cooled. Many of these plants were ...
