A team of Chinese researchers has conducted an experiment that is nicknamed the “Chinese artificial sun” using the Experimental Advanced Superconducting Tokamak (EAST) fusion device. The EAST device has been conducting a four-month-long experiment with the goal of seeing how hot the electron temperature inside the fusion device could be. The scientists were able to achieve an electron temperature in the core plasma of over 100 million degrees.

Nuclear engine (aka YaEDU):
A key component of Russia’s future nuclear space propulsion system, which may revolutionize long-range exploration of the solar system, has been successfully tested, RIA Novosti reported.
Since at least 2009, Russian space and atomic engineers have been developing a special space propulsion system, which uses a 1 megawatt nuclear fusion reactor as source of energy. According to a work competition report, published on a website tracing public spending in Russia and reviewed by the news agency, one of the crucial elements of the system, which is responsible for cooling down the reactor, has been successfully tested.
The nuclear engine, which is known by its abbreviation YaEDU (Nuclear Propulsion and Power Engine System) consists of a small fast-neutron nuclear reactor, an electricity generator fed by the reactor’s heat and space thrusters powered by the generator.
Commonwealth Fusion Systems will use new superconducting materials to make far stronger magnets for a smaller Tokamak fusion system. The planned fusion experiment, called Sparc, is set to be far smaller – about 1/65th of the volume – than that of the International Thermonuclear Experimental Reactor project, an international collaboration.

Transatomic Power, an MIT spinout that drew wide attention and millions in funding, is shutting down almost two years after the firm backtracked on bold claims for its design of a molten-salt reactor.
High hopes: The company, founded in 2011, plans to announce later today that it’s winding down.
Transatomic had claimed its technology could generate electricity 75 times more efficiently than conventional light-water reactors, and run on their spent nuclear fuel. But in a white paper published in late 2016, it backed off the latter claim entirely and revised the 75 times figure to “more than twice,” a development first reported by MIT Technology Review.
