Experiments in 2020 and 2021 yielded the world's first burning plasmas, in which most of the plasma heating came from nuclear fusion reactions. [11] This result was followed on August 8, 2021 by the world's first ignited plasma, in which the fusion heating was sufficient to sustain the thermonuclear reaction.
Nuclear fusion, the reaction that powers the sun and other stars, involves smashing two or more atoms together to form a denser one, in a process that releases huge amounts of energy.
Researchers at this Livermore, Calif., facility had spent more than 13 years trying and failing to attain fusion ignition, meaning that the reaction outputs more energy than scientists put into it.
That experiment briefly achieved what's known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to t US scientists repeat fusion ignition ...
In May 2023, United States Department of Energy granted the company additional funding along with seven other US companies via the Milestone-Based Fusion Development Program. [26] In 2024, CFS announced plans to build the world's first grid-scale commercial nuclear fusion power plant at the James River Industrial Center in Chesterfield County ...
Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. [1]
Jennifer Granholm, secretary of the U.S. Department of Energy, says that the U.S. is aiming to create a working fusion reactor by 2035.
