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.
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]
A December 13, 2022 video announcement of the first controlled fusion experiment in history to achieve fusion ignition, via the YouTube page of the Lawrence Livermore National Laboratory Principal designer Annie Kritcher speaks at the December 13, 2022 press conference announcing breakeven ignition. The NIF became the first fusion experiment to ...
Building, owning and operating a power plant to plug fusion power into the grid is its “next act,” Mumgaard said. The startup looked at more than 100 locations around the world for the power ...
U.S. scientists have achieved “ignition” — a fusion reaction that produced more energy than it took to create — a critical milestone for nuclear fusion and a step forward in the pursuit of ...
This kind of fusion reactor would consist of two parts: Targets which can be small capsules (<7 millimeter diameter) that contain fusion fuel. Although many kinds of targets have been tested including: cylinders, shells coated with nanotubes, solid blocks, hohlraum, glass shells filled with fusion fuel, cryogenically frozen targets, plastic shells, foam shells and materials suspended on spider ...
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.
