If all goes to plan, Virginia will be the site of the world’s first grid-scale nuclear fusion power plant, able to harness this futuristic clean power and generate electricity from it by the ...
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 ]
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.
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 ...
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 the target, the Energy Department said.
