The National Ignition Facility (NIF) is a laser-based inertial confinement fusion (ICF) research device, located at Lawrence Livermore National Laboratory in Livermore, California, United States. NIF's mission is to achieve fusion ignition with high energy gain .
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.
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 the target, the Energy Department said.
Spherical Tokamak for Energy Production (STEP) is a spherical tokamak fusion plant concept proposed by the United Kingdom Atomic Energy Authority (UKAEA) and funded by the UK government. [ 1 ] [ 2 ] [ 3 ] The project is a proposed DEMO -class successor device to the ITER tokamak proof-of-concept of a fusion plant, the most advanced tokamak ...
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 ...
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 ...
