As of 2023, the Wendelstein 7-X reactor is the world's largest stellarator device. [3] After two successful operation phases ending in October 2018, the reactor was taken offline for upgrades. [4] [5] The upgrade completed in 2022. New fusion experiments in February 2023 demonstrated longer confinement and increased power. [6]
Artist's concept of DEMO connected to the power grid. DEMO, or a demonstration power plant (often stylized as DEMOnstration power plant), refers to a proposed class of nuclear fusion experimental reactors that are intended to demonstrate the net production of electric power from nuclear fusion.
Researchers meet annually at the US-Japan Workshop on Inertial Electrostatic Confinement Fusion. The following is a list of machines that were actually built. Tokyo Institute of Technology has four IEC devices of different shapes: a spherical machine, a cylindrical device, a co-axial double cylinder and a magnetically assisted device.
Fusion reactors are not subject to catastrophic meltdown. [122] It requires precise and controlled temperature, pressure and magnetic field parameters to produce net energy, and any damage or loss of required control would rapidly quench the reaction. [123] Fusion reactors operate with seconds or even microseconds worth of fuel at any moment.
The particle densities tend to be in the range of 10 18 to 10 22 m −3 and the linear dimensions in the range of 0.1 to 10 m. The particle and energy confinement times may range from under a millisecond to over a second, but the configuration itself is often maintained through input of particles, energy, and current for times that are hundreds ...
The Lockheed Martin Compact Fusion Reactor (CFR) was a fusion power project at Lockheed Martin’s Skunk Works. [1] Its high-beta configuration, which implies that the ratio of plasma pressure to magnetic pressure is greater than or equal to 1 (compared to tokamak designs' 0.05), allows a compact design and expedited development.
ITER (initially the International Thermonuclear Experimental Reactor, iter meaning "the way" or "the path" in Latin [2] [3] [4]) is an international nuclear fusion research and engineering megaproject aimed at creating energy through a fusion process similar to that of the Sun.
A technician looks through the center of the NRL Linus-0 reactor. The Linus program [a] was an experimental fusion power project developed by the United States Naval Research Laboratory (NRL) starting in 1971. [2] The goal of the project was to produce a controlled fusion reaction by compressing plasma inside a metal liner.
