Cutaway diagram of the International Thermonuclear Experimental Reactor (ITER) the largest tokamak in the world, which began construction in 2013 and is projected to begin full operation in 2035. It is intended as a demonstration that a practical fusion reactor is possible, and will produce 500 megawatts of power.
The private U.S. nuclear fusion company Helion Energy has signed a deal with Microsoft to provide electricity in about five years, marking the first such agreement for fusion power. Helion's plant, expected to be online by 2028, aims to generate 50 megawatts or more of power. The company plans to use helium-3, a rare gas as a fuel source. [28]
A spherical tokamak is a type of fusion power device based on the tokamak principle. It is notable for its very narrow profile, or aspect ratio. A traditional tokamak has a toroidal confinement area that gives it an overall shape similar to a donut, complete with a large hole in the middle. The spherical tokamak reduces the size of the hole as ...
The T-15 (or Tokamak-15) is a Russian (previously Soviet) nuclear fusion research reactor located at the Kurchatov Institute, which is based on the (Soviet-invented) tokamak design. [2] It was the first industrial prototype fusion reactor to use superconducting magnets to control the plasma . [ 3 ]
SPARC plans to verify the technology and physics required to build a power plant based on the ARC fusion power plant concept. [1] SPARC is designed to achieve this with margin in excess of breakeven and may be capable of achieving up to 140 MW of fusion power for 10 second bursts despite its relatively compact size. [2] [1]
As of 2023 the device is known as JT-60SA and is the largest operational superconducting tokamak in the world, [1] built and operated jointly by the European Union and Japan in Naka, Ibaraki Prefecture. [2] [3] SA stands for super advanced tokamak, including a D-shaped plasma cross-section, superconducting coils, and active feedback control.
Nuclear fusion is a blanket term that covers any reaction where, literally, the nucleuses of two different atoms are fused. It’s that simple. That’s as opposed to nuclear fission , where one ...
HT-7, or Hefei Tokamak-7, is an experimental superconducting tokamak nuclear fusion reactor built in Hefei, China, to investigate the process of developing fusion power.The HT-7 was developed with the assistance of Russia, and was based on the earlier T-7 tokamak reactor.
