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.
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.
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]
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 Joint European Torus (JET) was a magnetically confined plasma physics experiment, located at Culham Centre for Fusion Energy in Oxfordshire, UK.Based on a tokamak design, the fusion research facility was a joint European project with the main purpose of opening the way to future nuclear fusion grid energy.
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 ]
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 ...
The program is focusing on R&D for pursuing steady-state advanced tokamak operation and supporting design and operation of the ITER experiment now under construction in France. ITER is designed to demonstrate a self-sustained burning plasma that will produce 10 times as much energy from fusion reactions as it requires for heating.
