The tokamak is one of several types of magnetic confinement devices being developed to produce controlled thermonuclear fusion power. The tokamak concept is currently one of the leading candidates for a practical fusion reactor .
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]
If all goes to plan, Virginia will be the site of the world’s first grid-scale nuclear fusion power plant, ... It is “deep into” building a tokamak able to demonstrate net fusion energy ...
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 ...
As of 2015, tokamak devices are leading candidates for the construction of a viable and practical thermonuclear fusion reactor. [1] These reactors may be used to generate sustainable energy while ensuring a lower environmental impact and a smaller carbon footprint than fossil fuel-based power plants. [2] [3]
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.
The Experimental Advanced Superconducting Tokamak (EAST), also known as HT-7U (Hefei Tokamak 7 Upgrade), is an experimental superconducting tokamak magnetic fusion energy reactor in Hefei, China. Operated by the Hefei Institutes of Physical Science conducting its experiments for the Chinese Academy of Sciences , EAST began its operations in 2006.
The company says its approach to fusion is different from the popular conception, and that it can bring an alternative commercial nuclear fusion power plant to the market by the 2030s.
