Tokamak Energy has provided information on a spherical fusion demonstrator it plans to build in the UK by 2026 to demonstrate key technologies and introduce the design of a prototype fusion reactor in the “early 2030s”.

Called the ST80-HTS, the demonstrator will be a high-field spherical tokamak using a high-temperature magnet. Tokamak Energy said it needed to achieve a “sustainable triple output” of plasma density, heat and confinement and to achieve a duration of about 15 minutes. It will replace Tokamak Energy’s ST40 device which achieved plasma temperatures of 100 million C in March.

Construction of the detector is slated to begin in 2024, Tokamak Energy said, however, the decision on where to deploy the device “has not yet been finalized,” the company said. Nuclear News of the World. Tokamak’s current facility in the Oxfordshire district is not big enough, it said, and it is considering options for another site. Tokamak itself will build the device, also producing key elements such as high-temperature superconducting magnets, while working with partners in other areas.

Envisioned to be operational from 2026, the ST80-HTS aims to provide key outputs that will enable the pilot fusion power plant called ST-E1 to operate in the “early 2030s”. The entire roadmap will cost “hundreds of millions of dollars”, Tokamak Energy said.

On 10 October Tokamak Energy signed a framework agreement with the UK Atomic Energy Authority (UKAEA) for closer cooperation on spherical tokamaks. The UKAEA is developing its design with plans to build a prototype known as STEP (Spherical Tokamak for Energy Production) at West Burton.
