Britain's Tokamak Energy has been named magnet systems partner for the UK's STEP Fusion programme, while France's Dassault Systèmes has been contracted to expand STEP's product lifecycle management capability.

In October 2022, the West Burton coal-fired power plant site in Nottinghamshire, England, was selected to host the UK's Spherical Tokamak for Energy Production (STEP). The demonstration plant is due to begin operating by 2040. The technical objectives of STEP are: to deliver predictable net electricity greater than 100 MW; to innovate to exploit fusion energy beyond electricity production; to ensure tritium self-sufficiency; to qualify materials and components under appropriate fusion conditions; and to develop a viable path to affordable lifecycle costs. As well as the STEP fusion facility, a skills centre and a business park are planned.

UK Fusion Energy Ltd (UKFE) - a subsidiary of the United Kingdom Atomic Energy Authority which will build the UK's prototype fusion power plant – has now awarded a GBP70 million (USD95 million) contract covering the period up to March 2029 to Tokamak Energy after it was identified as the leading UK-based manufacturing expert with the specialist capabilities to deliver the plant's magnets.
