Leadership of the UK's STEP (Spherical Tokamak for Energy Production) programme has transitioned to UK Industrial Fusion Solutions Ltd, a wholly-owned subsidiary of the UK Atomic Energy Authority.
The establishment of UK Industrial Fusion Solutions Ltd (UKIFS) as a new delivery body for the UK's fusion programme was announced in February 2023 by then Science Minister George Freeman.
UKIFS will lead a public-private partnership that will design, build and operate the STEP prototype fusion plant at the West Burton power plant site in Nottinghamshire, England. The West Burton site was selected to host STEP in October 2022.
The UK Atomic Energy Authority (UKAEA) - which carries out fusion energy research on behalf of the government - said it will continue to be STEP's fusion partner, working alongside two industry partners โ one in engineering and one in construction โ to spearhead the development of a UK-led fusion industry.
"A major procurement exercise is currently under way to select STEP's strategic, long-term industry partners, with the shortlist expected to be announced by the end of the year," the UKAEA said.
"The launch of UK Industrial Fusion Solutions demonstrates significant progress and commitment to developing fusion as a viable clean energy source, and also to creating a UK-led fusion industry," said Paul Methven, CEO of UKIFS and Senior Responsible Owner for STEP. "STEP is a national endeavour with global impact, and we will continue to work closely with public and private sector partners to ensure the UK remains at the forefront of a revolutionary sustainable new energy source that will drive economic growth."
Ian Chapman, CEO of UKAEA, said: "UKIFS brings together an experienced team dedicated to translating decades of fusion research into a functioning prototype plant that will be capable of supplying low-carbon, safe, and sustainable energy to the grid. UKIFS will integrate partners in a national endeavour to build STEP as well as focussing on delivering enormous social and economic benefits to the UK, especially for the East Midlands region where the plant will be built."
The aim for the first phase of work on STEP is to produce a 'concept design' by the end of this year. The UK government is providing GBP220 million (USD285 million) of funding for this part. The next phase of work will include detailed engineering design, while all relevant permissions and consents to build the prototype are sought. The final phase is construction, with operations targeted to begin around 2040. The aim is to have a fully evolved design and approval to build by 2032, enabling construction to begin. 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.
