The government said that the West Burton coal power station site has been selected as the home for the STEP – Spherical Tokamak for Energy Production – project.
The prototype fusion energy plant is expected to cost upwards of £2bn and could be operational by 2040.
Fusion is based on the same physical reactions that power the sun and stars, combining two hydrogen atoms to release large amounts of energy.
The UK Atomic Energy Authority will invite tenders in December for construction and engineering partner roles on the prototype fusion energy plant.
This appointed team will then work collaboratively with UKAEA, under joint incentivisation mechanisms.
These partners will be core to delivery of the programme, as well as securing market-leading experience and knowledge.
Atkins and energy transition specialists Assystem are working as Tranche 1 engineering delivery partner to develop the concept design for STEP.
Tranche 1 work will conclude in April 2024 when, subject to approval, the engineering and construction partners will develop a fully-formed major programme to deliver a full plant design, a viable supply chain and seek the consents needed for construction.
The construction partner will be tasked with delivering a site development programme, including innovative building designs focused on cost, schedule, safety and sustainability.
