Confirmation of the deal came yesterday as the UK Government finally signed its £18bn contract with France and China to build the nuclear power station, giving the final go-ahead for construction at the site in Somerset.

Around £3bn-worth of contracts with construction and engineering firms have already been committed to deliver the nuclear plant.

UK-based businesses will benefit from more than 60% of the £18bn value of the project and 26,000 jobs and apprenticeships will be created.

KBR’s reimbursable rates contract will cover site operations management, contract management, and materials tracking.

To support the construction work at the West Somerset site, substantial activity will also take place at its project offices in Paris, Bristol and Bridgwater.

KBR will provide support for the equipment supply chain, involving over 100 international suppliers and contractors.
