Three companies including Atkins have won deals to support the design and construction of the £15bn Wylfa Newydd nuclear plant in north Wales.
Atkins, KBR and Wood are the latest companies to be chosen as partners on the proposed Anglesey plant, for which they will support the delivery of the nuclear island.
Atkins, which was bought by SNC Lavalin last year, will assist the civil engineering design for the island, KBR will work on project controls, and Wood will support the island’s architectural engineering.
All you need to know: what are the plans, who’s on site and what happens next?
The three firms were picked by Hitachi, which will deliver the nuclear island. The plant’s construction is being managed by developer Horizon Nuclear Power, which is owned by Hitachi.
The contracts are the latest construction deals to be let on the Anglesey project, with Bechtel signing the deal to be the project management contractor for the scheme in August.
Wylfa, construction of which could begin as early as 2020, will have a capacity of 2,700 MW – enough to power five million homes. Its construction is expected to create 8,500 jobs.
The government confirmed in June that it had begun talks with Hitachi over a final funding deal that would kick-start construction on the scheme.
As part of the announcement, business secretary Greg Clark said a deal could see the government invest public money to fund construction.
The Department for Business, Energy and Industrial Strategy stressed at the time that a decision had not been made on the scheme, and that it still needed to carry out value-for-money checks, as well as a due diligence review of the developer and state aid requirements.
Last December Hitachi secured the green light for its ABWR reactor design after passing the Office of Nuclear Regulation’s generic design assessment, a process which took more than four years.
Commenting on the contracts, Hitachi Nuclear Energy Europe project director Mr Eric Chassard said: “Wood has been involved in every nuclear new build in UK history.
“KBR and Atkins are also world leaders in their fields – with clear and proven experience on projects of this scale and complexity.
“The pedigree, expertise and detailed knowledge of all three partners are second to none.”
