A consortium of British, US and French companies have won an estimated £17 billion contract to run nuclear site Sellafield from the government.
Nuclear Management Partners, led by US company URS Washington Division and including France's Areva as well as London-based Amec, has been selected as preferred bidder for the contract, which is potentially worth £17 billion.
The consortium will operate the reprocessing plant as well as clean up the former nuclear power stations Calder Hall and Windscale in west Cumbria, in addition to the Capenhurst nuclear site and an engineering design centre at Risely in Cheshire.
The contract is expected to offer business to the value of around £1.3 billion per annum and associated dividend opportunities of around £50 million annually and could run for up to 17 years.
Samir Brikho, Amec chief executive said: "Amec is delighted to be part of the consortium successfully selected as preferred bidder for one of the most important public sector contracts in the UK.
"Amec and our consortium members will be contributing world class skills to Sellafield, ensuring that this programme is carried out safely and effectively to the benefit of the taxpayer."
The three groups that lost the bidding were CH2M Hill; Serco with Bechtel and Babcock & Wilcox; and Toshiba together with Texas-based Fluor.
The contract is one of the largest ever given by the government and although it is set to last for 17 years, decommissioning is expected to take 100 years, allowing plenty of scope for renewal.
