The value of the work covered is worth £1.3 billion in its first year and over the full lifetime of the contract approximately £22 billion.
Shares in Sellafield have been transferred from British Nuclear Fuels to NMP, which is a consortium of URS’ Washington Division, Amec and Areva.
NMP will own the shares in Sellafield for up to 17 years, the potential length of new and updated contracts between the NDA, NMP and Sellafield.
Today’s news marks the completion of a two-year process in which four international consortia competed for the contract.
Chairman of the NDA Stephen Henwood said: “This signals a new relationship between the public and private sector, based on partnership delivery, to tackle the most significant nuclear decommissioning, clean-up and socio-economic challenges at the sites managed and operated by Sellafield.”
