A consortium including Amec has won the £6.75bn five-year contract to clean up the Sellafield nuclear power plant.

Amec will work alongside French company Areva  and US contractor Washington International on the deal worth around £1.3bn a year plus fees of another £50m a year.

Further extensions could increase the length of the contract to 17 years.

Apart from the reprocessing and waste storage facilities at Sellafield, the trio will work on former nuclear power stations Calder Hall and Windscale, as well as the Capenhurst nuclear site and an engineering design centre at Risely in Cheshire.
