Cavendish Dounreay Partnership
In October 2013 it changed its name to Cavendish Dounreay Partnership, following the decision of Babcock International Group, which has a 50 per cent stake in the parent body organisation, to rebrand its civil nuclear business unit as Cavendish Nuclear.
In April 2012 the Babcock Dounreay Partnership was selected as preferred bidder and awarded a £1.6bn contract by the Nuclear Decommissioning Authority for the management and decommissioning of the Dounreay nuclear site in Caithness, Scotland.
Decommissioning of the site is anticipated by 2022-25, 'shaving 14 years and £1 billion off previous forecasts' according to the company.
