The UK government has been trying for some time to incorporate private-sector practices into government-run research centres. AWE Management replaces Hunting-BRAE, who were awarded a seven-year contract to manage the UK nuclear programme in 1993. BNFL is expected to manage waste, decommissioning and "legacy clean-up" operations, Lockheed will control weapons and technology, while Serco will run the administration of the facility. The group is already considering closing AWE's Burghfield site in Berkshire, and in the next four years all of AWE's services are expected to move to Aldermaston, AWE's main research facility. The number of staff is also predicted to drop to 3000 because of rationalisation and a reduction in the number of UK nuclear warheads.
