The Atomic Energy Authority has announced that it is speeding up the decommissioning of the former Harwell Laboratory site.

Site manager John Wilkins said the aim was to return large areas of the 750-acre Harwell science and business centre to a safe "passive" state by 2015, five years earlier than previously envisaged.

The work programme, which includes decommissioning the Gleep test reactor and other nuclear facilities, will be submitted to the Department of Trade and Industry ready for the proposed Nuclear Decommissioning Authority, which is being set up by the Government.

The plan gives details of the decommissioning programme for the site over the next two years, such as cleaning up three acres of chemical waste storage pits.

Dr Wilkins said: "Nobody in western Europe has more experience of managing the safe decommissioning of nuclear sites than the UKAEA.

"This is underlined in the commitments we have made to the Government to accelerate the decommissioning of Harwell in a way that continues to be safe."

Over the next two years, the Gleep reactor will be removed, paving the way for clearance of the eastern end of the site.

The UKAEA is keen to attract companies as part of a plan to turn the site into an international business park.
