Harwell Science and Innovation Campus

A large part of the site was formerly the main research establishment of the United Kingdom Atomic Energy Authority, but it has seen a transition to its new role as a science and business park as the nuclear facilities have been decommissioned.

Over 6,000 people work on the campus in some 240 organisations representing a multidisciplinary range of advanced scientific and technological disciplines.

The campus is owned by the UKAEA, the Science and Technology Facilities Council and Public Health England.

The northern part of the Campus was formerly the Atomic Energy Research Establishment, which was created after the Second World War on the site of RAF Harwell.

As parts of the site are decommissioned, they are delicensed and dedesignated and no longer secured hence the area "inside the fence" is gradually shrinking.

[7] In August 2006 the government announced an investment of £26.4 million to construct new research facilities on the campus[8] and the creation of a joint venture partnership.
