Harwell
Harwell Site is located on a 102 hectare site in Oxfordshire and is the birthplace of the UK nuclear industry. Originally an RAF station, it became Britain's Atomic Energy Research Establishment in 1946. There were 14 experimental reactors on the site, with three remaining today.
Significant progress is being made in decommissioning the site, with waste being treated, sorted and disposed of and the construction of a new intermediate level waste store.
