Berkeley

Berkeley occupies a 27-hectare site of Special Scientific Interest on the eastern bank of the River Severn in Gloucestershire and was also home to the Berkeley research laboratories.

Its two reactors were put into safestore in 2010. The site is now focussed on the safe retrieval and packaging of waste held within its subterranean vaults as well as historical waste from the Berkeley research laboratories.

Land previously owned by NDA adjacent to the site has now been delicensed and redeveloped by local college, South Gloucestershire and Stroud (SGS), into the Berkeley Green campus.
