Winfrith
Winfrith Site is located on a 129 hectare site in Dorset. It was constructed in the 1950s to enable vital research into reactor design. The site housed nine experimental reactors at various times with only two remaining today, both of which are being decommissioned.
Fifty hectares of the site was transferred to different ownership in 2003 following its decommissioning and progress since has seen the skyline change dramatically. Ponds have been emptied, bulk asbestos removed and waste sorted.
Winfrith is working towards reaching its interim end state, at which point the land will be returned to heathland with public access.
