Winfrith

Winfrith was established by the UKAEA in 1958 as an experimental reactor research and development site. During its history, eight research reactors of various types have operated on the site. Winfrith also had a number of other facilities including fuel manufacture and examination, plutonium laboratories, nuclear waste treatment and storage and radioactive laboratories.

The last reactor closed in 1995. Five of the reactors have been removed from the site; the three remaining have had fuel removed and are in various stages of decommissioning. Parts of the Winfrith site have been delicensed and it is expected that the remaining decommissioning will be completed by 2020.
