Winfrith was a United Kingdom Atomic Energy Authority site near Winfrith Newburgh in Dorset. It covered an area on Winfrith Heath to the west of the village of Wool between the A352 road and the London Waterloo to Weymouth railway line.

It opened in 1958 and was used for nuclear reactor research and development into the 1990s. The last reactor was shut down in 1995, although decommissioning of the site will not finish till 2021.[1] Winfrith housed nine reactors including the experimental Dragon reactor and a large Steam Generating Heavy Water Reactor (SGHWR) feeding the National Grid from 1968 to 1990. It also housed a used nuclear fuel examination facility, with the associated hot cells.

The Winfrith site was home to a number of experimental reactors including Zenith; Zebra; Juno; Nestor; Dimple; Zeus, and also impact test facilities.

The site is now split between the nuclear licensed site, the extensive Winfrith Technology Centre and the headquarters of the Dorset Police, whose police helicopter is based there.

Ownership of the Winfrith Nuclear site has now passed to the Nuclear Decommissioning Authority (NDA). The site is managed by Research Sites Restoration Limited (RSRL) [2] who are contracted to deliver the site decommissioning programme. RSRL is a subsidiary of Cavendish Nuclear Limited, part of Babcock International Group . The head of site at Winfrith is Michael Dunnett.
