About NRS

Berkeley site

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.

Bradwell site

Bradwell was built on the edge of a former World War II airfield, one and a half miles from the Essex coastline.

Chapelcross site

Chapelcross was Scotland’s first commercial nuclear power station and was built on the 92-hectare site of a World War II training airfield in Dumfries and Galloway.

Dounreay division

Dounreay was the centre of the UK’s research programme into nuclear fast breeder reactors for four decades, and is now a site of decommissioning, major construction and waste management as it dismantles one of the most complex and hazardous legacies of the 20th century.

Dungeness A site

Dungeness A occupies about a quarter of a 91-hectare civil nuclear site on the Kent coast in an area of Special Scientific Interest. It is a very exposed location on a shingle beach on the edge of the English Channel.

Harwell site

Harwell is located on a 91 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.

Hinkley Point A site

Hinkley Point A is located on 19 hectares on the Somerset coast. Low carbon electricity generation ended in 2000 following 35 years of safe operation. Decommissioning began in 2005 when defueling was completed.

Hunterston A site

Hunterston A is located on 65-hectare site on a promontory off the Ayrshire coastline, 30 miles south-west of Glasgow. Low carbon electricity generation ended in 1990 followed by defueling in 1995.

Hunterston B site

Oldbury site

Oldbury occupies 39 hectares on the bank of the River Severn in South Gloucestershire. The site moved into its decommissioning phase following the completion of defueling in 2016.

Sizewell A site

Sizewell A is located near Leiston in Suffolk and is a twin reactor site. The site became fully operational in 1966 and shut down on 31 December 2006 after 40 years of low carbon electricity generation. Decommissioning commenced in 2014 when the defueling phase completed.

Trawsfynydd site

Trawsfynydd is located on a 15.4 hectare site in Snowdonia National Park, North Wales, Trawsfynydd was the first inland civil nuclear station and drew its cooling water from Llyn (lake) Trawsfynydd.

Winfrith site

Winfrith is located on a 84 hectare site in Dorset. It was constructed in the 1950s to enable vital research into reactor design.

Wylfa site

Wylfa is located on a 50 hectare site on the north coast of Anglesey. It was the biggest and last of the first generation Magnox gas-cooled nuclear reactors to be built. Electricity generation ceased in 2015 bringing a safe conclusion to Magnox reactor generation in the UK.
