The Advanced Gas-cooled Reactor (AGR) is a type of nuclear reactor designed and operated in the United Kingdom. These are the second generation of British gas-cooled reactors, using graphite as the neutron moderator and carbon dioxide as coolant. They have been the backbone of the UK's nuclear power generation fleet since the 1980s.
The Central Electricity Generating Board (CEGB) was responsible for electricity generation, transmission and bulk sales in England and Wales from 1958 until privatisation of the electricity industry in the 1990s.
Magnox is a type of nuclear power/production reactor that was designed to run on natural uranium with graphite as the moderator and carbon dioxide gas as the heat exchange coolant. It belongs to the wider class of gas-cooled reactors. The name comes from the magnesium-aluminium alloy used to clad the fuel rods inside the reactor. Like most other "Generation I nuclear reactors", the Magnox was designed with the dual purpose of producing electrical power and plutonium-239 for the nascent nuclear weapons programme in Britain. The name refers specifically to the United Kingdom design but is sometimes used generically to refer to any similar reactor.
British Nuclear Fuels Limited (BNFL) was a nuclear energy and fuels company owned by the UK Government. It was a manufacturer of nuclear fuel, ran reactors, generated and sold electricity, reprocessed and managed spent fuel, and decommissioned nuclear plants and other similar facilities.
The Dungeness nuclear power stations are a pair of non-operational nuclear power stations located on the Dungeness headland in the south of Kent, England.
British Energy was the UK's largest electricity generation company by volume, before being taken over by Électricité de France (EDF) in 2009. British Energy operated eight former UK state-owned nuclear power stations and one coal-fired power station.
Chapelcross nuclear power station is a decommissioned and partly demolished Magnox nuclear power station near Annan in Dumfries and Galloway in southwest Scotland, which was in operation from 1959 to 2004. It was the sister plant to the Calder Hall plant in Cumbria, England; both were commissioned and originally operated by the United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the UK's nuclear weapons programme, but they also generated electrical power for the National Grid.
National Power was an energy company based in the United Kingdom.
Hartlepool nuclear power station is a nuclear power station situated on the northern bank of the mouth of the River Tees, 2.5 mi south of Hartlepool in County Durham, North East England. The station has a net electrical output of 1,185 megawatts, which is 2% of Great Britain's peak electricity demand of 60 GW. Electricity is produced through the use of two advanced gas-cooled reactors (AGR). Hartlepool was only the third nuclear power station in the United Kingdom to use AGR technology. It was also the first nuclear power station to be built close to a major urban area.
The Nuclear Liabilities Fund is a fund of the UK Government to provide arrangements for funding certain long-term costs for the decommissioning of eight nuclear power stations formerly owned by British Energy, now EDF Energy. Responsibility for the fund within government lies with the Shareholder Executive, on behalf of the Department for Business, Energy and Industrial Strategy.
Nuclear power in the United Kingdom generated 16.1% of the country's electricity in 2020. As of August 2022, the UK has 9 operational nuclear reactors at five locations, producing 5.9 GWe. It also has nuclear reprocessing plants at Sellafield and the Tails Management Facility (TMF) operated by Urenco in Capenhurst.
Heysham nuclear power station is operated by EDF Energy in Heysham, Lancashire, England. The site is divided into two separately-managed nuclear power stations, Heysham 1 and Heysham 2, both with two reactors of the advanced gas-cooled reactor (AGR) type.
Bradwell nuclear power station is a decommissioned Magnox-design nuclear power station located on the Dengie peninsula at the mouth of the River Blackwater, Essex. In 2019, it was the first nuclear power station in the UK to be placed into long-term decommissioned management. As of 2016, China General Nuclear Power Group and China National Nuclear Corporation are considering Bradwell for the site of a new nuclear power station, named Bradwell B.
Scottish Nuclear was formed as a precursor to the privatisation of the electricity supply industry in Scotland on 1 April 1990. A purpose-built headquarters was built in 1992 in the new town of East Kilbride.
Hinkley Point B nuclear power station is a nuclear power station near Bridgwater, Somerset, on the Bristol Channel coast of south west England. It was the first commercial Advanced Gas Cooled reactor to generate power to the National Grid in 1976 and shares its design with sister station Hunterston B nuclear power station. It ceased operations permanently on 1 August 2022.
Hinkley Point A nuclear power station is a Magnox nuclear power station undergoing decommissioning. It is located on a 19.4-hectare (48-acre) site in Somerset on the Bristol Channel coast, 5 miles (8 km) west of the River Parrett estuary. The ongoing decommissioning process is being managed by Nuclear Decommissioning Authority licensee Magnox Ltd.
The Sizewell nuclear site consists of two nuclear power stations, one of which is still operational, located near the small fishing village of Sizewell in Suffolk, England. Sizewell A, with two Magnox reactors, is now in the process of being decommissioned. Sizewell B has a single pressurised water reactor (PWR) and is the UK's newest nuclear power station. A third power station, to consist of twin EPR reactors, is planned to be built as Sizewell C.
Oldbury nuclear power station is a Magnox nuclear power station undergoing decommissioning. It is located on the south bank of the River Severn close to the village of Oldbury-on-Severn in South Gloucestershire, England. The ongoing decommissioning process is managed by Magnox Ltd, a subsidiary of the Nuclear Decommissioning Authority (NDA).
Hunterston A nuclear power station is a decommissioned Magnox nuclear power station located at Hunterston in Ayrshire, Scotland, adjacent to Hunterston B. The ongoing decommissioning process is being managed by Nuclear Decommissioning Authority (NDA) subsidiary Magnox Ltd.
Magnox Ltd is a nuclear decommissioning Site Licence Company (SLC) under the Nuclear Decommissioning Authority (NDA), a government body set up specifically to deal with the nuclear legacy under the Energy Act 2004. In September 2019, it became a direct subsidiary of the NDA.
