Winfrith Technology Centre - Geograph
Winfrith Atomic Energy Establishment, or AEE 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 South West Main Line. Winfrith was set up in order to test a variety of new nuclear reactor designs with the intention of selecting a new design for power generation and other tasks. The main design built at the site was the demonstration steam-generating heavy water reactor (SGHWR) providing power to the National Grid. A number of smaller designs were also constructed at the site. The site officially opened with the ZENITH reactor in 1960. SGHWR opened in 1967 and was shut down in 1990. All of the reactors have been shut down and are in various stages of removal. The site is now being re-used for other purposes while decommissioning continues. Nuclear research The initial steps that led to the formation of Winfrith began with the creation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UKAEA
The United Kingdom Atomic Energy Authority is a UK government research organisation responsible for the development of fusion energy. It is an executive non-departmental public body of the Department for Business, Energy and Industrial Strategy (BEIS). The authority focuses on United Kingdom and European fusion energy research programmes at Culham in Oxfordshire, including the world's most powerful operating fusion device, the Joint European Torus (JET).

On its formation in 1954, the authority was responsible for the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Land
Common land is land owned by a person or collectively by a number of persons, over which other persons have certain common rights, such as to allow their livestock to graze upon it, to collect Wood fuel, wood, or to cut turf for fuel. A person who has a right in, or over, common land jointly with another or others is usually called a commoner. In the New Forest, the New Forest Commoner is recognised as a minority cultural identity as well as an agricultural vocation, and members of this community are referred to as Commoners. In Great Britain, common land or former common land is usually referred to as a common; for instance, Clapham Common and Mungrisdale Common. Due to enclosure, the extent of common land is now much reduced from the millions of acres that existed until the 17th century, but a considerable amount of common land still exists, particularly in upland areas. There are over 8,000 registered commons in England alone. Origins Originally in medieval England the co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CANDU Reactor
The CANDU (Canada Deuterium Uranium) is a Canadian pressurized heavy-water reactor design used to generate electric power. The acronym refers to its deuterium oxide ( heavy water) moderator and its use of (originally, natural) uranium fuel. CANDU reactors were first developed in the late 1950s and 1960s by a partnership between Atomic Energy of Canada Limited (AECL), the Hydro-Electric Power Commission of Ontario, Canadian General Electric, and other companies. There have been two major types of CANDU reactors, the original design of around 500 MWe that was intended to be used in multi-reactor installations in large plants, and the rationalized CANDU 6 in the 600 MWe class that is designed to be used in single stand-alone units or in small multi-unit plants. CANDU 6 units were built in Quebec and New Brunswick, as well as Pakistan, Argentina, South Korea, Romania, and China. A single example of a non-CANDU 6 design was sold to India. The multi-unit design was used o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-cooled Reactor
A gas-cooled reactor (GCR) is a nuclear reactor that uses graphite as a neutron moderator and a gas (carbon dioxide or helium in extant designs) as coolant. Although there are many other types of reactor cooled by gas, the terms ''GCR'' and to a lesser extent ''gas cooled reactor'' are particularly used to refer to this type of reactor. The GCR was able to use natural uranium as fuel, enabling the countries that developed them to fabricate their own fuel without relying on other countries for supplies of enriched uranium, which was at the time of their development in the 1950s only available from the United States or the Soviet Union. The Canadian CANDU reactor, using heavy water as a moderator, was designed with the same goal of using natural uranium fuel for similar reasons. Design considerations Historically thermal spectrum graphite moderated gas cooled reactors mostly competed with light water reactors, ultimately losing out to them after having seen some deployment in Brit ...

Dragon Reactor
DRAGON Reactor Experiment (DRE) was an experimental high temperature gas-cooled reactor at Winfrith in Dorset, England, an experimental reactor of the Organisation for Economic Co-operation and Development (O.E.C.D) High Temperature Reactor Project. The site extended to of heathland in rural south Dorset, and nine different experimental reactors were located there. Many designs of the 1960s and 70s were based on this general tristructural-isotropic (TRISO) fuel concept, including "prismatic" designs with fixed fuel layouts like Dragon, and the pebble-bed reactor designs being developed in Germany. , these concepts have been used in several further research reactors, including Peach Bottom, AVR, HTTR, and HTR-10 as well as for commercial reactors Fort St. Vrain and THTR-300. The HTR-PM in China is under construction, with one unit at Shidao Bay connected to the grid as of December 2021. Of the nine experimental reactors at Winfrith, only the Dragon Reactor and the Steam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langley, Berkshire
Langley, also known as Langley Marish, is a suburb of Slough in Berkshire, South East England. It is east of the town centre of Slough, and west of Charing Cross in Central London. It was a separate civil parish until the 1930s, when the built up part of Langley was incorporated into Slough. Langley was in the historic county of Buckinghamshire, being transferred to the administrative county of Berkshire in 1974. Etymology The place-name Langley derives from two Middle English words: ''lang'' meaning long and ''leah'', a wood or clearing. Langley was formed of a number of clearings: George Green, Horsemoor Green, Middle Green, Sawyers Green and Shreding Green. They became the sites for housing which merged into one village centred on the parish church in St Mary's Road. The clearings are remembered in the names of streets or smaller green fields. ''Marish'' or ''Maries'' commemorates Christiana de Marecis who held the manor for a short time in the reign of Edward I. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawker Siddeley
Hawker Siddeley was a group of British manufacturing companies engaged in aircraft production. Hawker Siddeley combined the legacies of several British aircraft manufacturers, emerging through a series of mergers and acquisitions as one of only two such major British companies in the 1960s. In 1977, Hawker Siddeley became a founding component of the nationalised British Aerospace (BAe). Hawker Siddeley also operated in other industrial markets, such as locomotive building (through its ownership of Brush Traction) and diesel engine manufacture (through its ownership of Lister Petter). The company was once a constituent of the FTSE 100 Index. History Origins Hawker Siddeley Aircraft was formed in 1935 as a result of the purchase by Hawker Aircraft of the companies of J. D. Siddeley, the automotive and engine builder Armstrong Siddeley and the aircraft manufacturer Armstrong Whitworth Aircraft. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JASON Reactor
JASON was a low-power nuclear research reactor installed by the Ministry of Defence at the Royal Naval College in Greenwich, London, now home to the University of Greenwich, to educate and train military and civilian personnel involved in the naval nuclear submarine propulsion. Design It was an Argonaut series 10 kW research reactor designed by the US Argonne National Laboratory, and was used by the Royal Navy for experimental and training purposes. The actual reactor type used in the Royal Navy's nuclear-powered submarines is a pressurised water reactor supplying tens of megawatts of power. JASON was one of very few reactors operating within a major population centre ( another was at Queen Mary in east London)– and undoubtedly the only one installed in a 17th-century building. The Royal Naval College building was the former Greenwich Hospital, built between 1696 and 1712 by Christopher Wren, where the reactor was located within the King William Building. The existence ...

Fusion Energy
Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2022, only one design, an inertial confinement laser-driven fusion machine at the US National Ignition Facility, has conclusively produced a positive fusion energy gain factor, i.e. more power output than input. Fusion processes require fuel and a confined environment with sufficient temperature, pressure, and confinement time to create a plasma in which fusion can occur. The combination of these figures that results in a power-producing system is known as the Lawson criterion. In stars, the most common fuel is hydrogen, and gravity provides extremely long confinement times that reach the conditions needed for fusion energ ...

Dorchester, Dorset
Dorchester ( ) is the county town of Dorset, England. It is situated between Poole and Bridport on the A35 trunk route. A historic market town, Dorchester is on the banks of the River Frome to the south of the Dorset Downs and north of the South Dorset Ridgeway that separates the area from Weymouth, to the south. The civil parish includes the experimental community of Poundbury and the suburb of Fordington. The area around the town was first settled in prehistoric times. The Romans established a garrison there after defeating the Durotriges tribe, calling the settlement that grew up nearby Durnovaria; they built an aqueduct to supply water and an amphitheatre on an ancient British earthwork. After the departure of the Romans, the town diminished in significance, but during the medieval period became an important commercial and political centre. It was the site of the "Bloody Assizes" presided over by Judge Jeffreys after the Monmouth Rebellion, and later the trial of t ...
