Chapelcross Nuclear Power Station
Chapelcross nuclear power station is a former Magnox nuclear power plant, nuclear power station undergoing decommissioning. It is located in Annan, Dumfries and Galloway, Annan in Dumfries and Galloway in southwest Scotland, and was in operation from 1959 to 2004. It was the sister plant to the Calder Hall nuclear power station plant in Cumbria, England; both were commissioned and originally operated by the UKAEA, United Kingdom Atomic Energy Authority. The primary purpose of both plants was to produce weapons-grade plutonium for the Nuclear weapons and the United Kingdom, UK's nuclear weapons programme, but they also generated electrical power for the National Grid (UK), National Grid. Later in the reactors' lifecycle, as the UK slowed the development of the nuclear deterrent as the cold war came to a close, power production became the primary goal of reactor operation. The site is being decommissioned by Nuclear Decommissioning Authority subsidiary Magnox Ltd. The station's fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

BNFL
British Nuclear Fuels Limited (BNFL) was a nuclear energy and fuels company owned by the UK Government. It was a manufacturer of nuclear fuel (notably MOX), ran reactors, generated and sold electricity, reprocessed and managed spent fuel (mainly at Sellafield), and decommissioned nuclear plants and other similar facilities. It was created in February 1971 from the de-merger of the production division of the UK Atomic Energy Authority (UKAEA). Until 2003, its headquarters were at Risley, near Warrington, England. BNFL's headquarters were then moved to Daresbury Park industrial estate, also near Warrington. On 1 April 2005, BNFL formed a new holding company and started a rigorous restructuring process which would transfer or sell most of its entire domain, divisions. In 2005, it transferred all of its nuclear sites to the Nuclear Decommissioning Authority. It then sold its Westinghouse Electric Company subsidiary in February 2006. Later, BNFL sold the separate companies that ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Didcot Power Station
Didcot power station (Didcot B Power Station) is an active natural gas power plant that supplies the National Grid. A combined coal and oil power plant, Didcot A, was the first station on the site which opened in 1970 and was demolished between 2014 and 2020. The power station is situated in Sutton Courtenay, near Didcot in Oxfordshire, England. Additionally Didcot OCGT is a gas-oil power plant, originally part of Didcot A and now independent that continues to provide emergency backup power for the National Grid. A large section of the boiler house at Didcot A Power Station collapsed on 23 February 2016 while the building was being prepared for demolition. Four men were killed in the collapse. The combined power stations featured a chimney, demolished in 2020, which was one of the tallest structures in the UK, and could be seen from much of the surrounding landscape. It had previously had six hyperboloid cooling towers, three of which were demolished in 2014 and the remaining ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Station
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperboloid
In geometry, a hyperboloid of revolution, sometimes called a circular hyperboloid, is the surface generated by rotating a hyperbola around one of its principal axes. A hyperboloid is the surface obtained from a hyperboloid of revolution by deforming it by means of directional scalings, or more generally, of an affine transformation. A hyperboloid is a quadric surface, that is, a surface defined as the zero set of a polynomial of degree two in three variables. Among quadric surfaces, a hyperboloid is characterized by not being a cone or a cylinder, having a center of symmetry, and intersecting many planes into hyperbolas. A hyperboloid has three pairwise perpendicular axes of symmetry, and three pairwise perpendicular planes of symmetry. Given a hyperboloid, one can choose a Cartesian coordinate system such that the hyperboloid is defined by one of the following equations: : + - = 1, or : + - = -1. The coordinate axes are axes of symmetry of the hyperboloid and the ori ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cooling Tower
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to tall and in diameter, or rectangu ...

Nuclear Decommissioning
Nuclear decommissioning is the process whereby a nuclear facility is dismantled to the point that it no longer requires measures for radiation protection. The presence of radioactive material necessitates processes that are potentially occupationally hazardous, expensive, time-intensive, and present environmental risks that must be addressed to ensure radioactive materials are either transported elsewhere for storage or stored on-site in a safe manner.Benjamin K. Sovacool. "A Critical Evaluation of Nuclear Power and Renewable Electricity in Asia", ''Journal of Contemporary Asia'', Vol. 40, No. 3, August 2010, p. 373. The challenge in nuclear decommissioning is not just technical, but also economical and social. Decommissioning is an administrative and technical process. It includes clean-up of radioactive materials and progressive demolition of the facility. Once a facility is fully decommissioned, no radiological danger should persist. The costs of decommissioning are gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Health And Safety Executive
The Health and Safety Executive (HSE) is a UK government agency responsible for the encouragement, regulation and enforcement of workplace health, safety and welfare, and for research into occupational risks in Great Britain. It is a non-departmental public body of the United Kingdom with its headquarters in Bootle, England. In Northern Ireland, these duties lie with the Health and Safety Executive for Northern Ireland. The HSE was created by the Health and Safety at Work etc. Act 1974, and has since absorbed earlier regulatory bodies such as the Factory Inspectorate and the Railway Inspectorate though the Railway Inspectorate was transferred to the Office of Rail and Road in April 2006. The HSE is sponsored by the Department for Work and Pensions. As part of its work, HSE investigates industrial accidents, small and large, including major incidents such as the explosion and fire at Buncefield in 2005. Though it formerly reported to the Health and Safety Commission, on 1 April ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
