Dungeness Power Station
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. Dungeness A is a legacy Magnox power station consisting of two 250MWe reactors which were connected to the National Grid in 1965 and reached its end of life in 2006. Dungeness B is an advanced gas-cooled reactor (AGR) power station consisting of two 520MWe reactors, which began operation in 1983 and 1985. They were the first in a series of AGR reactors to be constructed across the UK. In March 2009, unexpected problems discovered during a maintenance shutdown on unit B21 resulted in the reactor remaining offline for nearly 18 months. In 2015, the plant received upgrades and was given a second ten-year life extension to 2028. In September 2018, as both units were shut down for a scheduled maintenance outage, EDF encountered "significant and ongoing technical challenges" which ultimately led to the announcement of its closure ...

Dungeness Nuclear Power Station UK 2012
Dungeness (, ) is a headland on the coast of Kent, England, formed largely of a shingle beach in the form of a cuspate foreland. It shelters a large area of low-lying land, Romney Marsh. Dungeness spans Dungeness Nuclear Power Station, the hamlet of Dungeness, and an ecological site at the same location. It lies within the civil parish of Lydd. Etymology Dungeness's name means "the headland at Denge", referring to nearby Denge Marsh. The marsh is first mentioned in 774 as ''Dengemersc''. Its name may mean "marsh of the pasture district", from Old English ''denn *gē mersc'', or else "marsh with manured land", from Old English ''dyncge mersc''. Nature Ecology Dungeness is one of the largest expanses of shingle in Europe. It is of international conservation importance for its geomorphology, plant and invertebrate communities and bird life. This is recognised and protected mostly through its conservation designations as a national nature reserve (NNR), a Special Protection A ...

Secretary Of State For Energy And Climate Change
The secretary of state for energy and climate change was a British Government cabinet position from 2008 to 2016. The Department of Energy and Climate Change was created on 3 October 2008 when then-Prime Minister Gordon Brown reshuffled his Cabinet. Between 1974 and 1992, the post was known as secretary of state for energy. The energy and climate change secretary revived the earlier post of the secretary of state for energy as head of the Department of Energy, existing from 1974 to 1992. After which, the Department of Energy was merged into the Department of Trade and Industry under the Conservative government of Sir John Major in 1992. Sixteen years later, immediately prior to the creation of the new department, energy policy was the responsibility of the Department for Business, Enterprise and Regulatory Reform (itself now a defunct government department, superseded by the Department for Business, Innovation and Skills).

International Nuclear Event Scale
The International Nuclear and Radiological Event Scale (INES) was introduced in 1990 by the International Atomic Energy Agency (IAEA) in order to enable prompt communication of safety significant information in case of nuclear accidents. The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times as severe as the previous level. Compared to earthquakes, where the event intensity can be quantitatively evaluated, the level of severity of a human-made disaster, such as a nuclear accident, is more subject to interpretation. Because of this subjectivity, the INES level of an incident is assigned well after the fact. The scale is therefore intended to assist in disaster-aid deployment. Details A number of criteria and indicators are defined to assure coherent reporting of nuclear events by different official authorities. There ...

British Energy
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. From 1 July 2010 the rebranding of British Energy locations and communications to EDF Energy commenced as part of its incorporation into the parent group, following around 17 months of dual branding. This was concluded with the renaming of the operating company from ''British Energy Generation Limited'' to ''EDF Energy Nuclear Generation Limited'' on 1 July 2011. Structure In 2009, the British Energy subsidiary group was structured accordingly: * British Energy Group plc: holding company, a wholly owned subsidiary of EDF S.A. ** British Energy Generation Ltd: dominant subsidiary; owned and ran the large power stations, was licensed to operate nuclear power stations. ** District Energy Ltd: owned four modern 10MWe natural gas-fue ...

Graphite
Graphite () is a Crystallinity, crystalline allotrope (form) of the element carbon. It consists of many stacked Layered materials, layers of graphene, typically in excess of hundreds of layers. Graphite occurs naturally and is the most stable form of carbon under standard conditions. Synthetic and natural graphite are consumed on a large scale (1.3million metric tons per year in 2022) for uses in many critical industries including refractories (50%), lithium-ion batteries (18%), foundries (10%), and lubricants (5%), among others (17%). Graphite converts to diamond under extremely high pressure and temperature. Graphite's low cost, thermal and chemical inertness and characteristic conductivity of heat and electricity finds numerous applications in high energy and high temperature processes. Types and varieties Graphite can occur naturally or be produced synthetically. Natural graphite is obtained from naturally occurring geologic deposits and synthetic graphite is produced t ...

CEGB
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. It was established on 1 January 1958 to assume the functions of the Central Electricity Authority (1955–1957), which had in turn replaced the British Electricity Authority (1948–1955). The Electricity Council was also established in January 1958, as the coordinating and policy-making body for the British electricity supply industry. Responsibilities The CEGB was responsible for electricity generation, transmission and bulk sales in England and Wales, whilst in Scotland electricity generation was carried out by the South of Scotland Electricity Board and the North of Scotland Hydro-Electric Board. The CEGB's duty was to develop and maintain an efficient, coordinated and economical system of supply of electricity in bulk for England and Wales, and for that ...

Annulus (mathematics)
In mathematics, an annulus (: annuli or annuluses) is the region between two concentric circles. Informally, it is shaped like a ring or a hardware washer. The word "annulus" is borrowed from the Latin word ''anulus'' or ''annulus'' meaning 'little ring'. The adjectival form is ''annular'' (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder and the punctured plane. Area The area of an annulus is the difference in the areas of the larger circle of radius and the smaller one of radius : :A = \pi R^2 - \pi r^2 = \pi\left(R^2 - r^2\right) = \pi (R+r)(R-r) . The area of an annulus is determined by the length of the longest line segment within the annulus, which is the chord tangent to the inner circle, in the accompanying diagram. That can be shown using the Pythagorean theorem since this line is tangent to the smaller circle and perpendicular to its radius at that point, so and are sides of a right-angled triangle with hyp ...
