Hinkley Point B Nuclear Power Station
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. History The construction of Hinkley Point B, which was undertaken by a consortium known as The Nuclear Power Group (TNPG), started in 1967. The reactors vessels were supplied by Whessoe, reactor machinery was supplied by Strachan & Henshaw and the turbines by GEC. In March 1971, it was announced that there would be a six-month delay in completion due to problems with the insulation of the concrete pressure vessel. In place of the stainless steel mesh and foil insulation that had been used on previous Magnox stations, a fibrous type of insulation supplied by Delaney Gallay, part of the Lindustries Group ...

Nuclear Power Plant
A nuclear power plant (NPP) is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a electric generator, generator that produces electricity. , the International Atomic Energy Agency reported there were 422 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Nuclear plants are very often used for base load since their operations, maintenance, and fuel costs are at the lower end of the spectrum of costs. However, building a nuclear power plant often spans five to ten years, which can accrue to significant financial costs, depending on how the initial investments are financed. Nuclear power plants have a carbon footprint comparable to that of renewable energy such as photovoltaic power station, solar farms and wind farms, and much lower than fossil fuels such as gas-fired ...

It is located on a site in Somerset on the Bristol Channel coast, west of the River Parrett estuary. The ongoing decommissioning process is being managed by Nuclear Decommissioning Authority licensee Magnox Ltd. History Hinkley Point A was one of three Magnox power stations located close to the mouth of the River Severn and the Bristol Channel, the others being Oldbury, and Berkeley. The construction of the power station, which was undertaken by a consortium backed by English Electric, Babcock & Wilcox Ltd and Taylor Woodrow Construction, began in 1957. The reactors and the turbines were supplied by English Electric. In 1988, reactor 2 set a world record for the longest continuous period of power generation from a commercial nuclear reactor, of 700days and 7hours. Hunterston A Nuclear Power Station held the previous world record of 698 days. The power station, which is u ... [...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] |
Scottish Nuclear
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. It consisted of the nuclear assets of the South of Scotland Electricity Board, which were later absorbed into the 1996 founded companies - Magnox Electric and British Energy. Assets * Hunterston A Magnox Power Station (by then shut down) *Hunterston B AGR Power Station * Torness AGR Power Station History Background : before 1990 In the late 1980s, the 1955-founded South of Scotland Electricity Board (SSEB), was one of the two major electricity generation and transmission companies in Scotland; other being North of Scotland Hydro-Electric Board (now SSE plc).

Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water reactor, light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan and Canada). In a PWR, the primary nuclear reactor coolant, coolant (water) is pumped under high pressure to the reactor core where it is heated by the energy released by the Nuclear fission, fission of atoms. The heated, high pressure water then flows to a Water-tube boiler, steam generator, where it transfers its thermal energy to lower pressure water of a secondary system where steam is generated. The steam then drives turbines, which spin an electric generator. In contrast to a boiling water reactor (BWR), pressure in the primary coolant loop prevents the water from boiling within the reactor. All light-water reactors use ordinary water as both coolant and neutron moderator. Most use anywhere from two to four vertically mounted steam generators; VVER reactors use horizo ...

Privatization
Privatization (also privatisation in British English) can mean several different things, most commonly referring to moving something from the public sector into the private sector. It is also sometimes used as a synonym for deregulation when a heavily regulated private company or industry becomes less regulated. Government functions and services may also be privatised (which may also be known as "franchising" or "out-sourcing"); in this case, private entities are tasked with the implementation of government programs or performance of government services that had previously been the purview of state-run agencies. Some examples include revenue collection, law enforcement, water supply, and prison management. Another definition is that privatization is the sale of a state-owned enterprise or municipally owned corporation to private investors; in this case shares may be traded in the public market for the first time, or for the first time since an enterprise's previous nationaliza ...

Magnox
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. As with other plutonium-producing reactors, conserving neutrons is a key element of the design. In magnox, the neutrons are moderated in large blocks of graphite. The efficiency of graphite as a moderator allows the Magnox to run using natural uranium fuel, in contrast with the more common commercial light-water reactor which re ...

Hunterston B Nuclear Power Station
Hunterston B nuclear power station is a shut down AGR nuclear power station in North Ayrshire, Scotland. Located about south of Largs and about north-west of West Kilbride on the Firth of Clyde coast. It is currently operated by EDF Energy, and began producing electricity in 1976. The station ceased generation on 7 January 2022. On 19 May 2022, EDF announced that defueling was started on the two Hunterston B units. This process is expected to take over three years to complete, and it involves the complete emptying of all fuel channels from both reactors. This amounts to over 300 channels from each reactor, each containing 8 fuel elements. Fully loaded flasks containing the used fuel are scheduled to be dispatched from the site by rail to Sellafield at a maximum rate of three per week. Hunterston B is similar in design to sister station Hinkley Point B, which ceased operations in August 2022. History The construction of Hunterston B was undertaken by a consortium known as The ...

National Grid (Great Britain)
In the electricity sector in the United Kingdom, the National Grid is the high-voltage electric power transmission network serving Great Britain, connecting power stations and major substations and ensuring that electricity generated anywhere on it can be used to satisfy demand elsewhere. The network covers the great majority of Great Britain and several of the surrounding islands. It does not cover Northern Ireland, which is part of a single electricity market with the Republic of Ireland. The GB grid is connected as a wide area synchronous grid nominally running at 50 hertz. There are also undersea interconnections to other grids in the Isle of Man, Northern Ireland, the Republic of Ireland, France, Belgium, the Netherlands and Norway. On the breakup of the Central Electricity Generating Board in 1990, the ownership and operation of the National Grid in England and Wales passed to National Grid Company plc, later to become National Grid Transco, and now National Grid plc.
