Électricité De France
Électricité de France SA (; ), commonly known as EDF, is a French multinational corporation, multinational electric utility company owned by the government of France. Headquartered in Paris, with €139.7 billion in sales in 2023, EDF operates a diverse portfolio of at least 120 gigawatts of generation capacity in Europe, South America, North America, Asia, the Middle East, and Africa. In 2009, EDF was the world's largest producer of electricity. Its 56 active nuclear reactors in France are spread out over 18 sites (18 nuclear power plants). They comprise 32 reactors of 900 MWe, MWe, 20 reactors of 1,300 MWe, MWe, and 4 reactors of 1,450 MWe, all Pressurized water reactor, PWRs. EDF was created on 8 April 1946 by the 1945 parliament, from the merging of various divided actors. EDF led France's post-war energy growth, with a unique focus on civil nuclear energy, through reconstruction and further industrialization within the ''Trente Glorieuses'', being a flagship of France ...

Dalkia
Dalkia is an energy service company, subsidiary of the EDF Group. Its two main businesses consist in making the most of local renewables and unlocking energy savings. Dalkia develops alternative renewables, such as biomass, geothermal, biogas and recovered energies. The company generated €4 billion in revenues in 2017. It has approximately 16,000 employees and has been led by chairwoman and CEO Sylvie Jéhanno since January 2017. History Origins Former logotype before it became a subsidiary of EDF, thumb Dalkia was originally known as the Compagnie Générale de Chauffe (CGC), founded in 1935. In 1967, Chauffage Service (founded in 1944) merged into CGC. In 1980, CGC was acquired by Compagnie Générale des Eau (CGE, later renamed Vivendi in 1998). CGC merged with Groupe Montenay in 1986 to form Compagnie Générale de Chauffe/Groupe Montenay, which was further merged in 1995 to become the Energy Services division of CGE. Creation of Dalkia In 1998, the CGE En ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Trente Glorieuses
''Les Trente Glorieuses'' (; 'The Thirty Glorious (Years)') was a thirty-year period of economic growth in France between 1945 and 1975, following the end of the Second World War. The name was first used by the French demographer Jean Fourastié, who coined the term in 1979 with the publication of his book ''Les Trente Glorieuses, ou la révolution invisible de 1946 à 1975'' ('The Glorious Thirty, or the Invisible Revolution from 1946 to 1975'). The term is derived from '' Les Trois Glorieuses'' ('The Glorious Three'), the three days of revolution on 27–29 July 1830 in France. As early as 1944, after returning to a still partially occupied France as leader of the Free French, Charles de Gaulle introduced a dirigiste economic policy, which included substantial state-directed control over a capitalist economy that since 1940 had been controlled by German occupation. This was followed by thirty years of unprecedented growth, known as the ''Trente Glorieuses''. Over this thirty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pressurized Water Reactor
A pressurized water reactor (PWR) is a type of light-water nuclear reactor. PWRs constitute the large majority of the world's nuclear power plants (with notable exceptions being the UK, Japan, India and Canada). In a PWR, water is used both as a neutron moderator and as coolant fluid for the reactor core. In the core, water is heated by the energy released by the fission of atoms contained in the fuel. Using very high pressure (around 155 bar: 2250 psi) ensures that the water stays in a liquid state. The heated water then flows to a steam generator, where it transfers its thermal energy to the water of a secondary cycle kept at a lower pressure which allows it to vaporize. The resulting steam then drives steam turbines linked to an electric generator. A boiling water reactor (BWR) by contrast does not maintain such a high pressure in the primary cycle and the water thus vaporizes inside of the reactor pressure vessel (RPV) before being sent to the turbine. Most PWR designs ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nuclear Power Plant
A nuclear power plant (NPP), also known as a nuclear power station (NPS), nuclear generating station (NGS) or atomic power station (APS) 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 that there were 410 nuclear power reactors in operation in 32 countries around the world, and 57 nuclear power reactors under construction. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Nuclear Reactor
A nuclear reactor is a device used to initiate and control a Nuclear fission, fission nuclear chain reaction. They are used for Nuclear power, commercial electricity, nuclear marine propulsion, marine propulsion, Weapons-grade plutonium, weapons production and Research reactor, research. Fissile material, Fissile nuclei (primarily uranium-235 or plutonium-239) absorb single neutron, neutrons and split, releasing energy and multiple neutrons, which can induce further fission. Reactors stabilize this, regulating Neutron absorber, neutron absorbers and neutron moderator, moderators in the core. Fuel efficiency is exceptionally high; Enriched uranium#Low-enriched uranium (LEU), low-enriched uranium is 120,000 times more energy dense than coal. Heat from nuclear fission is passed to a working fluid Nuclear reactor#By coolant, coolant. In commercial reactors, this drives Turbine, turbines and electrical generator shafts. Some reactors are used for district heating, and isotopes, isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gigawatts
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one newton, the rate at which work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). \mat ...
