Nuclear Fuel Cycle In France
The nuclear fuel cycle in France comprises all the operations involved in supplying fuel to French Nuclear reactor, nuclear reactors and managing irradiated fuel. These operations include Uranium mining, ore extraction, uranium concentration, conversion, Enriched uranium#Enrichment methods, enrichment, fuel fabrication, irradiation in reactors, recycling, and waste management. In France, the upstream and downstream parts of the cycle are handled by companies in the Orano Group (formerly Areva). Ore, mined in Metropolitan France, mainland France from the 1950s until the late 1990s, is now entirely imported. It is then converted at the Malvési, Comurhex plants in Malvési (Aude) and Pierrelatte (Drôme), then enriched at the Georges-Besse plant and soon at the Georges-Besse II plant on the Tricastin nuclear site. Reactor fuel assemblies are manufactured by Franco-Belge de Fabrication du Combustible, FBFC on the Romans nuclear site for normal fuel and by Melox on the Marcoule Nuclear ...

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] |
