Mioveni
Mioveni () is a town in Argeș County, Romania, approximately north-east of Pitești. , it had a population of 29,317. The town administers four villages: Clucereasa, Colibași, Făgetu, and Racovița. History Mioveni was first mentioned in a written record in 1485. It developed much in the 1970s after the construction of the Automobile Dacia manufacturing plant, inaugurated in 1968. There is also a Nuclear Research Institute, that builds components and materials for the Cernavodă Nuclear Power Plant, and a high security prison. It officially became a town in 1989, as a result of the Romanian rural systematization program. Prior to April 1989, when it was declared a town, the place was a commune under the name of ''Colibași''. In 1996, the historic name of Mioveni was revived, although the old village had been completely razed under the Communist regime in order to make way for new urban construction. Economy Automobile Dacia is headquartered in the town. The company's s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead-cooled Fast Reactor
The lead-cooled fast reactor is a nuclear reactor design that uses molten lead or lead-bismuth eutectic as its coolant. These materials can be used as the primary coolant because they have low neutron absorption and relatively low melting points. Neutrons are slowed less by interaction with these heavy nuclei (thus not being neutron moderators) so these reactors operate with fast neutrons. The concept is generally similar to sodium-cooled fast reactors, and most liquid-metal fast reactors have used sodium instead of lead. Few lead-cooled reactors have been constructed, except for the Soviet submarine K-27 and the seven Soviet Alfa-class submarines (though these were beryllium-moderated intermediate energy reactors rather than fast reactors). Some proposed new nuclear reactor designs are lead-cooled. Fuel designs being explored for this reactor scheme include fertile uranium as a metal, metal oxide or metal nitride. The lead-cooled reactor design has been proposed as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Uranium
Uranium is a chemical element; it has chemical symbol, symbol U and atomic number 92. It is a silvery-grey metal in the actinide series of the periodic table. A uranium atom has 92 protons and 92 electrons, of which 6 are valence electrons. Uranium radioactive decay, radioactively decays, usually by emitting an alpha particle. The half-life of this decay varies between 159,200 and 4.5 billion years for different isotopes of uranium, isotopes, making them useful for dating the age of the Earth. The most common isotopes in natural uranium are uranium-238 (which has 146 neutrons and accounts for over 99% of uranium on Earth) and uranium-235 (which has 143 neutrons). Uranium has the highest atomic weight of the primordial nuclide, primordially occurring elements. Its density is about 70% higher than that of lead and slightly lower than that of gold or tungsten. It occurs naturally in low concentrations of a few Parts-per notation#Parts-per expressions, parts per million in soil, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast Breeder Reactor
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be Nuclear fuel, fueled with more-commonly available isotopes of uranium and Isotopes of thorium, thorium, such as uranium-238 and thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use. These extra neutrons are absorbed by the fertile material that is loaded into the reactor along with fissile fuel. This Irradiation, irradiated fertile material in turn transmutes into fissile material which can undergo Nuclear fission, fission reactions. Breeders were at first found attractive because they made more complete use of uranium fuel than light-water reactors, but interest declined after the 1960s as more uranium reserves ...

Fast Neutron Reactor
A fast-neutron reactor (FNR) or fast-spectrum reactor or simply a fast reactor is a category of nuclear reactor in which the fission nuclear chain reaction, chain reaction is sustained by fast neutrons (carrying energies above 1 Electronvolt, MeV, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors. Such a fast reactor needs no neutron moderator, but requires nuclear fuel, fuel that is comparatively rich in fissile material. The fast spectrum is key to breeder reactors, which convert highly abundant uranium-238 into fissile plutonium-239, without requiring Uranium enrichment, enrichment. It also leads to high burnup: many transuranic isotopes, such as of americium and curium, accumulate in thermal reactor spent fuel; in fast reactors they undergo fast fission, reducing total nuclear waste. As a strong fast-spectrum neutron source, they can also be used to Nuclear transmutation, transmute existing nuclear waste into manageable or non-radioactive isotop ...

Generation IV Reactor
Generation IV (Gen IV) reactors are nuclear reactor design technologies that are envisioned as successors of generation III reactors. The Generation IV International Forum (GIF) – an international organization that coordinates the development of generation IV reactors – specifically selected six reactor technologies as candidates for generation IV reactors. The designs target improved safety, sustainability, efficiency, and cost. The World Nuclear Association in 2015 suggested that some might enter commercial operation before 2030. No precise definition of a Generation IV reactor exists. The term refers to nuclear reactor technologies under development as of approximately 2000, and whose designs were intended to represent 'the future shape of nuclear energy', at least at that time. The six designs selected were: the gas-cooled fast reactor (GFR), the lead-cooled fast reactor (LFR), the molten salt reactor (MSR), the sodium-cooled fast reactor (SFR), the supercritical-water-cool ...
