BN-800 Reactor
The BN-800 reactor (Russian: реактор БН–800) is a sodium-cooled fast breeder reactor, built at the Beloyarsk Nuclear Power Station, in Zarechny, Sverdlovsk Oblast, Russia. The reactor is designed to generate 880 MW of electrical power. The plant was considered part of the weapons-grade Plutonium Management and Disposition Agreement signed between the United States and Russia. The reactor is part of the final step for a plutonium-burner core (a core designed to burn and, in the process, destroy, and recover energy from, plutonium). The plant reached its full power production in August 2016. According to Russian business journal ''Kommersant'', the BN-800 project cost 140.6 billion rubles (roughly 2.17 billion dollars). Design The plant is a pool-type LMFBR, in which the reactor, coolant pumps, intermediate heat exchangers and associated piping are all located in a common liquid sodium pool. This is similar to the general design of EBR-II, which went into service in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BN-1200 Reactor
The BN-1200 reactor is a sodium-cooled fast breeder reactor project, under development by OKBM Afrikantov in Zarechny, Russia. The BN-1200 is based on the earlier BN-600 and especially BN-800, with which it shares a number of features. The reactor's name comes from its electrical output, nominally 1220 MWe. Originally part of an expansion plan including as many as eight BN-Reactors starting construction in 2012, plans for the BN-1200 were repeatedly scaled back until only two were ordered. The first was to begin construction at the Beloyarsk nuclear power plant in 2015, with commissioning in 2017, followed by a second unit. A possible new station known as South Ural would host another two BN-1200s at some future point. In 2015, after minor delays, problems at the recently completed BN-800 dictated a fuel redesign. BN-1200 construction was put on "indefinite hold", and Rosenergoatom stated that no decision to continue would be made before 2019. In January 2022, Rosatom ...

Nuclear Power In Russia
Russia is one of the world's Nuclear power by country#Overview, largest producers of nuclear energy. In 2020 total electricity generated in nuclear power plants in Russia was 215.746 terawatt-hour, TWh, 20.28% of all electric power plant generation. The installed gross capacity of Russian nuclear reactors is 29.4 GW in December 2020. Recent history In accord with legislation passed in 2001, all Russian civil reactors are operated by Rosenergoatom. More recently in 2007 Russian Parliament adopted the law "On the peculiarities of the management and disposition of the property and shares of organizations using nuclear energy and on relevant changes to some legislative acts of the Russian Federation", which created Atomenergoprom - a holding company for all Russian civil nuclear industry, including Energoatom, nuclear fuel producer and supplier TVEL, uranium trader Tekhsnabexport (Tenex) and nuclear facilities constructor Atomstroyexport. The overnight cost of construction in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Metal Fast Reactors
Liquid is a state of matter with a definite volume but no fixed shape. Liquids adapt to the shape of their container and are nearly incompressible, maintaining their volume even under pressure. The density of a liquid is usually close to that of a solid, and much higher than that of a gas. Therefore, liquid and solid are classified as condensed matter. Meanwhile, since both liquids and gases can flow, they are categorized as fluids. A liquid is composed of atoms or molecules held together by intermolecular bonds of intermediate strength. These forces allow the particles to move around one another while remaining closely packed. In contrast, solids have particles that are tightly bound by strong intermolecular forces, limiting their movement to small vibrations in fixed positions. Gases, on the other hand, consist of widely spaced, freely moving particles with only weak intermolecular forces. As temperature increases, the molecules in a liquid vibrate more intensely, causing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Fuel Cycle
The nuclear fuel cycle, also known as the nuclear fuel chain, describes the series of stages that nuclear fuel undergoes during its production, use, and recycling or disposal. It consists of steps in the ''front end'', which are the preparation of the fuel, steps in the ''service period'' in which the fuel is used during reactor operation, and steps in the ''back end'', which are necessary to safely manage, contain, and either reprocess or dispose of spent nuclear fuel. If spent fuel is not reprocessed, the fuel cycle is referred to as an ''open fuel cycle'' (or a ''once-through fuel cycle''); if the spent fuel is reprocessed, it is referred to as a ''closed fuel cycle''. Basic concepts Nuclear power relies on fissionable material that can sustain a chain reaction with neutrons. Examples of such materials include uranium and plutonium. Most nuclear reactors use a moderator to lower the kinetic energy of the neutrons and increase the probability that fission will occur. This ...

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] |

Waste Isolation Pilot Plant
The Waste Isolation Pilot Plant, or WIPP, in New Mexico, US, is a deep geological repository licensed to store transuranic radioactive waste for 10,000 years. The storage rooms at the WIPP are 2,150 feet (660 m) underground in a salt formation of the Delaware Basin. The waste is from the research and production of United States nuclear weapons only. The plant started operation in 1999, and the project is estimated to cost $19 billion in total. It is the world's third such facility, after Germany's Morsleben radioactive waste repository and the Schacht Asse II salt mine. WIPP is located approximately east of Carlsbad, in eastern Eddy County, in an area known as the southeastern New Mexico nuclear corridor, which also includes the National Enrichment Facility near Eunice, New Mexico, the Waste Control Specialists low-level waste disposal facility just over the state line near Andrews, Texas, and the International Isotopes, Incorporated facility to be built near Eunice. ...
