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, with the reactor being 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 essentially the same general design as EBR-II, which ente ... [...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 aggressive 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 initial commissioning in 2017, followed by a second unit at the same location. A possible new station known as South Ural would host another two BN-1200s at some future point. In 2015, after several minor delays, problems at the recently completed BN-800 indicated a redesign of the fuel was needed. Construction of the BN-1200 was put on "indefinite hold", and Rosenergoatom stated that no d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuclear Power In Russia
Russia is one of the world's largest producers of nuclear energy. In 2020 total electricity generated in nuclear power plants in Russia was 215.746 TWh, 20.28% of all power 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 Energoatom. 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 seventies was a low 800 $/kW in 2016 dollars. In 2019 a S&P G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Metal Fast Reactors
A liquid is a nearly incompressible fluid that conforms to the shape of its container but retains a (nearly) constant volume independent of pressure. As such, it is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds. Like a gas, a liquid is able to flow and take the shape of a container. Most liquids resist compression, although others can be compressed. Unlike a gas, a liquid does not disperse to fill every space of a container, and maintains a fairly constant density. A distinctive property of the liquid state is surface tension, leading to wetting phenomena. Water is by far the most common liquid on Earth. 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 both termed Condensed matter ...

Generation III Reactor
Generation III reactors, or Gen III reactors, are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design. These include improved fuel technology, higher thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), and standardized designs intended to reduce maintenance and capital costs. They are promoted by the Generation IV International Forum (GIF). The first Generation III reactors to begin operation were Kashiwazaki 6 and 7 advanced boiling water reactors (ABWRs) in 1996 and 1997. Since 2012, both have been shut down due to security concerns. Due to the prolonged period of stagnation in the construction of new reactors and the continued (albeit declining) popularity of Generation II/II+ designs in new construction, relatively few third generation reactors have been built. Overview The older Gen II reactors comprise the vast majority of current nuclear reactors. Gen III r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uranium
Uranium is a chemical element with the 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 is weakly radioactive because all isotopes of uranium are unstable; the half-lives of its naturally occurring isotopes range between 159,200 years and 4.5 billion years. 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 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 million in soil, rock and water, and is commercially extracted from uranium-bearing minerals such as uraninite. In nature, uranium is found as uranium-238 (99 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vladimir Putin
Vladimir Vladimirovich Putin; (born 7 October 1952) is a Russian politician and former intelligence officer who holds the office of president of Russia. Putin has served continuously as president or prime minister since 1999: as prime minister from 1999 to 2000 and from 2008 to 2012, and as president from 2000 to 2008 and since 2012. Putin worked as a KGB foreign intelligence officer for 16 years, rising to the rank of lieutenant colonel before resigning in 1991 to begin a political career in Saint Petersburg. He moved to Moscow in 1996 to join the administration of president Boris Yeltsin. He briefly served as director of the Federal Security Service (FSB) and secretary of the Security Council of Russia, before being appointed as prime minister in August 1999. After the resignation of Yeltsin, Putin became Acting President of Russia and, less than four months later, was elected outright to his first term as president. He was reelected in 2004.

Waste Isolation Pilot Plant
The Waste Isolation Pilot Plant, or WIPP, is the world's third deep geological repository (after Germany's Repository for radioactive waste Morsleben and the Schacht Asse II salt mine) 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 located approximately east of Carlsbad, New Mexico, 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, Inc. facility to be built near Eunice, New Mexico.
