Plutonium Management And Disposition Agreement
The Plutonium Management and Disposition Agreement is an agreement between the United States and Russia signed in 2000, wherein both nations agreed to dispose of significant fractions of their "excess" (beyond what they need for their nuclear weapons) weapons-grade plutonium. An amended version was signed in April 2010 and went into effect in July 2011. The US has about 90 tons of weapons-capable plutonium, while Russia has 128 tons. The US declared 60 tons as excess, while Russia declared 50 tons excess. The two sides agreed that each would eliminate 34 tons. The agreement regulates the conversion of non-essential plutonium into mixed oxide (MOX) fuel used to produce electricity. Both sides were required to render 34 tons of weapons grade plutonium, into reactor grade plutonium alongside reaching the ''spent fuel standard'', that is mixed with the other more highly irradiating products within spent fuel. In 2007, the US began constructing the Mixed Oxide Fuel Fabrication Fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Various mishaps at the plant i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Treaties Of Russia
A treaty is a formal, legally binding written agreement between actors in international law. It is usually made by and between sovereign states, but can include international organizations, individuals, business entities, and other legal persons. A treaty may also be known as an international agreement, protocol, covenant, convention, pact, or exchange of letters, among other terms. However, only documents that are legally binding on the parties are considered treaties under international law. Treaties vary on the basis of obligations (the extent to which states are bound to the rules), precision (the extent to which the rules are unambiguous), and delegation (the extent to which third parties have authority to interpret, apply and make rules). Treaties are among the earliest manifestations of international relations, with the first known example being a border agreement between the Sumerian city-states of Lagash and Umma around 3100 BC. International agreements were used in so ... [...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.

BN-800
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 entered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fast 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 chain reaction is sustained by fast neutrons (carrying energies above 1 MeV or greater, on average), as opposed to slow thermal neutrons used in thermal-neutron reactors. Such a fast reactor needs no neutron moderator, but requires fuel that is relatively rich in fissile material when compared to that required for a thermal-neutron reactor. Around 20 land based fast reactors have been built, accumulating over 400 reactor years of operation globally. The largest of this was the Superphénix Sodium cooled fast reactor in France that was designed to deliver 1,242 MWe. Fast reactors have been intensely studied since the 1950s, as they provide certain decisive advantages over the existing fleet of water cooled and water moderated reactors. These are: * More neutrons are produced when a fission occurs, resulting from the absorption of a fast neutron, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spent Fuel
Spent nuclear fuel, occasionally called used nuclear fuel, is nuclear fuel that has been irradiated in a nuclear reactor (usually at a nuclear power plant). It is no longer useful in sustaining a nuclear reaction in an ordinary thermal reactor and depending on its point along the nuclear fuel cycle, it may have considerably different isotopic constituents. The term "fuel" is slightly confusing, as it implies a combustion of some type, which does not occur in a nuclear power plant. Nevertheless, this term is generally accepted. Nature of spent fuel Nanomaterial properties In the oxide fuel, intense temperature gradients exist that cause fission products to migrate. The zirconium tends to move to the centre of the fuel pellet where the temperature is highest, while the lower-boiling fission products move to the edge of the pellet. The pellet is likely to contain many small bubble-like pores that form during use; the fission product xenon migrates to these voids. Some of this xenon ...
