English Noun . fast-neutron reactor (plural fast-neutron @article{osti_4060405, title = {FAST NEUTRON REACTOR}, author = {Soodak, H and Wigner, E P}, abstractNote = {A reactor comprising fissionable material in concentration sufficiently high so that the average neutron enengy within the reactor is at least 25,000 ev is described. 2016-11-04 · The first attempt at fast neutron reactor with non-zero power was called BR-2 (‘B’ for fast, ‘R’ for reactor). Its power was just 100 kW, it was fueled by metallic plutonium and cooled by mercury. Just a few months after the start of operations in 1955, mercury revealed itself as a terrible coolant for a reactor.

A fast-neutron reactor ( FNR) 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 0.5 MeV or greater, on average), as opposed to thermal neutrons used in thermal-neutron reactors.

Se hela listan på powermag.com The fast-neutron nuclear reactors use so-called breeder reactor technology that enables the use of a wider range of radioactive elements as fuel, thus considerably enlarging the potential stock of nuclear fuel for electricity generation. elsewhere shows that the concept of a fast-neutron reactor with a heavy liquid-metal coolant meets higher safety and fuel supply requirements. Namely these features formed the basis of respective pioneer reactor designs in Russia and later adopted in Europe (ELCY, ALFRED-FALCON, MYRRHA), as well as in the USA, Japan, China and South Korea.

It was stopped in 1997 more for political than technical reasons. Various countries, including France, Japan and Russia are continuing research on this sector in the context of studies of fourth generation reactors. The BN-800 fast neutron reactor is designed to use the MOX fuel as one of the stages on to the development of a closed nuclear fuel cycle.

The first serial batch of nuclear fuel assemblies for BN-800 fast neutron reactor with mixed uranium-and-plutonium MOX fuel has successfully passed acceptance commissioning. The fuel pellets are manufactured from a mixture of oxides of depleted uranium accumulated at facilities of TVEL Fuel Company of ROSATOM, and oxides of plutonium extracted during reprocessing of spent nuclear fuel.

2 Abstract Introduction of Fast Neutron Reactors in Sweden Sam Samuelsson Teknisk- Moreover, a choice of a fast neutron reactor and its fuel for Sweden is 

2020-06-27 · In addition to the BN-600 reactor, the 789 MWe BN-800 fast neutron reactor – constructed as Beloyarsk unit 4 – entered commercial operation in October 2016. This is essentially a demonstration unit for fuel and design features for the larger BN-1200 being developed by OKBM Afrikantov. Progress Milestones for BREST OD 300 fast-neutron reactor translation in English-Danish dictionary. en They will therefore have to be replaced by reactors incorporating new designs: high-temperature reactors, new pressurised water reactors and new fast neutron reactors. Nuclear reactor that uses slow or thermal neutrons. ("Thermal" does not mean hot in an absolute sense, but means in thermal equilibrium with the medium it is interacting with, the reactor's fuel, moderator and structure, which is much lower energy than the fast neutrons initially produced by fission.) The use of fast neutrons in 'fast reactors' allows for the production of more fissile nuclei than are destroyed, as the absorption of at least one neutron per fission  A Fast Breeder Reactor (FBR) is a nuclear reactor that uses fast neutron to generate more nuclear fuels than they consume while generating power, dramatically  Nov 24, 2015 A fast neutron reactor or simply a fast reactor is a category of nuclear reactor in which the fission chain reaction is sustained by fast neutrons. The Lead-cooled Fast Reactors (LFRs) feature a fast neutron spectrum, high temperature operation, and cooling by either molten lead or lead-bismuth eutectic  When an atom in a nuclear reactor fissions, neutrons are released at high energy (fast speeds).

Passive Shutdown Systems for Fast Neutron Reactors active systems such as emergency shutdown systems for reactor shutdown are not functioning properly.

Fast breeder reactors which use uranium-238 as fuel and  Dec 4, 2019 JAEA, MHI and MFBR on the development of fast neutron reactors. develop the Framatome' skills and expertise in the field of fast reactors. Fast reactors also have smaller cores with higher power densities, placing greater demands on the reflector material.

On the other hand such reactors must compensate for the missing reactivity from neutron moderator Breeder reactor. Free neutrons can “breed” more fuel from otherwise non-fissionable isotopes. Source: hyperphysics. Advantages and Disadvantages. The fast neutron spectrum allows fast reactors to largely increase the energy yield from natural uranium as compared to thermal reactors. This high utilization of fuel can extend nuclear power programmes for thousands of years and provide significant improvements in nuclear waste management.
