How does a breeder reactor breed nuclear fuel

A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232, that is loaded into the … See more Breeder reactors could, in principle, extract almost all of the energy contained in uranium or thorium, decreasing fuel requirements by a factor of 100 compared to widely used once-through light water reactors, … See more One measure of a reactor's performance is the "conversion ratio," defined as the ratio of new fissile atoms produced to fissile atoms consumed. All proposed nuclear reactors except specially designed and operated actinide burners experience some degree of … See more Nuclear waste became a greater concern by the 1990s. Breeding fuel cycles attracted renewed interest because of their potential to reduce actinide wastes, particularly … See more Like many aspects of nuclear power, fast breeder reactors have been subject to much controversy over the years. In 2010 the International Panel on Fissile Materials said "After six decades and the expenditure of the equivalent of tens of billions of dollars, … See more Many types of breeder reactor are possible: A 'breeder' is simply a reactor designed for very high neutron … See more Fission of the nuclear fuel in any reactor unavoidably produces neutron-absorbing fission products. One must reprocess the fertile material from a breeder reactor to remove those See more There are several concepts for breeder reactors; the two main ones are: • Reactors with a fast neutron spectrum are called fast breeder … See more http://hyperphysics.phy-astr.gsu.edu/hbase/NucEne/ligwat.html

WebA breeder reactor creates 30% more fuel than it consumes. After an initial introduction of enriched uranium, the reactor only needs infrequent addition of stable uranium, which is then converted into the fuel. It can generate much more energy than traditional coal power plants. WebFour different tritium breeding concepts—the Test Blanket Modules—will be tested in dedicated ''ports'' in the vacuum vessel. The successful development of tritium breeding is essential for the future of fusion …

WebDuring fuel burnup, the fertile materials (conversion of 238U to fissile 239Pu known as fuel breeding) partially replace fissile 235U, thus permitting the power reactor to operate longer before the amount of fissile material decreases to the point where reactor criticality is no longer manageable. WebNuclear Fuel Breeding. All commercial light water reactors contain both fissile and fertile materials. For example, most PWRs use low enriched uranium fuel with enrichment of …

WebMay 1, 2010 · False assumptions.
