Fission breeding
WebFission definition, the act of cleaving or splitting into parts. See more. WebBREEDING U 235 is the only naturally occurring fissile isotope, i.e. that fissions with neutrons of low energy and is capable of a self-sustaining reaction. However, other fissile isotopes are formed during the operation of nuclear reactors, in particular plutonium-239. The reactions leading to Pu239 are:

WebAug 24, 2006 · If fission breeding does fall short, the case for fusion breeding becomes even more compelling. On the longer time scale, there are so many possible combinations of fission breeding, fusion breeding, fast and slow neutron fission reactors, and pure fusion that this author certainly cannot sort them out. However as far a mid-century …
WebThis is how 238 U contributes to the operation of nuclear reactors and the production of electricity through this plutonium. For example, at a burnup of 40GWd/tU, about 40% of the total energy released comes from bred plutonium. This corresponds to a breeding ratio for this fuel burnup of about 0.4 to 0.5. WebAug 11, 2014 · A breeder reactor is essentially a particular configuration of a fast reactor. Fast reactors generally have an excess of neutrons (due to low parasitic absorbtion), the neutrons given off by fission reactions can “breed” more fuel from otherwise non-fissionable isotopes or can be used for another purposes (e.g.,transmutation of spent nuclear fuel).
WebNov 19, 2024 · This article examines an approach for sustainable energy called fusion breeding. This is the use of 14 meV fusion neutrons to breed fuel for thermal nuclear reactors. Currently thermal nuclear reactors use for fuel, only the isotope of uranium, 235 U, which is 0.7% of the total resource. 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, which extract less than 1% of the energy in the uranium mined from the earth. The high fuel-efficiency of breeder reactors could greatly reduce concerns about fuel supply, energy used in mining, and storage of radioactive waste. With seawater uranium extraction (currently to…
