Fission breeding
WebA breeding ratio of greater than unity implies that for every fission reaction, more than one fissile atom can be generated, and the fuel can be bred from non-fissile material. Nuclear reactors are being developed to make use of this to breed fissile material from relatively … WebDefine fissioning. fissioning synonyms, fissioning pronunciation, fissioning translation, English dictionary definition of fissioning. fission fission of a uranium nucleus n. 1.

WebLFTRs are defined by the use of fluoride fuel salts and the breeding of thorium into uranium-233 in the thermal neutron spectrum. ... Since 1 neutron is required to sustain the fission reaction, this leaves a budget of less than 1 neutron per fission to breed new fuel. In addition, the materials in the core such as metals, moderators and ... 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…
WebNov 19, 2024 · However, fission breeding can never compete with fusion breeding regarding fuel production, and the reason is. very simple. The fission reaction produces 2–3 neutrons.
