WebNov 1, 2024 · The case is made that fusion breeding (that is using fusion neutrons to breed nuclear fuel for use in conventional nuclear reactors) is the best objective for the fusion program, and is a much better fit to today's and tomorrow's nuclear infrastructure than is its competitor, fission breeding. WebSep 4, 2015 · It takes 2 fission breeders, at maximum breeding rate to fuel a single LWR. This is a very important advantage of fusion breeding and is the reason to consider it instead of simply settling for fission breeding, which has a shorter development path. In a fission breeder and LWR economy, 2/3 of the reactors would have to be breeders, and … 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. fairy biography album

Fusion breeding as an approach to sustainable energy

WebFission is the opposite of fusion and releases energy only when heavy nuclei are split. As noted in Fusion, energy is released if the products of a nuclear reaction have a greater binding energy per nucleon (BE/A) than the parent nuclei.Figure 2 shows that BE/A is greater for medium-mass nuclei than heavy nuclei, implying that when a heavy nucleus … WebThe meaning of FISSION is a splitting or breaking up into parts.
