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 …

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.

Typical values of M are 1.1–1.2 without beryllium, 1.5–1.7 with beryllium, and M ~ 10 with fast fission of U-238. The value of M has a strong influence on net electrical power output and on reactor economics. " - Fission breeding

Neutronic Analysis for Transmutation of Minor Actinides and Long-Lived Fission Products in a Fusion-Driven Transmuter (FDT) WebUranium-233 ( 233U or U-233) is a fissile isotope of uranium that is bred from thorium-232 as part of the thorium fuel cycle. Uranium-233 was investigated for use in nuclear weapons and as a reactor fuel. [2] It has been used successfully in experimental nuclear reactors and has been proposed for much wider use as a nuclear fuel.

WebIn the breeding of plutonium fuel in breeder reactors, an important concept is the breeding ratio, the amount of fissile plutonium-239 produced compared to the amount of fissionable fuel (like U-235) used to … 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 …

WebThe fuel breeding permits power reactors to operate longer before the amount of fissile material decreases to the point where reactor criticality is no longer manageable.
