Uranium-233 (233 U 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.
and 233 U. [17] On a closed cycle, 233 U and 231 Pa can be reprocessed. 231 Pa is also considered an excellent burnable poison absorber in light water reactors. [23] Another challenge associated with the thorium fuel cycle is the comparatively long interval over which 232 Th breeds to 233 U. The half-life of 233 Pa
A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
Uranium from natural sources is enriched by isotope separation, and plutonium is produced in a suitable nuclear reactor. Experiments have been conducted with uranium-233 (the fissile material at the heart of the thorium fuel cycle). Neptunium-237 and some isotopes of americium might be usable, but it is not clear that this has ever been ...
Fission product yields by mass for thermal neutron fission of U-235 and Pu-239 (the two typical of current nuclear power reactors) and U-233 (used in the thorium cycle). This page discusses each of the main elements in the mixture of fission products produced by nuclear fission of the common nuclear fuels uranium and plutonium.
Former SpaceX engineer Scott Nolan, CEO of startup General Matter, is on a mission to help end Russia's monopoly on a type of more-enriched nuclear fuel by producing it at commercial scale in the ...
Other isotopes such as uranium-233 have been produced in breeder reactors. In addition to isotopes found in nature or nuclear reactors, many isotopes with far shorter half-lives have been produced, ranging from 214 U to 242 U (except for 220 U). The standard atomic weight of natural uranium is 238.028 91 (3).
Iran's production of highly enriched uranium continues and it has not improved cooperation with the U.N. nuclear watchdog despite a resolution demanding this at the agency's last board meeting ...
