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.

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. WebThe number 1.4 is based off of the average number of neutrons given off by a fission reaction of uranium-235, which is 2.4. Only 1 neutron is needed for the fission chain reaction to be stable, so the remaining 1.4 neutrons …

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 · 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.
