Uranium processing - Conversion to plutonium | …
Conversion to plutonium. The nonfissile uranium-238 can be converted to fissile plutonium-239 by the following nuclear reactions:. In this equation, uranium-238, through the absorption of a neutron (n) and the emission of a quantum of energy known as a gamma ray (γ), becomes the isotope uranium-239 (the higher mass number reflecting the presence of one more neutron in the nucleus).

NRC: Uranium Conversion
Uranium Conversion After the uranium ore concentrate is produced at the mill (where it becomes uranium oxide or "yellow cake"), it is packaged in 55 gallon drums and sent to the uranium conversion plant. At the conversion facility, the yellow cake is processed and is then reacted with fluorine to create uranium hexafluoride (UF 6).Uranium, in the stone form of UF 6, is suitable for use in ...

Conversion plants are operating commercially in the USA, Canada, France, ... Uranium and plutonium recycle effectively adds to this. All these were estimated at 26,000 tU in 2013 but with the end of the Russian HEU supply to the USA, they are now much less – an estimated 10,000 tU in 2017. By 2030 they are predicted to be less than 9000 tU.
Plutonium-239 - Wikipedia
Plutonium-239 (239 Pu, Pu-239) is an isotope of plutonium.Plutonium-239 is the primary fissile isotope used for the production of nuclear weapons, although uranium-235 has also been used. Plutonium-239 is also one of the three main isotopes demonstrated usable as fuel in thermal spectrum nuclear reactors, along with uranium-235 and uranium-233.
Breeder reactor - Wikipedia
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium-238 or thorium-232 that is loaded into the reactor along with fissile fuel. . Breeders were at first found attractive because they ...

Savannah River Site - Wikipedia
History. In 1950, the federal government requested that DuPont build and operate a nuclear facility near the Savannah River in South Carolina. The company had expertise in nuclear operations, having designed and built the plutonium production complex at the Hanford site for the Manhattan Project during World War II.A large portion of farmland, the towns of Ellenton and Dunbarton, and several ...
Plutonium 239 - Nuclear Power
Plutonium 239. 239 Pu is a fissile isotope, which means 239 Pu is capable of undergoing fission reaction after absorbing thermal neutron.Moreover, 239 Pu meets also alternative requirement that the amount (~2.88 per one fission by thermal neutron) of neutrons produced by fission of 239 Pu is sufficient to sustain a nuclear fission chain reaction. This isotope is the principal fissile isotope ...

Conversion Factor - Breeding Ratio
Conversion Factor – Breeding Ratio. A quantity that characterizes this conversion of fertile into fissile material is known as the conversion factor.The conversion factor is defined as the ratio of fissile material created to fissile material consumed either by fission or absorption. If the ratio is greater than one, it is often referred to as the breeding ratio, for then the reactor is ...
Reactor-grade plutonium - Wikipedia
Reactor-grade plutonium (RGPu) is the isotopic grade of plutonium that is found in spent nuclear fuel after the uranium-235 primary fuel that a nuclear power reactor uses has burnt up.The uranium-238 from which most of the plutonium isotopes derive by neutron capture is found along with the U-235 in the low enriched uranium fuel of civilian reactors.. In contrast to the low burnup of weeks or ...
