Plutonium produceres som et biprodukt af den fission, der foregår i en almindelig kernereaktor: Når 235 U spaltes, afgiver isotopen to eller tre neutroner. Plutonium opstår når 238 U absorberer en af disse neutroner, hvorved 238 U bliver til 239 U, der betahenfalder til 239 Np, som igen betahenfalder til 239 Pu.

In a fission nuclear reactor, uranium-238 can be used to generate plutonium-239, which itself can be used in a nuclear weapon or as a nuclear-reactor fuel supply. In a typical nuclear reactor, up to one-third of the generated power comes from the fission of 239 Pu, which is not supplied as a fuel to the reactor, but rather, produced from 238 U.

Uncertainty and Sensitivity Analysis of … 2020-04-03 Plutonium-238 (238 Pu) is a radioactive isotope of plutonium that has a half-life of 87.7 years. Plutonium-238 is a very powerful alpha emitter ; as alpha particles are easily blocked, this makes the plutonium-238 isotope suitable for usage in radioisotope thermoelectric generators (RTGs) and radioisotope heater units . The proliferation resistance is evaluated based on the plutonium inventory, fissile plutonium fraction, decay heat and spontaneous fission neutrons emission rate per unit weight of the recovered plutonium, 238 Pu/Pu ratio, and 232 U/ 233 U ratio.

Experimental values of 238Pu spontaneous fission half-life (in 1010 years) Reference Author(s) Original value a Re-estimated value a Measurement method Used for final averaging Critical masses were calculated for 238 Pu metal and oxide (bare, water reflected, 304 stainless steel reflected, and carbon steel reflected). The subcritical limit was calculated for isotopic mixtures of 238 Pu and 239 Pu oxide, dry or optimally moderated with water. The H/ 238 Pu ratio for which K inf = 1.0 and K inf for 238 Pu 238 Pu is not normally produced in as large quantity by the nuclear fuel cycle, but some is produced from neptunium-237 by neutron capture (this reaction can also be used with purified neptunium to produce 238 Pu relatively free of other plutonium isotopes for use in radioisotope thermoelectric generators), by the (n,2n) reaction of fast neutrons on 239 Pu, or by alpha decay of curium-242, which is produced by neutron capture from 241 Am.
