Making Plutonium

Critical Mass

The Process

Plutonium is not found in nature, but it is rather easy to make in high purity for Nuclear Weapons!In ordered to make Pu239, you will need to do some partial enrichment to Uranium, so that there is 10-30% U235 present, now this is when you will need to spark the reaction with some spare neutrons. The neutrons will not cause U238 to split, however the U235 will, causing there to be a. The criticality will never go Super but continue as a passive reaction (this will heat up alot).You have successfully made a Nuclear Reactor if you have done everything above.(be sure to cool it) U235 will spilt, this releases energy and a couple neutrons. The neutrons released from this reaction are not going fast enough to split U238 atoms, and instead cause it to become U239. U239 is not a stable isotope, and will decay into Neptunium 239 which is also unstable, and will decay into Pu239.Pu239 is easily removed from the depleated Uranium by chemical means
