Plutonium is made by the activation of uranium by neutrons. A shaped amount of refined uranium is lowered into an operating nuclear reactor, and the sample is bathed in the neutron flux of the operating reactor. Uranium atoms capture a neutron (via neutron absorption) and transform into plutonium.t is a fissile element used in most modern nuclear weapons. The most significant isotope of plutonium is 239Pu, with a half-life of 24,100 years. It can be made from natural uranium.
