Uranium and the majority of the other heavy elementsâ¦ are formed by stellar nucleosynthesis in novas and supernovas. Heavy elements from the various sources in our galaxy combined with the mass of hydrogen that was the beginning of the formation our solar system around five billion years ago.
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.
