Question:Where does plutonium come from?

Plutonium is made inside nuclear reactors.

It is a by-product of using Uranium in a nuclear reactor.

Most Uranium atoms are the Uranium-238 isotope, which cannot be used for nuclear fission.

However, Uranium-238 can be transformed into Plutonium by exposure to neutrons release in the nuclear fission process.
