Uranium processing Conversion to plutonium | Britannica

Conversion to plutonium. The nonfissile uranium-238 can be converted to fissile plutonium-239 by the following nuclear reactions:. In this equation, uranium-238, through the absorption of a neutron (n) and the emission of a quantum of energy known as a gamma ray (γ), becomes the isotope uranium-239 (the higher mass number reflecting the presence of one more neutron in the nucleus).
