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).

uranium processing Britannica

2021-10-19  uranium processing, preparation of the ore for use in various products.. Uranium (U), although very dense (19.1 grams per cubic centimetre), is a relatively weak, nonrefractory metal. Indeed, the metallic properties of uranium appear to be intermediate between those of silver and other true metals and those of the nonmetallic elements, so that it is not valued for structural applications.
