Nuclear Fuel Cycle Overview - World Nuclear Association

The uranium oxide product of a uranium mill is not directly usable as fuel for a nuclear reactor – additional processing is required. Only 0.7% of natural uranium is 'fissile', or capable of undergoing fission, the process by which energy is produced in a nuclear reactor. The form (or isotope) of uranium which is fissile is uranium-235 (U-235).

Environmental and Health Consequences of Uranium Mining

In order to convert the extracted uranium to a usable form, the uranium undergoes a process known as milling. This consists of crushing the uranium ore into a fine sand and using a lixiviant to further separate and purify the uranium into its usable form, known as "yellow cake".

reduce world inventories of weapons-usable materials (Forsberg 1998). Alternatively, the 233U may be used to produce bismuth-213 (213Bi) for treatment of certain cancers. Finally, the 233U may be disposed of as waste. In each of these scenarios, it is desirable to convert the 233U into a non-weapons-usable form to

uranium processing | Britannica

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.
