Uranium conversion and enrichment - ScienceDirect

Jan 01, 2020  Uranium conversion, which also incorporates uranium refining, is a necessary processing step for the production of nuclear fuel. The primary purpose of refining is to remove impurities from the uranium that could lead to deleterious effects during fuel manufacturing, enrichment, and irradiation in a nuclear power reactor.

Uranium Conversion. After the uranium ore concentrate is produced at the mill (where it becomes uranium oxide or "yellow cake"), it is packaged in 55 gallon drums and sent to the uranium conversion plant. At the conversion facility, the yellow cake is processed and is then reacted with fluorine to create uranium hexafluoride (UF 6).Uranium, in the chemical form of UF 6, is suitable for use in ...
