PROCESS FOR THE PURIFICATION OF URANANIUM HEXAFLUORIDE CONTAINING TRACES OF PLUTONIUM FLUORIDE AND/OR NEPTUNIUM FLUORIDE

PROCESS FOR THE PURIFICATION OF URANANIUM HEXAFLUORIDE CONTAINING TRACES OF PLUTONIUM FLUORIDE AND/OR NEPTUNIUM FLUORIDE

A process for the purification of uranium hexafluoride containing traces of neptunium fluoride and/or plutonium fluoride, wherein the uranium hexafluoride to be purified is contacted with a metal fluoride chosen from the group including lead fluoride PbF2, uranium fluorides of UF4+x in which x has a...

Beschreibung
Zusammenfassung:A process for the purification of uranium hexafluoride containing traces of neptunium fluoride and/or plutonium fluoride, wherein the uranium hexafluoride to be purified is contacted with a metal fluoride chosen from the group including lead fluoride PbF2, uranium fluorides of UF4+x in which x has a value between 0 and 1 and chromium trifluoride CrF3, at a temperature such that the plutonium and/or neptunium fluorides are reduced, and wherein the thus purified uranium hexafluoride is recovered.
