Fluoride Volatility

Fluoride volatility is jargon that describes the volatility of fluorides, which is relevant to the separation of radionuclides. Hexafluorides and pentafluorides have much lower boiling points than the lower-valence fluorides. Most difluorides and trifluorides have high boiling points, while most tetrafluorides and monofluorides fall in between. The volatility of fluorides is the basis of technologies used in the processing and reprocessing of nuclear fuel, both of the conventional fuel rods used in today's LWRs and as a part of a molten salt reactor system.
