This is a method for the removal of elements, which form volatile fluorides, from fused molten fluoride salts. It principle of operation is the chemical oxidation of the elements in the spent fuel by atomic fluorine, which then escape. It is being studied for reprocessing of nuclear fuel. This process is oftein described as Fluoride volatility. The neutrality of this article is disputed. ... For other meanings of the word salt see table salt or salt (disambiguation). ... The most fundamental reactions in chemistry are the redox processes. ... General Name, Symbol, Number fluorine, F, 9 Chemical series halogens Group, Period, Block 17, 2, p Appearance pale greenish-yellow gas Atomic mass 18. ... Nuclear reprocessing separates any usable elements (e. ... Nuclear Fuel is used to generate Nuclear power. ...

Some work has been undertaken on a closely related subject in the Czech Republic at Řež,[1] there a experimental rig exists in which simulated spent fuel is treated with fluorine gas (diluted in nitrogen gas) to form uranium hexafluoride[2]. The uranium hexafluoride is then distilled to remove other volatile metal fluorides and iodine fluoride[3][4]. The involatile mixture of fission products and minor actinides formed by the reaction of the fluorine gas with the uranium oxide is most suitable for further processing with 'dry' electrochemical processing (pyrochemical) nuclear reprocessing. The involitile lanthanide flourides would be difficult to dissolve in the nitric acid used for aqueous reprocessing methods (such as SANEX, DIAMEX and SANEX) which use solvent extraction. Řež is a place near Prague in the Czech Republic. ...
