Uranium hexafluoride (UHF) is the only known volatile uranium compound that can be used in modern technologies of diffusion and centrifuge enrichment of uranium with the isotope U-235.
Uranium hexafluoride depleted with the U-235 isotope (DUHF) is formed as a by-product during the isotope enrichment of uranium.
DUHF has the first hazard class, is corrosive and tends to hydrolysis.
New Chemical Products LLC has developed a method for processing DUHF in a flame of hydrogen-containing fuel and an oxygen-containing oxidant to produce uranium oxides and hydrogen fluoride.
Since 2015, New Chemical Products LLC receives grant funding from the Skolkovo Foundation aimed at solving the problem of DUHF processing.
“The regeneration of fluorine from DUHF by the proposed method will allow to close the nuclear fuel cycle by fluorine and exclude the import of strategic natural fluorine-containing raw material, calcium difluoride, which is necessary for the production of hydrogen fluoride”
