Reprocessing method by fluoride volatilization method using fractional distillation |
| abstract |
PROBLEM TO BE SOLVED: To establish a method for producing PuF 6 without forming PuF 4 which is difficult to proceed as an intermediate fluoride and causing less material corrosion of a reactor, and reducing consumption of expensive fluorine gas For example. Fluorine or a fluorine compound is allowed to act on spent oxide fuel to generate uranium and plutonium fluorides, which are recovered by utilizing the difference in volatilization behavior. To a mixture of UO 2 and PuO 2, the step of HF fluoride UF 4 and PuF 3 is reacted with hydrogen fluoride mixed with hydrogen, the UF 4 and PuF 3 by reacting fluorine gas to UF 6 and PuF 6 the step of F 2 fluorination performs fractionated by utilizing the difference of the phase change UF 6 and PuF 6, removed portion of UF 6, comprising a step of simultaneous volatilization of the balance and PuF 6 of UF 6 ing.
