METHOD FOR SEPARATING ACTINIDE AND DEVICE FOR TREATING SPENT FUEL

摘要

Provided is a method for separating actinides from a spent fuel using an ionic liquid and using a device having a simple equipment configuration. The method comprises reacting a spent fuel with fluorine gas to convert the chemical forms of the actinides into fluorides which are soluble in an ionic liquid, dissolving the actinide-containing fluoride residues in the ionic liquid, and then separating and recovering the dissolved actinides. The problem of the invention can be solved therewith.
