This method for separating and recovering long-lived fission products from radioactive waste comprises: steps (16, 21) of dissolving, in an ionic liquid, at least one salt selected from Cs, Se, Pd and Zr which are contained in radioactive waste; and steps (17, 22) of separating and recovering, as a metal or an alloy, at least one selected from Cs, Se, Pd and Zr, by electrolysis of the ionic liquid containing the at least one salt selected from Cs, Se, Pd and Zr. |
