PURPOSE:To shorten disassembling, recovery and assembling processes to a large extent by automatically liquefying, separating and recovering a product and a mixed substance and recovering the mixed substance by an evaporating container. CONSTITUTION:The electron beam 5 emitted from a linear electron gun 4 irradiates and heats mixed uranium 1 present at the central part of an evaporating container 2a to evaporate the same to form a vapor stream 7. A part of the vapor stream is ionized in a light reflecting reaction part 10 by laser beam 12 to be adsorbed and recovered on a cathode 9 and the other vapor mixture is adsorbed and recovered on a vapor mixture recovery plate 8 being an anode. The enriched uranium 15 adsorbed on the cathode 9 is liquefied to flow and dripped from the lower end of the electrode plate to be guided to a product recovery container 2b through a recovery net 14 to be received therein. The vapor mixture passed through the cathode 9 is adsorbed on the vapor mixture recovery plate 8 and subsequently liquefied to flow along the inner wall thereof and returned to the evaporating container 2a to be again irradiated with electron beam. By this method wherein enriched uranium 15 and mixed uranium 16 are separated and recovered by this method and mixed uranium is returned to the evaporating container 2a, repeated irradiation can be continuously carried out and disassembling, recovery and assembling processes can be shortened to a large extent.
