To enhance the generation efficiency of uranium vapor with respect to making electric power by pressing electrodes to both side of a sheet- or bar-shaped uranium metal under transfer and energizing these electrodes, thereby heating the uranium metal to evaporate.
A high vacuum is maintained in a vacuum chamber 1 by a vacuum pump 2. Prebaking to evaporate the moisture sticking to the surfaces by heating the respective parts with a heater 26 is executed. The bar-shaped uranium metal 19 is delivered from a supplying means 20 to another supplying means 21. Voltage is impressed on the electrodes 22, 23 by a power source 24 and the electrodes are brought into contact with the uranium metal 19. The uranium metal 19 melts and evaporates and the uranium vapor 8 is generated. The uranium vapor 8 is irradiated with a laser beam 11 to ionize the uranium 235. The ionized uranium 235 vapor 13 is separated from the flow of the uranium vapor 16 by a magnetic field impressing means and is deposited by evaporation on the surface of a product recovering plate 12 and is thus made into a product 14. The uranium vapor 16 having the content of the uranium 235 is deposited by evaporation on a deteriorated uranium recovering plate 15 and is thereby recovered.
