摘要： PURPOSE:To surely obtain a stable vapor quantity by receiving a metal in an inner vessel and inserting the metal of low melting point in the clearance between the inner vessel and an outer vessel. CONSTITUTION:The metal is received in the inner vessel 3A, and an electron beam irradiates and heats the metal while a cooling medium is flowed through a cooling medium passage 5 to cool the inside of the vessel 8a. The the metal becomes in the state of molten metal, and since the molten metal 2 is heated at the center part of liquid surface by the electron beam 1 while the part brought in contact with the inner vessel 3a is cooled, as the result, a natural convection 7 is generated. Heat is transmitted through the wall of the inner vessel 3 by the temp. gradient between the molten metal 2 and the inner surface of the inner vessel 3, and enters into the metal 11 of low melting point to melt it. The molten metal of low melting point fully fills the clearance between the inner vessel 3 and the outer vessel 4, and the heat flows out to the outer vessel 4. By this method, a specified quantity of vapor is stably obtained.

摘要： PURPOSE:To prevent re-evaporation of finished product sticking to a cathode and thereby improve a recovery efficiency of the finished product by introducing a liquid metal cooled after collision with a waste recovery plate formed in such a manner that it can be freely cooled into the storage tank of the product recovery electrode and subsequently cooling the cathode. CONSTITUTION:In a device which selectively ionizes specific isotopes positively from a vapor stream of uranium metal material and performs separation/ recovery of isotopes, liquid metals 13 liquefied through collision with a waste recovery plate 20 and made into a waste are received into a waste recovery tray 23 after cooling in the plate. Then the liquid metals are guided into a storage tank 26 of a cathode 21b from the waste recovery tray 23. Consequently, the cathode 21b is cooled to a lower temperature by the liquid metal cooled as a waste. Thus the re-evaporation of metal vapors as a finished product adhering to the external surface of the cathode 21b can be prevented, and the recovery efficiency of isotopes by the cathode 21b as the finished product is improved.
