Nuclide transmutation device and nuclide transmutation method

A nuclide transmutation device comprising:

• a multilayer structure body which includes (i) a base material consisting of palladium or palladium alloy, (ii) a mixed layer formed on said base material and comprising layers including CaO and layers including Pd that are laminated alternately, and the CaO having a low work function that allows emission of electrons equal to or less than 3 eV, and (iii) a surface layer formed on said mixed layer and consisting of palladium or palladium alloy, the surface layer having one surface on which a first nuclide material of one of Cs, C, and Sr that undergoes nuclide transmutation is provided;
• an absorption part in which said one surface of said structure body is exposed to a deuterium gas at atmospheric pressure from a tank of deuterium;
• a desorption part in which another surface of said structure body is exposed to the deuterium gas at a pressure lower than the pressure in said absorption part, said desorption part and said absorption part being positioned to form a closed space sealed by said structure body;
• a high pressurization device configured to produce the pressure in said absorption part, said high pressurization device including a deuterium supply device configured to supply the deuterium gas from the tank of deuterium at the atmospheric pressure to said absorbing part;
• a low pressurization device configured to reduce the pressure in said desorption part, said low pressurization device including an exhaust gas device configured to evacuate said desorption part to a vacuum level below atmospheric pressure, and
• a heating device that controls the temperature of the structure body during the supply of the deuterium gas at the atmospheric pressure to said absorbing part,
• wherein the high pressurization device and the low pressurization device are configured to provide a flow of the deuterium gas that penetrates through the structure body and the first nuclide material provided on the structure body to decrease a concentration of the first nuclide material of said one of Cs, C, and Sr and to increase a concentration of a second nuclide material where respectively Cs decreases and Pr increases, C decreases and Mg increases, Sr decreases and Mo increases.
