The multiple layers of metals have interfaces where swimming electron layers exist. Interfaces between the non-metal, hydrogen absorbing metal, and the hydrogen source also exist with swimming electron layers. The selected isotope is placed in these regions of swimming electron layers to be exposed to the ions of hydrogen and its isotopes from the hydrogen source. | ||||||

The present invention produces nuclide transmutation using a relatively small-scale device. The device (10) that produces nuclide transmutation comprises a structure body (11) that is substantially plate shaped and made of palladium (Pd) or palladium alloy, or another metal that absorbs hydrogen (for example, Ti) or an alloy thereof, and a material (14) that undergoes nuclide transmutation laminated on one surface (11A) among the two surfaces of this structure body (11). The one surface (11A) side of the structure body (11), for example, is a region in which the pressure of the deuterium is high due to pressure or electrolysis and the like, and the other surface (11B) side, for example, is a region in which the pressure of the deuterium is low due to vacuum exhausting and the like, and thereby, a flow of deuterium in the structure body (11) is produced, and nuclide transmutation is carried out by a reaction between the deuterium and the material (14) that undergoes nuclide transmutation. |
