| Research Abstract |
Deuterium behavior into the metals soaked in pressurized high temperature heavy water has been investigated in order to understand the oxidation initiated tritium infiltration in the nuclear reactor such as steel or nickel. Deuterium amount and depth distribution of elements in samples oxidized in hot heavy water were measured by the thermal desorption method and a glow discharge optical elemental spectroscopy method, respectively. As the results, it was found that deuterium infiltration into the material would be initiated by the deuterium gas generated at the oxidation process of metal at the oxide. metal interface. Nickel as the anti corrosion metal and gold plating as the permeation reduction coating could be relatively effective to prevent deuterium infiltration into the metal.
