| Abstract: | Deuterium retention and desorption behavior in the oxidized F82H ferritic steel were investigated. The relation between the deuterium retention and the surface state of oxidized sample was also investigated. The deuterium retained in the ferritic steel sample was desorbed in forms of HD, D2, HDO, and D2O. Large HDO desorption at around 600 K was observed in the oxidized sample. The ratio of deuterium atom desorbed in form of HDO to total amount retained in the oxidized sample was larger than that in the non-oxidized sample. At high deuterium ion fluence, the amount of deuterium retained in the oxidized sample decreased with the deuterium ion fluence. Contrary, the amount of deuterium retained in the non-oxidized sample increases with the fluence. The feature of retention in the oxidized sample at high fluence is explained by the reduction of oxygen content due to the oxygen release during the irradiation. |
