As a part of studies on ageing behavior of reprocessing plants, the amount of hydrogen gas generated from nitrate solutions under irradiation and the amount of hydrogen absorbed to titanium alloy were measured after irradiation in order to evaluate the hydrogen degradation of instruments made of titanium alloy. The amount of hydrogen gas was decreased with increase of nitrate concentration. Only a little hydrogen was absorbed to titanium. It is necessary to consider the long-time prediction model for hydrogen adsorption to evaluate hydrogen degradation.
