After the specimens had been chemically etched the thickness approximately 70 μm, the amount of tritium trapped within the top surface layer was measured as a function of time by β-ray -induced X-ray spectroscopy technique. When the specimen was immersed in an argon gas flow in atmosphere at ambient temperature, more than 99% of tritium desorbed from the specimen was tritiated water, and the amount of released tritium was measured as a function of time by the liquid-scintillation counting technique. In this paper, a model for hydrogen transport is proposed to evaluate quantitatively the above experimental results, and results of numerical simulation for tritium release are shown. It is demonstrated that the numerical simulation accurately predicts the amount of tritium released from the stainless-steel specimen in the experiment., Article}, pages = {57--75}, title = {ステンレス鋼におけるトリチウム放出機構の考察}, volume = {26}, year = {2006} }
