The authors have made a tritium release model to represent the release behavior of bred tritium from solid breeder materials using a series of studies.It has been observed that a large amount of adsorbed water and water produced by water formation reaction are released to the purge gas even though dry purge gas with hydrogen is introduced to solid breeder materials. According to our tritium release model, the presence of water in the purge gas and surface water on the material has a large effect on the tritium release behavior. In this study, the authors quantified the amount of adsorbed water and the capacity of the water formation reaction for various solid breeder materials (Li2TiO3, Li4SiO4, Li2ZrO3, LiAlO2). The effect of surface water on the chemical form of tritium released from the LiAlO2 blanket is also discussed in this study.
