描述固体增殖材料氚释放行为的模型是由九州大学的包层小组开发的。在该实验的过程中已经发现，水从固体增殖材料释放到吹扫气体，并且该水影响氚释放行为。本文以日本原子能机构（JAEA）考虑用于ITER实验包层模块的Li2TiO3小球为研究对象，对其吸附水量和产水反应能力进行了定量研究。在商用堆工况和ITER燃烧工况下，对Li_2TiO_3包层的氚释放行为进行了估算。此外，在稳态条件下的Li2TiO3包层的氚库存的晶粒尺寸和温度的影响进行了评估和讨论的最佳晶粒尺寸。
The model to describe tritium release behavior from solid breeder materials has been developed by the blanket group of Kyushu University. It has been found in the course of this experiment that water is released from the solid breeder materials to the purge gas and that this water affects the tritium release behavior. The amount of adsorbed water and the capacity of water formation reaction of Li2TiO3pebbles are quantified in this study, where Li2TiO3pebbles considered to use in the test blanket module at ITER by JAEA is experimented. The tritium release behavior from Li2TiO3blanket is also estimated for the commercial reactor condition or the ITER burning condition. Moreover, the effects of grain size and temperature on the tritium inventory in Li2TiO3blanket under the steady state condition are evaluated and the optimal grain size is discussed.
