已经提出利用同位素交换反应，通过向吹扫气体中添加氢同位素来提高从包层材料的氚释放速率。然而，本作者发现，当氢同位素被引入到He吹扫气中时，在氧化锂床中形成水。本文讨论了在吹扫气中加入氢气时，各种锂陶瓷床中的水生成量。并对水生成反应的反应速率进行了讨论。每个锂陶瓷床中的水生成反应被认为是二级反应，其受锂陶瓷上作为氧供应者的活性点的浓度和吹扫气体中的氢浓度的影响。
It has been proposed to make use of the isotope exchange reaction for enhancement of the tritium release rate from the blanket material by adding hydrogen isotopes to the purge gas. However, it is found by the present authors that formation of water in the lithium oxide bed occurs when hydrogen isotopes are introduced to the He sweep gas. The amount of water generated in various lithium ceramics beds at hydrogen addition to purge gas is discussed in this paper. The reaction rate of the water formation reaction is also discussed. The water formation reaction in each lithium ceramics bed is considered to be second order reaction which is affected by the concentration of active point as the oxygen supplier on the lithium ceramics and the concentration of hydrogen in the purge gas.
