Formation of water in lithium ceramics bed at hydrogen addition to purge gas

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.
