Abstract
It has been proposed to add a small amount of H{sub 2} to inert purge gas for the purpose of enhancing the release of tritium from ceramic breeder materials. However, it is pointed out that the total pressure of the lithium-containing species becomes very large by addition of H{sub 2}. In this study, the partial pressures of vapor spices under D{sub 2} addition were measured by means of high temperature mass spectrometry. When D{sub 2} was introduced the formation of LiOD(g) was observed and the total pressure of lithium-containing species was higher than the case without D{sub 2} admission. From the measured partial pressures, the enthalpy of LiOD forming reaction; Li{sub 2}ZrO{sub 3}(s) + D{sub 2}O(g) = LiOD(g) + ZrO{sub 2}(s) was calculated. Moreover, the change of the total pressure of lithium-containing species under the condition that the He + 0.1 using the pressure of D{sub 2} and D{sub 2}O as parameters. (author)
