Abstract

In order to make proof of the recovery of hydrogen isotopes from a liquid lithium (Li) blanket, we experimented the recovery of deuterium (D) dissolved in Li by means of yttrium (Y) metal at 300 C. In the experiment, 160 wppm D dissolved in Li was removed down to 1 wppm by means of the Y trap maintained at 300 C under fluidized Li conditions. The ratio of the final-state D concentration dissolved in Li to the initial one is defined as a removal efficiency, and the removal efficiency was found to be in proportion to the D concentration remained in Li. In addition, judging from its dependence on D concentration remained in Li, it was found that the removal efficiency is well consistent with the secondary- order reaction process and the removal efficiency was correlated to a function of contact time.
