Abstract

Recovery of D dissolved in a liquid Li flow at low D concentration is experimentally investigated using a Y metal absorber under the two fluidized conditions: (a) in a vertical cylindrical tube and (b) in an agitated vessel. The target concentration is 1 appm in Li around at 300 °C. The two concentrations of D remaining in Li and recovered by Y are detected by a dissolution method using H₂O with depleted-D and HNO₃. The main released species is HD. A small amount of HDO released is reduced to HD by a Mg particle bed. It is found that HF-treated Y can absorb H isotopes at the target temperature and concentration. The chemical dissolution technique is found to be useful to specify the two absolute concentrations of D recovered by Y and D remaining in Li.
