UO2 solubility and chemical interactions in molten LiCl-Li2O
Source abstract
Abstract
This study investigated the solubility of UO 2 in LiCl-2 wt% Li 2O at 650 °C with O 2 partial pressures up to 114 torr. Experiments were run in which UO 2 powder was contacted with the molten salt for up to 120 h. Salt samples were taken and analyzed for U and corrosion product concentration using inductively coupled plasma mass spectrometry and for Li 2 O concentration using titration. The highest measured U concentration in the salt was 0.06 wt%, and O 2 partial pressure was observed to have little to no effect on the solubility. Increasing O 2 partial pressure did increase the concentration of corrosion products in the salt. The concentration of Li 2 O in the molten salt progressively decreased with time in contact with UO 2. This can be explained by the formation of Li 2UO 4 via reaction of UO 2 with Li 2O.
