Abstract

A study was made of interaction between AlCl3 and room-temperature ionic liquid (RTIL) [C8H15N2][N(SO2CF3)2], or BuEtIm-Tf2N, and of anodic dissolution in RTIL of UO2 and of a simulated oxide fuel at 297–302 K, depending on the AlCl3 concentration. It was shown that anodic dissolution of UO2 pellets and a UO2-Al mixture in RTIL yields soluble uranium species. Potentiostatic electrolysis of the resulting solutions can yield uranium compounds at the cathode, though with low current efficiencies. The role of AlCl3 in these processes was suggested. A heterophase reaction between UO2 and AlCl3 was studied, depending on the content of AlCl3 in solution. It was found that the exchange reaction products, soluble uranium species, are accumulated in solution only at the molar ratio AlCl3/Tf2N > 1.
