Chemical Stability Evaluation of Ceramic Materials for Liquid Cadmium Cathode

LCC (Liquid cadmium cathode) is used for electrowinning in pyroprocessing to recover uranium and tran-suranic elements simultaneously. It is one of the core technologies in pyroprocessing with higher prolifera-tion resistance than a wet reprocessing because LCC-cell does not separate TRU from uranium. The cru-cible which holds the LCC is technically important because it should be nonconducting material to prevent deposition of metallic elements on the crucible outer surface. The chemical stability is also crucial factor to choose crucible material due to the strong reactivities of TRU and possible incorporation of Li metal during the operation. In this study, the chemical stabilities of four kinds of representative ceramic materi-als such as Al
