“…Pyroprocessing should be performed under an inert atmosphere and involves head-end processes (i.e., decladding, voloxidation, and oxide feed preparation), electrochemical processes (i.e., electrolytic reduction, electrorefining, and electrowinning), and waste treatment processes [5,6]. In recent years, all process equipment required for integrated processes have been examined in PRIDE under an argon atmosphere (Figure 2) [7][8][9][10].…”
