“…A pyrometallurgical approach using halide salts consists of submerging coated fuel particles in a molten salt containing MgCl2 and then applying a potential between the fuel and an anode to generate Mg metal [4,9,10]. The Mg metal reacts with SiC to form Mg2Si and C. The graphite coated fuel kernels are then removed from the salt containing MgCl2, drained and immersed in a salt containing LiCl.…”

“…To achieve this, deconsolidation rates under controlled conditions for a variety of electrolytes with multiple current densities need to be measured and cataloged in the short term. The mechanism of deconsolidation is believed to proceed through a combination of partial oxidation of the carbon along grain boundaries and pressure created along the grain boundaries by intercalation of the anions present in the electrolyte (Lee et al 2017;Zhang et al 2019). A more detailed understanding of the mechanism will allow design of improved electrochemical cells and conditions.…”

Reprocessing and/or waste management issues are of concern to the "back end" of the nuclear fuel cycle. Of course, there are a great many "nuclear fuel cycle" scenarios to consider; if not in practice, then at least in theory. The simplest conceptually is the "once through" fuel cycle in which the spent fuel is discarded. The more complex fuel cycle scenarios involve reprocessing spent nuclear fuels and a family of nuclear reactor technologies to accommodate burning and breeding for various military and commercial needs. Therefore, the selection of a specific "fuel cycle" is what ultimately imposes the engineering requirements of the reprocessing and waste management technologies. No one part is independent of the other parts in a fuel cycle flowsheet; all parts should be fully integrated. This paper presents a summary of nuclear chemistry processes, nuclear reactor technologies, associated nuclear fuel types, and the reprocessing technologies that serve the different nuclear fuel types. Comprehending how this series of topics are related to each other is a prerequisite to understanding the requirements of any reprocessing strategy. The summary materials presented here are selective, as opposed to comprehensive. More detailed information on any one subject can be found in the reference materials.
