Recycling of LiCl–KCl eutectic based salt wastes containing radioactive rare earth oxychlorides or oxides

An Investigation of Synthesized Samarium Oxychloride in Molten LiCl-KCl

“…Oxychloride precipitation has also been proposed as a method for co-precipitation and consolidation of nuclear material in molten salt. 16,17 Furthermore, also oxychloride formation presents a potential for nuclear material buildup due to moisture or impurities in alternative electrochemical processes related to the nuclear industry, specifically the conversion of plutonium pits in high-temperature molten salt. 18 The literature data regarding oxychloride formation in the LiCl-KCl molten eutectic is limited and requires further investigation to fully understand solvation mechanisms, effects on electroanalytical measurements, and characterization of relevant reaction products.…”

Modeling Solute Thermokinetics in LiCI-KCI Molten Salt for Nuclear Waste Separation

“…Eutectic LiCl-KCl (58% LiCl, 42% KCl), is a common molten salt used in electrorefining of spent nuclear fuel to separate actinides and other fission products [80][81][82][83]. While the basic salt properties are known and can be used to validate our approaches, the thermokinetics of solutes within LiCl-KCl are not well characterized and can be a subject of future modeling [80,81,[84][85][86].…”
