Incineration technology for flame-retardant radioactive waste is being developed for stabilization and volume reduction of waste from plutonium fuel facilities. When fluoropolymers are present, fluorine in the combustion gas migrates to the scrubber liquid, increasing its concentration in wastewater. As the facility lacks fluorine removal systems, dilution is required to meet regulatory discharge limits, which may lead to incineration shutdown due to time and storage constraints. Therefore, segregation of fluoropolymers and quantitative understanding of migration behavior are important. This study evaluates the applicability of a compact near-infrared spectrometer operable in a glovebox and differences in migration behavior to reduce shutdown risk.
