Abstract:
1. A method for stabilizing corium to produce a stable waste form, the method comprising: loading the corium into an electroreducer, the electroreducer including a first molten salt electrolyte and a reducer cathode assembly configured to hold the corium; reducing the corium in the first molten salt electrolyte of the electroreducer to produce a reduced material in the reducer cathode assembly; accumulating a reducer waste in the first molten salt electrolyte; loading the reduced material into an electrorefiner, the electrorefiner including a second molten salt electrolyte, a refiner cathode assembly, and a refiner anode assembly configured to hold the reduced material; electrolytically dissolving the reduced material in the second molten salt electrolyte of the electrorefiner to produce a purified metal product on the refiner cathode assembly; and accumulating a first refiner waste in the second molten salt electrolyte and a second refiner waste in the refiner anode assembly.
