Constituent analysis of metal and metal oxide in reduced SIMFuel using bromine-ethyl acetate

2018 
We demonstrated that bromine in ethyl acetate can selectively separate metallic contents in lanthanide metal-oxide mixtures for analysis, which had been validated for uranium. This Br2-EtOAc dissolution method was applied to determine the constituents of metal and metal oxide in SIMFuel that was electrochemically reduced from oxide fuel in the molten salt. Compared with the analysis results obtained after dissolving the fuel in an acid solution, we concluded that the Br2-EtOAc method can be applied to uranium and rare earths but not to noble metals for the reduction yield determination.
