The electrometallurgical technology under development at ANL is derived from many years of research and development on molten salt systems for the production of materials for nuclear reactors and weapons as well as from activities in battery development. This technology for treating DOE’s SNF consists of several unit operations:
Head-end treatment, including fuel disassembly and steps such as oxide reduction, if required;
Treatment of effluent electrorefining streams, including the ceramic and metal waste forms produced by this electrorefining, and processing of the uranium deposited at the steel cathode.
It is the technological aspects of these operations that the Committee on Electrometallurgical Techniques for DOE Spent Fuel Treatment has evaluated in the course of its work from 1995 to the present.
