Argonne National Laboratory (ANL), along with other national laboratories, has been developing a solvent extraction process for partitioning of spent fuel constituents to lead to safer and cheaper disposal of high-level waste. The process, known as UREX+, separates key radionuclides from dissolved spent fuel into: (1) uranium for disposal as LLW, (2) technetium for disposal as HLW, (3) iodine f...
