An advanced PUREX process has been developed which can reduce TRU waste volume and the environmental hazard risk due to long-lived nuclides. The separation of neptunium and technetium from plutonium and uranium solutions has been studied before the U/Pu partitioning step in the PUREX process. The effectiveness of normal-butyraldehyde as a reductant of Np(VI) to Np(V) and of high acid scrubbing of technetium was shown in a basic study and a chemical flowsheet study.
