Abstract
Third phase formation during nuclear solvent extraction has the delirious effect on operation of extractor cascade and may result in the criticality due to unsafe accumulation of the actinides. In this study, the nitric acid third phase was generated with 30%TBP-dodecane/nitric acid system and characterization studies were performed. The earlier model of author and coworker for U(IV) and Pu(IV) third phase could be extended to cover the current study. Experimental results indicated a presence of chain-linked nitric acid dimer to a single molecule of TBP in the generated nitric acid third phase whereas speciation in the light phase was similar to unpartitioned organic phase.
