Partitioning and transmutation (P and T) of the long lived nuclides in spent nuclear fuel into short-lived ones is an important step in decreasing the radiotoxicity, volume, and time necessary for storage in a repository. A proper separation of the metals used in the transmutation process is necessary and solvent extraction with different ligands is one of the possibilities. This separation has been extensively tested in Europe using the BTP and BTBP class ligands. In this paper a comparative study of the extraction capabilities of CyMe{sub 4}-BTP and CyMe{sub 4}-BTBP as function of different diluents and kinetics has been made. (authors)
