Description

The consolidation of salt in flowing brine was studied under uniaxial stress and the results correlated using a model. Adsorption of such ions as Cs(I), Sr(II), Eu(III), and I- on such earth materials as clays or Al2O3 is being studied. Molten-salt processes are being investigated for separating components of high-level wastes; separation of Pd from Ru and complexes formed by NbCl5 in chloro-aluminate melts were studied. Adsorption of actinides (Am,Np) on geological media is being studied. Lanthanide orthophosphates are being synthesized and studied (EPR, Raman,absorption, Moessbauer spctra) as possible alternatives to glass as actinide waste forms. 18 figures
