Description

This proposal focuses on the following basic objectives to generate critical information for the following research Needs: (a) to conduct spectroscopic speciation of uranium compounds in glass forming melts as a function of the acid-base composition of the glasses and melt temperatures, and to use these data to develop a general thermodynamic model for the dissolution of actinide species in oxidic glass matrices, (b) to build a scientific basis for a new methodology to measure the basicity of glasses via optical spectra of in-situ immobilized actinides and to use this optical basicity as a primary actinide structure indicator for solid ... continued below
