Experimentation, modeling, and analysis of the dissolution of chloride salt beads in aqueous solvents (pure H2O, ERDA-6, and GSEEP) were conducted to provide fundamental information in support of evaluating the feasibility of directly disposing electrorefiner waste salt. Currently the waste salt is immobilized by a ceramic waste form and stored. Direct disposal of the waste salt could provide time and cost efficiencies. Dissolution tests involved LiCl-KCl eutectic, LiCl, SrCl2, CeCl3, LaCl3, PrCl3, and YCl3 as solutes at 20 °C. Bead diameter was measured and recorded at intervals while submerged in the aqueous solvent. The change in the diameter of the bead was found to be linear in time and the applied model exhibited a good fit with R2 > 0.94. Initial results indicated that dissolution was faster in water than in the brines. Further results will be presented and discussed.
