A study of the solubility relations among some of the fission products in a fuel mixture was carried out. Fluorides such as those of Ce/sup 141/, La/ sup 140/, Sm/sup 153/, Y/sup 91/, and Ba/sup 133/ were used with NaF--ZrF/sub 4/- UF/sub 4/ fuel solution Experimental procedure is described and data are tabulated. The data reveal that fission product precipitation in NaF- ZrF/sub 4/- UF/sub 4/ is not a reactor problem. Reasonable estimates of the solubility of other rare earths can be made from a consideration of the atomic radii of those investigated. The chemical feasibility of solid-solvent extraction of rare-earth poisons from the molten fluoride fuel was also established. (J.R.D.)
