Barney, G. S.

Phase equilibria of the seven-component system, NaOH-NaNO/sub 3/-NaNO/sub 2/-NaAlO/sub 2/-Na/sub 2/SO/sub 4/-Na/sub 2/CO/sub 3/-H/sub 2/O, were studied. This system simulates radioactive sodium salt wastes stored in underground tanks at Hanford. Equilibrium water vapor pressure of the aqueous phase and solubility of the salts were measured as a function of temperature and NaOH concentration. These data are used to predict deliquescence of stored salt wastes and also to predict the chemical identity of solid residues from evaporation of liquid wastes.
