description <p/> <p>We conducted reversed deliquescence experiments in saturated NaCl–NaNO<sub>3</sub>–H<sub>2</sub>O, KNO<sub>3</sub>–NaNO<sub>3</sub>–H<sub>2</sub>O, and NaCl–KNO<sub>3</sub>–H<sub>2</sub>O systems from 90 to 120°C as a function of relative humidity and solution composition. NaCl, NaNO<sub>3</sub>, and KNO<sub>3 </sub>represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository environment at Yucca Mountain, NV. Discrepancy between model prediction and experiment can be as high as 8% for relative humidity and 50% for dissolved ion concentration. The discrepancy is attributed primarily to the use of 25°C models for Cl–NO<sub>3 </sub>and K–NO<sub>3 </sub>ion interactions in the current Yucca Mountain Project high-temperature Pitzer model to describe the nonideal behavior of these highly concentrated solutions.</p>
