Abstract

The densities of various Zirflex-type solutions at 25 gas-cooled C can be expressed by the equation: p calc = (0.99710 + 0.03l57 m) + (0.02046 - 0.002659 m)c -(0.0033460.000703 m)c3/2 + 0.14349x + 0.49z where m = moles liter/ sup -1/ NH/sub 4/NO/sub 3/, c = moles liter/sup -1/ NH/sub 4/F, x = moles liter/ sup -1/ (NH/sub 4/)/sub 2/ZrF/sub 6/, and z = moles liter/sup -1/ UO/sub 2/(NO/ sub 3/)/sub 2/. This eq uation fits the data with a sigma value of 0.00018 g/ml for NH/sub 4/FNH/sub 4/NO/sub 3/ solutions, 0.00024 g/ml for NH/sub 4/F-(NH/sub 4/ )/sub 2/ZrF/sub 6/ solutions, and 0.0002 g/ml for solutions containing UO/sub 2/ (NO/sub 3/)/sub 2/ and/or NH/sub 4/F-NH/sub 4/NO/sub 3/ over the range of 0.0M to 6.0M NH/sub 4/F, 0.0M to 1.6M NH/sub 4/NO/sub 3/, 0.0M to 0.5M (NH/sub 4/)/sub 2/ ZrF/sub 6/, and 0.0M to 0.0025M UO/sub 2/(NO/sub 3/)/sub 2/.
