... Thermophysical and thermochemical data on aqueous solutions of hydroxyurea is scarce. Recently, Kumar et al. [7] listed few properties of aqueous hydroxyurea solutions like density, apparent molal volume, vapour pressure and thermodynamic water activity values, which were derived from in-house experiments. ...
Hydroxyurea and its derivatives are important nonsalt forming reductants in partitioning of uranium and plutonium in the nuclear fuel reprocessing operations. There is no experimental data available in open literature describing pressurization due to the thermal decomposition of aqueous and nitric solutions of hydroxyurea at elevated temperatures. Authors studied thermal decomposition of hydroxyurea-nitric acid system and resultant pressurization at various concentrations of nitric acid in an adiabatic calorimeter in closed-vent conditions. During these experiments, pressurization was observed. In this paper, results of these experiments have been discussed.
