Abstract Uranium solubility in aluminosilicate melts of the Na2O-CaO-Al2O3-SiO2 system with two different Na/Ca ratios was studied at temperatures of 1250–1400°C and under various redox conditions. A closed thermochemical reactor was used to control the alkali metal activity (sodium oxide content) and the oxygen fugacity imposing the reducing environment on the glass melt (10−5 atm
