Abstrakt: Radiolytic gas formation was measured in aqueous alkali–nitrate and alkali–nitrate–aluminate solutions simulating liquid intermediate-level wastes. The radiation-chemical yields of the gas mixture and its individual components depending on solution composition and irradiation temperature (up to 60°C) were determined. It was noted that oxygen was formed in comparatively high yields (up to ∼0.4 and ∼0.6 molecule/100 eV in alkali–nitrate–aluminate solutions at 30 and 60°C, respectively). This fact was explained by the decomposition of hydrogen peroxide, which is formed as a primary product of water radiolysis and in the combination of O radical ions, and by the catalytic effect of aluminate ions.
