FIELD: radiochemical industry, particularly foam dispersion or prevention by addition of chemical substances.
SUBSTANCE: foam formation is reduced by introducing antifoaming agent in reaction medium, wherein the antifoaming agent is previously solved in nitric acid. The antifoaming agent is organic compositions of ethylene and propylene oxides block copolymer class.
EFFECT: reduced foam formation during aluminum-containing fuel elements solution in nitric acid.
