The research results of {alpha}-radionuclide behavior during inclusion of simulated HLLW in the various types of glass matrices (phosphate and boron-silicate compositions) are submitted at present paper. The conducted investigations of uranium, plutonium-239 and americium-241 behavior show, that the uranium participates in formation of glass matrix structural skeletons but distributions of plutonium and americium in volume of solidified materials depend on compositions of used HLLW and chosen matrices, as well as conditions of technological process of vitrification. The plutonium solubility levels, plutonium and americium distributions in volume of glass logs, compositions of heterogeneous phases forming in melts on the basis of HLLW components and valence conditions of dissolved uranium are determined by using of {alpha}-radiography, {gamma}-spectrometry, x-ray phase and other methods of analysis. The results of conducted researches indicate the limited solubilities of studied radionuclides in phosphate and boron-silicate glasses.
