Abstract

It has been shown experimentally that it is possible to convert hydroxide precipitates containing radioactive isotopes into a chemically stable glass mass, which satisfies the requirements for safe !ong-time storage. A study has been made of the way in which the chemical stability of the glass mass is affected by composition as well as by temperature and radiation effects. The optimum comrosition of the charge, and the temperature and time of melting have been found for producing a glass naa,~ having satisfactory chemical stability. It has been shown that prolonged annealing of the glass mass in the temperature range 350–900° C lowers its chemical stability in an acid medium, due to the formation of a crystalline phase. Additional irradiation during annealing makes the crystallization more extensive, without affecting the temperature range,
