Abstract
The object of the present invention is to provide such a vitrification treatment method of aluminum and filter radioactive waste: developing glass frit required for vitrification of aluminum and filter radioactive waste and proper mixing of aluminum and filter radioactive waste and glass frit , so as to develop the oxide composition distribution of aluminum and filter radioactive waste with a viscosity of 100 poise or less for maintaining the operating parameters of the furnace, thereby producing a high-quality vitrified body to solidify the vitrified glass as the final product of vitrification The body complies with relevant laws and regulations. In order to achieve the above object, the method of vitrification of aluminum and filter radioactive waste is characterized in that aluminum, filter radioactive waste and glass frit are mixed in an induction heating type low-temperature melting furnace, melted at 1100°C to 1200°C, and vitrified to form a glass solidified body.
Description
Vitrification method of aluminum and filter radioactive waste technical field The present invention relates to a vitrification treatment method of aluminum and filter radioactive waste, in particular to a vitrification treatment method of aluminum and filter radioactive waste as follows: developed in the air conditioning system (HVAC) of nuclear power plants and atomic furnace facilities Treatment of pollutants, glass frit required for vitrification of aluminum and filter radioactive waste generated using CCIM, derivation of aluminum and filtration for mixing with glass frit for maintaining suitable melt viscosity The amount of radioactive waste added to the glass can be used to deduce the oxide composition range of the formed aluminum and filter radioactive waste, thereby trapping the pollutants in the glass structure and preventing the aluminum and filter radioactive waste from being discharged to the outside. Background technique Typically, low and intermediate level ra...
