Effect of thermal annealing on the properties of borobasalt systems containing simulated radioactive waste from pyroelectrochemical technology

详细

The effect of thermal annealing performed in the temperature range 400–800°С on the hydrolytic durability of borobasalt systems containing simulated radioactive waste from pyroelectrochemical technology was studied. Three types of simulated waste were examined: type 1, waste from reprocessing of reactor-grade plutonium; type 2, waste from reprocessing of weapons-grade plutonium; type 3, waste from gallium recovery from type 2 waste (virtually pure americium phosphate). Depending on the waste type and temperature, annealing can both increase and decrease the host material leach rate.
