This article presents the evaluation of vitirification behavior of simulated high-level radioactive wastes from the reprocessing of spent nuclear fuels with borosilicate glassesdeveloped for the high-loading of wastes, and dissolution conditions of wastes in the glass. In-situ on-heating process and rate-cooled vitirifcied glasses were examined, and summarized with the results of the combinatorial approach to find glass matrixes with high-loading capacity.
