摘要：
The structural chemical changes in the high-temperature contact zone of 08Kh18N10 (AISI 304H) steel and the melts of model sodium-cesium aluminoborosilicate matrix materials containing alkaline-earth element additives are studied in terms of the development of methods for highly active radioactive waste immobilization using their vitrification and storage in metallic containers (cans). The dissolution and nonuniform distribution of the steel components in the borosilicate melt and the formation (near the steel surface) of thin layers of metallic nickel and iron-chromium spinel providing the protection of the containers from further corrosion are established.
