FIELD: power industry. ^ SUBSTANCE: fixation method of radioactive cesium isotopes at heat treatment of radioactive wastes (RW) involves preparation of the charge containing graphite, including 14C isotope, titanium dioxide, thermit mixture, as well as up to 25 wt % RW. Charge is mixed, loaded to tight reactor or container; above the main layer of charge there placed is additional layer of natural zirconium isotope with thickness of 1/6 thickness of the main charge layer or oxide of natural isotopes of silicon, titanium, aluminium and iron, with thickness of 1/5 to 1/3 of thickness of the main charge layer; and charge is heat treated. ^ EFFECT: possibility of performing high-temperature heat treatment of multi-component mixtures containing high-active RW including graphite-containing RW, with complete fixation of cesium evaporating during mixture heat treatment. ^ 2 cl, 3 ex |
