FIELD: recovery of liquid radioactive wastes. ^ SUBSTANCE: proposed method includes calcination of concentrate of transuranium and rare-earth elements in environment of ceramic-forming flong. Used as ceramic-forming flong is concentrated solution of chromium nitrate or concentrated solution of chromium nitrate doped with concentrated solution of copper nitrate in proportions required to form solid solutions of M1 - xCuxCrO3, where M are transuranium and rare-earth elements; x = 0 0.20. Calcinate is compacted in the open using hot isostatic pressing method. ^ EFFECT: enhanced reliability of ceramic immobilization of radioactive wastes. ^ 1 cl, 2 tbl, 2 ex |
