FIELD: concentration of liquid radioactive wastes by evaporation. SUBSTANCE: process of concentration by evaporation involves injection of liquid radioactive wastes in glycerin, waste-to-glycerin ratio within evaporation zone being 1:9 to 1:1. Measures are taken to prevent encrustation of heating surfaces by salt deposits and local corrosion on stainless steel. EFFECT: facilitated handling of bottoms, enhanced evaporation degree. 2 cl, 1 dwg, 3 tbl
