Beschreibung
Zusammenfassung:	FIELD: radioactive waste disposal. ^ SUBSTANCE: immobilization of liquid radioactive waste comprises preparing solution of radioactive waste with liquid glass-forming additive and organic reducer solution followed by introducing the two solutions into melter to melt glass. Liquid boron-containing glass-forming additive is prepared from solid sodium tetraborate Na2B4O7*xH2O (x=0-10) and boric acid or from their mixture and solution of organic reducer, in particular 1,20ethanediol or 1,2,3-propanetriol. ^ EFFECT: increased radioactive waste fixation reliability. ^ 6 cl, 2 tbl, 3 ex
