Alumina and alkali binders for cementing liquid radioactive wastes, which include boric acid compound were compared. Given the need for long-term keeping of insulating properties of the matrix at waste disposal as a condition of providing environmentally sound localization of conditioned waste residue, more promising is the use of alkaline binders. Comparison was made of alumina and alkali binders for cementing of liquid radioactive wastes, which include boric acid compound. Keywords: liquid radioactive waste, bottoms, nuclear power plant, cementing, binding materials.
