Abstract
FIELD: recovery of liquid radioactive wastes of nuclear power plants and radiochemical integrated factories. SUBSTANCE: method involves mixing of liquid radioactive wastes with ceramics former, nitrate-anion reducer, and mineralizer, mixture dewatering to residual moisture content not over 10% at not over 100 C, stage-by-stage heating of dewatered mixture from 100 to 900 C, calcination at 900 C, and cooling down of ceramics-like material obtains. EFFECT: provision for preventing emission of toxic nitrous gases, improved safety of process and improved quality of product, facilitated procedure. 4 cl
