| titleOfInvention | Method to immobilise radioactive wastes in mineral-like matrix |
| abstract | FIELD: power engineering. n SUBSTANCE: invention relates to processing of liquid radioactive wastes (LRW), mostly, nitrate ones, containing alkaline and alkali-earth elements, also salts of sodium, radio isotopes 137 Cs and 90 Sr. The method to immobilise radioactive wastes in a mineral-like matrix includes synthesis of mineral with high content of radioactive elements and mixing particles of the radioactive mineral with a filler in a glass-like condition, consisting of stable materials, with subsequent thermal treatment of produced charge at high temperatures. Synthesis of the mineral and mixing with the filler are carried out simultaneously, and the mineral producing agent and the filler are cenospheres from fly ashes from coal burning, which are mixed with solution of radioactive wastes in the specified ratio, afterwards the cenosphere-water mixture is evaporated to produce a cenosphere-salt composition, which is exposed to calcination at the temperature of 750-1100°C within the specified time to produce a glass crystalline material that contains mineral-like phases-fixators of radio nuclides. n EFFECT: simplification and reduction of energy intensity of hardening process of liquid LRW in the form of mineral-like ceramics. n 4 cl, 2 dwg, 4 ex |
