METHOD FOR RECOVERY OF LIQUID ACID RADIOACTIVE WASTES Russian patent published in 2003 - IPC

Abstract RU 2201630 C2

FIELD: case-hardening liquid radioactive wastes including spent sulfuric cationite reclaimed products. SUBSTANCE: method includes neutralization and mixing of mentioned reclaimed products with binder in the form of alumina cement and mineral sorption additive in the form of clay. Neutralization is conducted by binder just during mixing of mentioned ingredients. Mass proportion of cationite reclaimed products, alumina cement, and clay is 1 : (0.75-1.00) : (0.07-0.10). Method provides for better fill-up of solidified products concerning liquid sulfuric radioactive wastes. EFFECT: reduced volume of wastes being disposed at their sufficient strength and water resistance. 1 tbl, 7 ex
