Solidification of 30% TBP-OK Waste by Calcium Sulfoaluminate Cement

Abstract:

Liquid organic radioactive waste is one kind of wastes from the use of radioisotopes in research centres, medical and industrial applications and also in nuclear power plants. Effective management of these liquid organic wastes is necessary in order to ensure their safe handling, processing, storage and disposal. Cementation for Tri-N-Butyl Phosphate/Odorless Kerosene (TBP/OK) solvents was studied. Emulsifiers were selected and compared. Calcium sulfoaluminate cement (SAC) was used in TBP/OK solidification. A prescription containing 20% (v/v) TBP/OK was obtained. And the compressive stretch is above 10MPa. The leach rates of Sr²⁺, Cs⁺, Co²⁺were studied. Monolithic solids were formed.
