The ACTIVA system has been developed to adsorb radioactive nuclear wastes by 99.53% under
pH-controlled conditions, and to vitrify them below 1,150ºC in the melter for immobilizing
radioactive sources (Cs-137 and Co-60), providing advantages as follows:
- The capacity of solidification at relatively low temperature
- Low viscosity of the molten glass
- Moderate electric conductivity
- Meeting the requirement of US DOE Product Consistency Test
- Low ACTIVA loading
- Excellent homogeneity of the glass
- Simple process of vitrification
