Solidification & stabilization

Solidification and stabilization (S/S) technology is used for the management and disposal of a broad range of hazardous wastes, including radioactive wastes. Solidification refers to the mechanism that binds the hazardous material and transforms it into a solid block, whereas stabilization refers to the chemical changes of the hazardous material, which transform it into a less soluble, mobile, or toxic form.

The S/S treatment involves mixing a binding agent into the contaminated media or waste. This binding agent usually consists in a combination of cementing materials and chemical additives that is specific to the hazardous waste to be solidified and stabilized. The objective of the Solidification & Stabilization group is the development of optimum binding agents for the long-term storage of radioactive wastes in term of strength, durability characteristics and chemical stability.
