Chemical Treatment Laboratory

The chemical treatment is the process used for the treatment of aqueous liquid radioactive waste of CDTN, and aims to reduce the waste volume for cementation. In the process, the radionuclides, and other contaminants present in the waste, are precipitated/co-precipitated, as hydroxides, carbonates, sulfates and phosphates. The formed slurry is separated by decantation and incorporated into cement. The supernatant is filtered, analyzed and released if below the disposal threshold. All stages of the treatment are monitored by means of laboratory tests aiming a greater efficiency of treatment and quality control of the final product.
