Abstract (en)
[origin: WO2013010564A1] The invention relates to a method for conditioning liquid radioactive waste, in which, in order to prepare the batch, a sorbent is introduced into the liquid waste and the waste is then separated. The method is characterised in that a hydrophobic carbon sorbent is used and, once this has been introduced into the waste, the solid phase is milled until a particle size of µm is obtained. Once the powder has been dried, this is subsequently pressed into a briquette which is granulated to form grains (globules) and these granules are treated with a microplasma in the processing area while being constantly stirred, in order for the separation to take place. Following this, the gaseous products undergo a "cold oxidation of hydrogen", while the solid sediment of the radioactive components is pressed into briquettes.
