IMPROVEMENTS IN METHODS OF SOLIDIFYING WATERY ATOMIC WASTE
In the method described radioactive waste water is introduced without stirring into a finely divided hydraulic binder contained in a mold, the mixture thus formed is allowed to set hydraulically, and the block is subjected to a finishing treatment for increasing its resistance against lixiviation and atmospheric and mechanical influences. The hydraulic binder may consist of a refractory cement either alone or together with suitable aggregates in a granular condition. The waste water may be introduced into the binder by tubes suspended in the mold. The tubes have a funnel-like upper end, apertures at fixed distances along their length, and are open at the lower end. The finishing treatment may consist of baking in an oven after the block has set or introducing an impregnating material through the tube used to insert the waste water. The impregnating materials may consist of water-repellent substances in a melted condition or in the form of solutions in a volatile organic solvent or emulsions, for example, liquid selfhardening synthetic resins such as casting resins or paraffin, lacquers, synthetic fat-amino or silicone compounds.
