A method of solidifying radioactive incombustible solid wastes

Purpose: To enable to prepare solidified products with no deleterious pores and least free water content as possible while avoiding the problem of secondary wastes treatment. Method: Cement mortar or paste with an addition of a mixing agent for the improvement of fluidity is injected into a vessel containing radioactive incombustible solid wastes and the mortar or paste is filled in the gap of wastes and solidified by applying vibrations to the vessel. Thus, when the radioactive incombustible solid wastes are solidified with cement in accordance with the solidification processes, contained in a drum can or like other vessel can be solidified as they are with no requirement for a mixer, etc. Accordingly, no installation cost is required and there is no problems such as processing of washing water.
