Abstract
PURPOSE:To considerably reduce volume without using heating material by taking out radioactive waste liquid containing sodium sulfate as solidified materials of calcium sulfate containing radioactive substances. CONSTITUTION:Calcium oxide (CaO) or calcium hydroxide (Ca(OH2)) is added, mixed and agitated in radioactive waste liquid containing sodium sulfate produced in a nuclear power plant. Heating treatment is performed, and solid and liquid are separated from each other if necessary. Solid deposited substances after solid and liquid are separated from each other is calcium sulfate (CaSO4) in which the greater part of radiated materials such as Fe, Cr, Co, Mn is included, and kept as it is or forming material is mixed to solidify as after-treatment, heated and made into anhydrous salt and solidified so as to adsorb water. The liquid is sodium hydroxide (NaOH) solution to use again or used to separate alkali metal such as Cs. Therefore, the danger of a fire is eliminated, the volume of production of solidified materials can be reduced and economical efficiency can also be improved.
