摘要： PROBLEM TO BE SOLVED: To provide a solidification disposal method for a radioactive waste provided with a procedure for determining within a proper range an amount of an alkaline earth metal compound and a material/compounding of a curing agent added to a radioactive waste liquid containing sulfate ion or the radioactive waste containing a soluble sulfate compound to bring a pH of water contacting with a solidified body into 12 or less and to bring a sulfate ion concentration into 200ppm or less.
SOLUTION: The alkaline earth metal compound 7 is added to the radioactive waste in a drum can 4 to bring a molar amount of alkaline earth metal into 1.0 or more with respect to a molar amount of the sulfate ion contained in the radioactive waste, so as to prepare a mixture of a sulfate of a solidlike alkaline earth metal and a solution containing an alkali metal ion, and a silicon oxide compound 8 and blast furnace water granulation slag and/or fly ash 9 are added as the curing agent to the mixture to bring a molar amount into 1.2 or more with respect to a molar amount of the alkali metal contained in the radioactive waste, and is stirred by a stirrer 5 to be solidified.

摘要： PROBLEM TO BE SOLVED: To provide a solidification treatment method of radioactive effluent for rapidly and accurately determining an optimum amount of added chemical even if the concentration of sodium sulfate changes tank by tank/with every effluent collection.
SOLUTION: While controlling the liquid level by means of a sensor 102, the effluent in a tank 100 is put into a solidification container 101 by a determinate volume to find its weight by an instrument 103. The weight and the put-in volume are used to calculate the density of the effluent. A prescribed graph is referred to to estimate the concentration of sodium sulfate corresponding to the calculated density. Barium hydroxide whose volume corresponds to the estimated concentration of sulfuric acid is added from a tank 104 to a tank 100, thereby insolubilizing the sulfuric acid. In the process of insolubilization treatment, barium hydroxide is inputted in the sulfuric acid, which is kept at 60°C or more, and its effluent is kneaded. Since a solution after the insolubilization shows high pH, silicic acid which is a major constituent of silica fume is added thereto for reaction from a tank 105, thereby synthesizing sodium silicate (water glass) which is a solidifying material.

摘要翻译：要解决的问题：为了提供放射性流出物的凝固处理方法，即使硫酸钠的浓度通过罐/每个流出物收集罐改变罐，也可快速和准确地确定添加的化学品的最佳量。解决方案：在通过传感器102控制液面的同时，将罐100中的流出物以一定的体积放入固化容器101中，以通过仪器103找到其重量。重量和放入体积用于计算流出物的密度。参考规定的图表来估计对应于计算密度的硫酸钠浓度。将体积对应于硫酸的估计浓度的氢氧化钡从罐104加入到罐100中，从而使硫酸不溶解。在不溶解处理的过程中，将氢氧化钡输入到保持在60℃以上的硫酸中，其流出物被捏合。由于不溶解后的溶液显示高pH，所以加入作为硅灰的主要成分的硅酸从罐105反应，从而合成作为凝固材料的硅酸钠（水玻璃）。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To efficiently solidify radioactive waste liquid containing sodium sulfate without allowing unreacting sulfate ions to remain therein, thereby obtaining a solidified body having high water resistance and extremely little affecting a buried artificial barrier.
SOLUTION: In this radioactive waste liquid solidification method for solidifying radioactive waste liquid containing sodium sulfate, solidification procedure is divided into an insolubilization process for insolubilizing sulfate ions in the waste liquid while heating the waste liquid and a solidification process for solidifying the insolubilized waste liquid. Temperature variation is measured accompanying endothermic reaction of the waste liquid in the insolubilization process. Completion of the solidification process is determined based on the transition of temperature. After the completion of insolubilization, heating electric power is reduced and switching takes place to the solidification process (turning into water glass → polymerization solidification).

摘要： PROBLEM TO BE SOLVED: To provide a method for treating radioactive effluent solidification for making a solidified body employing an in-drum method and by solidifying a radioactive effluent containing sodium sulfate and having high radioactive concentration, wherein a solution resulting after the solid body is immersed in water that has a pH of 12 and a sulfate ion concentration that is not higher than a mortar equilibrium concentration.
SOLUTION: Barium hydroxide 5 is added to a radioactive effluent 1 containing sodium sulfate so that the content of barium hydroxide becomes equivalent to or higher than the content of sodium sulfate in terms of mol, and a silicon oxide compound 6 and a water reducing agent 7 are added to a mixture of barium sulfate and an aqueous alkali solution, thus obtained, and are kneaded to produce water glass. A hardener 8 is added to a mixture of the water glass produced and barium sulfate prior to being subjected to the kneading and solidification treatment. A viscosity enabling solidification treatment by in-drum method can be obtained, by controlling a water/powder ratio and the quantity of the water reducing agent 7, wherein the ratio of total water/(total of silicon oxide compound 6 and hardener 8) is defined as the water/power ratio.
