摘要： PROBLEM TO BE SOLVED: To provide a method for immobilizing radioactive waste while securing the loading weight equivalent to that in the case of low viscosity even if viscosity heightens because of the disparity in the viscosity of a mixture of radioactive waste consisting of powder or pellets mainly composed of sodium sulfate and immobilizing materials.
SOLUTION: The water 7 in which sodium hydrogencarbonate is dissolved is mixed with a radioactive waste 4 before adding an immobilizing material, loaded with the immobilizing material such as cement, mixing them, and immobilized. As the viscosity is curbed to a fraction of that in the absence of loading with sodium hydrogencarbonate, a large quantity of waste can be filled into a drum 5 of 200 L, an immobilizing container.

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 processing method for radioactive waste using electrolyte containing Ag2+ which can reduce the amount of spent ion exchanger material. SOLUTION: By contacting nitric acid solution containing Ag2+ with U, Pu and Np having adhered to a filter in a reaction tank 1, these elements are solved in the nitric acid solution by the Ag2+ effects. In a cathode chamber 7 wherein a cathode 9 of the main electrolysis tank 2 is placed, the Ag2+ in nitric acid solution containing the solved elements is reduced to Ag+. These elements are removed from the nitric acid solution exhausted from the cathode chamber 7 by the ion exchanger material in an ion exchanger tower 3. In an anode chamber 6 wherein an anode 8 of the main electrolysis tank 2 is placed, the Ag+ contained in the nitric acid solution is oxidized to Ag2+. As removal amount of Ag2+ by the ion exchanger material can be drastically reduced, the life of ion exchanger material is extended and thus the generation amount of spent ion exchanger material is drastically reduced.
