Title:
放射性核種を含む溶液を予備浄化する方法
Document Type and Number:
Japanese Patent JP7043458
Kind Code:
B2
Abstract:
FIELD: nuclear power industry.SUBSTANCE: invention relates to a method for pre-purification of solutions containing radionuclides, such as Co-60, such as cubic residues of nuclear plants, by precipitation of inactive nuclides in a hydrothermal process and subsequent separation of precipitated solids. A method for removing radionuclide complexes, in particular EDTA-Co-60 complexes, from solutions, such as cubic residues of nuclear plants, includes pre-purification of the solution by precipitation of at least inactive nuclides in the hydrothermal process to prevent the destruction of at least Co-60 complexes and subsequent separation of solids precipitated in pre-purification and subsequent destruction of at least Co-60 complexes and separation of Co-60.EFFECT: invention makes it possible to reduce the proportion of inactive nuclides in the solution, from which radionuclides are then separated.12 cl, 1 dwg
