Method for producing settling type mud water and method for recovering fuel debris

摘要

In addition, it is possible to shield radiation in a high temperature environment and α Problem to be solved: to provide a method for producing settling type mud water capable of removing fuel debris without causing any problem of scattering of nuclides, and a method for recovering a fuel debris using this settling type mud water.The present invention is characterized in that it is composed of a process of adding a precipitated barium sulfate to the water by stirring the precipitated barium sulfate to the water, and adding the addition of a sulfuric acid barium sulfate to the water obtained in the step of adding the precipitated barium sulfate to further stir the barium sulfate.Diagram
