In order to ensure the long-term safety of the vitrified radioactive waste, the relationship between number of stirring and characteristics of material strength after melting the raw material glass and simulated vitrified radioactive waste were investigated by synchrotron radiation X-rays. As a result, it was clarified that the internal defects in simulated vitrified radioactive waste increased and the material strength of simulated vitrified radioactive waste was suitable as increasing the number of stirrings.
