Glassy radioactive waste is a promising method for treating radioactive waste. Many kinds of elements are confined in the glass raw material. To stablish technology of confirm the stability for vitrified substances is required. We developed an analytical method for residual stress in vitrified radioactive waste samples using the analyzing from synchrotron-ray diffraction and scattering profile. We are studying application to various vitrified radioactive waste samples. We hope that this measurement method will be one of the methods for contributing to the solvation of vitrification technology.
