A joint exists in mechanical structure. The material used according to the use environment is also various for mechanical structure. The reliability is requested of the technology to which those are joined. Laser machining doesn't choose the material. It's expected that this is used as variety material junction technique and necessary welding technique. It's necessary to consider influence of a stress by the variety organization of the joint neighborhood, the mechanical property and the difference in the heat expansion coefficient between the variety metal together. To aim at generalization by this TAKUMI's technological calculation scientific simulation, permanent deformation spacial distribution inside the same kind material weld material between the carbon steel, the carbon steel and the variety material weld material of oxygen-free copper by a high powered fiber laser was measured and the special quality about the processing influence was estimated.

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.

High level radioactive vitrified materials are subject to monitoring during decades at storage facilities and over tens of thousands of years at final disposal sites. Although sufficient structural stability for long-term storage is necessary, high effluent filling which is often incompatible with mechanical and chemical integrity are required. The inhomogeneity of the glass yielded in preparation will cause the instability of the glass. Residual stress is one of the important parameters for evaluating the stability of the vitrified materials. Conventional stress measurement using a strain gauge reveal the averaged stress of whole specimen, however, local stress is also important because it can be an origin of the deformation or crack. Therefore, we developed a method using high-energy synchrotron X-ray stress measurements to clarify the local strain of the vitrified materials. Moreover, stress of each structural component such as crystalline and glass matrix can be separated by the method.
