    Abstract: 用過核燃料的最終處置方式,國際間對此一課題進行許多評估與研究,深地層處置(deep geologic disposal)被認為是最安全可行的處理措施。
    ;There are many international studying and evaluation about the abject.
    Considering of safety, technology and economy, the method of deep geologic disposal is regarded as the most safety and stable way.
    In this study, based upon the concept of the deep disposal method, thinking about the thermal, hydrological and mechanical properties of the paper in Sweden. In addition of considering the size of repository, initial condition and boundary condition of the internal paper.
    The study directed at the influences of the saturation histories on the thermal conductivity of buffer material, to make the scoping analyses. In the results, the maximum temperature in the repository has obvious change due to the saturation histories.
    In this study, using Taiwan Power Company report. Choosing its exploration data and disposal field size, using finite element method and 3D model to analysis. Thermal stress analysis adopt sequentially coupled thermal-stress analysis. Because Taiwan is located in the earthquake zone, the earthquake may create weak band in the top of disposal field. This research will focus on the effect of weak band’s size.
    In this study, when the weak band’s size increases, the horizontal stress on the disposal site will increase. And when the weak band occurs, the water flow of the disposal site will increase.
