Keywords:ADS, Beam window, LBE, Thermal stress analysis, Nonlinear buckling analysis

The results of nonlinear buckling analysis considering external stress by LBE and thermal stress under high temperature environment for beam window which is one of the most important tasks in design study of accelerator driven transmutation system (ADS) are summarized. By coupled analysis (Heat flow structure etc.), beam window design condition (beam thickness, beam window radius, etc.) which is more feasible than before are obtained.
