Mechanical and Critical Study of a New Fuel Assembly Container

The mechanical and critical calculation methods used in the design process of a new fuel container were introduced in this paper.Based on the design laws and regulations,the mechanical simulation was carried out,which including stacking performance computing in the limiting condition,modal analysis and fatigue failure calculation under the road transportation.At last,the single and array critical calculation of the new design container in different work conditions were carried out.The results mentioned above offered references for the container detailed design.
