Solution for Nuclear Radiation Shield Seal and Performance Analysis of Metal Bellows

Solution for the nuclear shield seal is put forward. Seal mechanism and feasibility of the swaying metal bellows type shield seal technology is expounded. The finite element model of metal bellows used in shield seal was set up,using finite element analysis software,to obtain the stress distribution in the bellows under operation condition,and to analyze the parameters which affects the performance of the shield seal.
