Structural Design and Force Analysis for Equatorial Diagnostic Port Plug of ITER

摘要

The structural design of equatorial diagnostic port plug for international thermonu-clear experimental reactor(ITER)was discussed in this paper.The induced electromagnetic(EM)loads of port plug and blanket shielding module(BSM)were presented.The finite element anal-ysis(FEA)and numerical calculation of the system were performed under the maximum loads.According to the American Society of Mechanical Engineers(ASME)criteria,the EM stress isfar below the admissible failure boundary,which indicates that the system can resist the cooper-ative action of EM loads and device deadweight.The analysis could provide technical data andreferences for further analysis and optimized design of the system.
