摘要
In this study both electric heating and fluid heating were proposed to bakeout the port plug structure being inserted in the middle of the international thermonuclear experimental reactor （ITER） vacuum vessel. The coupled thermal and structural analyses were carried out. The results, such as the distributions of the temperature field, thermal stress and thermal deformation of the port plug, were obtained. Based on the American Society of Mechanical Engineers （ASME） criteria, the reliability and feasibility of the heating technique were verified. The results provide detailed information on the selection of a preferable method for future engineering experiments.
