It is a medium-sized tokamak with high magnetic field (Bt = 5 T) and high temperature vessel (< 500 °C). Hence, large electromagnetic forces are expected on the Passive Stabilizing Plates (PSP) and Vacuum Vessel (VV) during plasma disruption events. A non-selfconsistent approach is selected for the electromagnetic calculations using ANSYS Maxwell software to determine the highest probable forces on passive structures and to design a robust vacuum vessel. This paper outlines the latest status on the design activities of the vacuum vessel concept and its mechanical verification against the electromagnetic forces. The vessel design concept is developed considering the spatial constraints, fabrication simplicity, minimum cost and the design is verified for minimum deformation and stresses in the vessel. It also includes the design evolution of PSP, PSP support and VV support. The mechanical analyses are carried out for load combinations of plasma transient events.
