The PST is a lower aspect ratio tokamak that aims to do research on the nuclear fusion science and technology. The PST pressure vessel, as a nuclear pressure vessel, is one of the key components of fusion reactor. This study using CATIA for pressure vessel structural design, while utilizing ANSYS for pressure vessel structural parameter optimization analysis. The electromagnetic-thermal-mechanical coupling effect research is systematically addressed to improve safety margins while ensuring plasma operation stability. The research results of this article can provide theoretical and engineering references for the commercialization of compact fusion reactors in the future.
