Evaluation of Electromechanical Loads in the Vacuum Vessel of a Single-Turn Ignition Tokamak

A detailed evaluation of the electromechanical force distributions in the vacuum vessel of the IGNITEX device during major plasma disruptions is presented. The effects of the disruption plasma conditions, the single-turn toroidal magnet system, and the vessel resistivity are discussed. The electromechanical stresses are evaluated and stress distributions are presented. It is shown that the electromechanical forces due to plasma paramagnatism are comparable to the usual forces due to the plasma toroidal current. The stress analysis is performed for the proposed IGNITEX vacuum vessel.
