Preliminary dynamic analysis of the forces on the COMPASS-U tokamak foundations

Popis výsledku v původním jazyce

The COMPASS-U tokamak (Bt = 5 T, Ip = 2 MA, R = 0.894 m, a = 0.27 m) is currently under design at IPP CAS (Institute of Plasma Physics of the Czech Academy of Sciences). One of the design challenges is to design sufficiently strong foundations to support even the highest forces that are generated during plasma disruption events. The worst, found up to now, scenario has been considered in order to simulate the response of the main tokamak components and to calculate the force transmitted to the foundations. A 3D model has been built in the ANSYS Workbench software including the cryostat support, the vacuum vessel, the poloidal field coils and their supports. The forces have been calculated via global electromagnetic model. Integrated values of the forces and torques have been spread onto surfaces of the parts. The modal superposition method has been utilized for the integration, based on the first 100 vibration modes. Rayleigh damping model with the fraction of critical damping of 2% was used. The reaction forces transmitted to the foundations have been obtained providing input for the civil design work.
