Electromagnetic analysis of transient disruption forces on the ITER shield modules

The effect of paramagnetic shift during thermal quench on internal components in fusion devices

“…Because the poloidal currents induced in the vacuum vessel and other internal components will cause large forces, it is important to accurately simulate the induced current in complex 3D structures. The OPERA code has the capability of performing transient electromagnetic (EM) simulations with complex 3D conducting structures [4,5]. In order to simulate the change in toroidal field, we constructed a shell conductor the shape of the last closed flux surface that carried current in the poloidal direction (see Fig.…”

Computational study of the electromagnetic forces and torques on different ITER first wall designs

“…They include 6 central solenoid coils, 6 poloidal field coils, and an axial current (to simulate the toroidal field coil) [2]. The plasma currents are modeled by 100 loops that vary with timeequivalent to the plasma current in the DINA simulations.…”

Electromagnetic analysis of forces and torques on the ITER shield modules due to plasma disruption

“…They include 6 central solenoid coils, 6 poloidal field coils, and an axial current (to simulate the toroidal field coil) [3]. The plasma currents are modeled by 100 loops with currents that vary with time but are stationary in space -equivalent to the plasma current in the DINA simulations.…”
