Specification of asymmetric VDE loads of the ITER tokamak

Effects of asymmetric vertical disruptions on ITER components

“…3.4, some parameters of interest for the considered VDE are shown. The 2D plasma evolution has been computed by using the DINA numerical code [2,6,12]. The PF coil current waveforms have been prescribed as calculated by DINA.…”

Dynamic response of the ITER tokamak during asymmetric VDEs

“…The possible asymmetric VDE loads on the ITER tokamak have been described in detail in [2,3], with a summary published in [4]. This paper concerns itself with Category III VDEs, which can be defined by their direction (up or down), their asymmetry (TPF) and their rotational frequency (in Hz).…”

Analytical model of wall forces produced by kink perturbations in tokamaks

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] Evaluations for ITER give worrisome numbers at the level of hundred MN. [12][13][14][15][16][17][18][19][20][21] There are several approaches [2][3][4][5]7,9,17,19,[21][22][23][24] to calculating the instability-induced electromagnetic forces on the vessel components in tokamaks, but some issues remain unresolved. 13,20 One of them was recently raised in Refs.…”

“…It is known [2][3][4][5]7,8,[10][11][12][13][14][15][16][17]20,22,[33][34][35][36][37] that the force on the wall during the disruptions in tokamaks depends on the halo current, which is the part of the plasma current that flows in the conducting structure and has a return path through the plasma. 14,15,22,33,34 In Ref.…”

“…(2) we can apply the results to the cases like asymmetric vertical displacement events (AVDEs) [3][4][5]12 though without a halo current.…”
