Vertical displacement event/disruption electromagnetic analysis for the ITER-FEAT vacuum vessel and in-vessel components

N Miki, M Verrecchia, P Barabaschi, A Belov, Y Utin2001年Fusion Engineering and DesignIF 1.7出版社

AbstractThis paper summarises the preliminary results of the electromagnetic (EM) analyses for ITER vacuum vessel and in-vessel components, such as blanket and divertor modules. Two disruption scenarios are taken into account: plasma centered disruption, and vertical displacement event (VDE). Eddy currents and forces due to VDE/disruption were calculated using the 3D shell element code TYPHOON and the 3D solid element code EMAS and ANSYS. The plasma motion and current decay used in the EM analysis has been supplied by 2D axisymmetric plasma equilibrium codes, MAXFEA. The EM loads in the blanket module are reduced by deep poloidal and radial slits.

要約:本論文は、ITERの真空容器およびブランケットやダイバータモジュールなどの容器内コンポーネントに対する電磁(EM)解析の予備的結果をまとめたものである。2つのディスラプションシナリオが考慮されている:プラズマ中心ディスラプションと垂直変位イベント(VDE)である。VDE/ディスラプションによる渦電流と電磁力は、3次元シェル要素コードTYPHOONと3次元ソリッド要素コードEMASおよびANSYSを用いて計算された。EM解析に用いられたプラズマの運動と電流減衰は、2次元軸対称プラズマ平衡コードMAXFEAによって供給された。ブランケットモジュールにおける電磁荷重は、深いポロイダルスリットとラジアルスリットによって低減される。
