Abstract
The Water Cooled Ceramic Breeder (WCCB) blanket is one of the blanket candidates for Chinese Fusion Engineering Test Reactor (CFETR). To investigate the electromagnetic (EM) force (magnetization force and Lorentz force) on the WCCB blanket, EM analyses were carried out using ANSYS Multiphysics code. At first, finite element (FE) static magnetic analysis under normal operation condition was accomplished, adopting the magnetic scalar potential (MSP) method. The magnetization force can be obtained as a result. Then transient magnetic analysis under plasma disruption event was performed using the magnetic vector potential (MVP) method. The eddy current on blankets was subsequently analyzed. Finally, the Lorentz force applied on blankets can be calculated with cross-product of the eddy current field from transient magnetic analysis and the magnetic field from the static magnetic analysis. The EM forces will be used as mechanical loads for the future structural analysis of blanket under integrated load.
