| Research Achievements | Development of the Integrated engineering analysis platform of DEMO divertor through electromagnetic-structure coupled analysis | |
|---|---|---|
| Research Overview | - By developing an environment capable of electromagnetic-structure coupling analysis, the electromagnetic force generated in the divertor during the DEMO plasma disruption and the resulting deformation and stress were evaluated. | |
| Research Contents | - Develop an integrated analysis environment that can evaluate the structural integrity of the divertor by calculating the electromagnetic force generated during the DEMO plasma disruption for various scenarios using ANSYS Emag Solver and applying this force to structural analysis | |
| Major Research Achievements | - Electromagnetic forces were evaluated for 6 types of MD (Major Disruption) and VDE (Vertical Displacement Events), which are representative plasma disruption scenarios of the DEMO, structural analysis was performed according to each scenario, and a coupling analysis environment was developed. | |
| Expected Effects | - Through the developed integrated analysis environment, it is expected to be used for evaluating the electromagnetic force and structural integrity of various major parts such as the blanket and vacuum vessel as well as the divertor of the DEMO. | |
