Development of ramp up design workflow on CFETR Integrated Design Platform
2017
Abstract The ramp up scenario design, which considers of both physics and engineering constrains, plays an important part in fusion device design. A workflow of ramp up design, which includes Tokamak Simulation Code (TSC), ONETWO and ANSYS, has been developed on CFETR Integrated Design Platform. According to the 0-D design, the 1.5 D code TSC is used to build a ramp up scenario describing all parameters evolutions, targeting the design goals and attempting to remain in all constrains. In TSC simulation, the deposited power and driven current of auxiliary heating are calculated by ONETWO. The plasma current and PF coil currents are then used as input of ANSYS, to analysis the 3D eddy current and electromagnetic force in the main structural components. An example case of CFETR ramp up, with ohmic heating during the current ramp up phase and 57 MW of neutral beam and 10 MW of electron cyclotron at the flattop, is given in this article to show the function of the workflow. Under the unified environment for both physics and engineering design provided by CFETR integrated design platform, the present workflow will make the ramp up design more efficient.
