Description
The ramp up scenario design, which considers of both physics and engineering constrains, plays an important part in fusion device design. The Tokamak Simulation Code (TSC), coupling with some auxiliary heating codes, has been implemented in the CFETR system code to construct the workflow of the CFETR ramp up scenario designs. In this workflow, the CFETR geometric construction design and some preliminary physics parameters are firstly prepared as the input of the 1.5D TSC computation. Then different discharge scheme are obtained by TSC with coupling the poloidal field systems controller with passive structure, free boundary equilibrium solvers and the auxiliary heating sources. The electron cyclotron (EC) and neutral beam (NB) sources are used to heat the plasma and drive the toroidal plasma current form the output of ONETWO code. Based on the time-dependent plasma current density distribution evolutions simulated by TSC, ANSYS is used to analysis the 3D electromagnetic loads and stresses in the main structural components, which are used to estimate the safety operation of CFETR. In this presentation, some scenarios with different ramp rates or heating schemes are also presented.
