Abstract

Abstract: A 1GW fusion power reversed shear (RS) scenario is designed for CFETR steady state operation using the fast integrated modelling tool, METIS. This RS scenario is maintained by 40MW off-axis electron cyclotron current driving (ECCD) and 40 MW neutral beam current driving (NBCD). In this scenario, the steady safety factor profile has a minimal q, q_min=3.1 at ρ=0.52. Therefore, the dangerous m/n=3/2, 2/1, 5/3 NTM (neoclassical tearing mode) would be avoid. The influence of Argon atom fraction in plasma on the performance of this RS scenario is also analyzed.

Key words: CFETR, Steady-state operation, Integrated simulation, Reversed shear scenario, METIS

摘要： 采用快速集成模拟软件 METIS 完成了 CFETR 1GW 稳态反剪切运行模式的设计。该反剪切运行模式由 40MW 离轴电子回旋电流驱动(ECCD)与 60MW 的离轴中性束电流驱动(NBCD)所实现，获得了稳定的安全因子剖面，其在 ρ=0.52 处具有最小安全因子 q_min=3.1，从而可避免危险的 m/n=2/1、3/2、5/3 的新经典撕裂模(NTM)。此外，本文还分析了 Ar 杂质粒子的含量对此稳态反剪切模式约束性能的影响。
