采用托卡马克模拟程序（TSC）模拟了实验用先进超导托卡马克破坏放电的完整演化过程。调整了异常输运系数的乘数，以模拟以61 916弹丸为基础的双零导流器配置的主要破坏流量。采用等离子体位移实时反馈控制系统。对极向场线圈电流、等离子体电流、主半径、等离子体结构演变的模拟结果与实验测量结果一致。模拟结果表明，在中断过程中，约有8 MW m−2的热流流到上导流器目标板，约有6 MW m−2的热流流到下导流器目标板。计算结果表明，通过调整异常输运系数的乘数，可以产生不同的导流器靶板上的热流通量。这表明TSC具有很高的灵活性和可预测性。
The tokamak simulation code (TSC) is employed to simulate the complete evolution of a disruptive discharge in the experimental advanced superconducting tokamak. The multiplication factor of the anomalous transport coefficient was adjusted to model the major disruptive discharge with double-null divertor configuration based on shot 61 916. The real-time feed-back control system for the plasma displacement was employed. Modeling results of the evolution of the poloidal field coil currents, the plasma current, the major radius, the plasma configuration all show agreement with experimental measurements. Results from the simulation show that during disruption, heat flux about 8 MW m−2 flows to the upper divertor target plate and about 6 MW m−2 flows to the lower divertor target plate. Computations predict that different amounts of heat fluxes on the divertor target plate could result by adjusting the multiplication factor of the anomalous transport coefficient. This shows that TSC has high flexibility and predictability.
