本文基于中国固态实验包层模块(CN HCCB-TBM)优化设计,应用ANSYS软件参数化语言编程方法,对中国固态TBM在ITER等离子体两种主破裂事故下的电磁载荷进行了评估与分析,并利用分析结果进行了电磁-结构和电磁-热的耦合计算。研究结果表明中国固态TBM的更新结构设计在等离子体瞬态变化中符合安全设计要求。

Electromagnetic analysis on China HCCB-TBM design under major disruption

Under two major disruptions of ITER Plasma the electromagnetic loads on the updated design of CN HCCB-TBM have been performed by using ANSYS Parametric Design Language. The stress and temperature analyses have been obtained by applying multi-physical fields’ calculations such as magnet-structure and magnet-heat coupling in this paper. The results showed that the maximum stress is ~26.2MPa, which was as low as the allowable value of RAFM(CLF-1). Due to the interaction of eddy current and resistance the Joule heat caused the temperature of TBM to rise to ~0.1K, which had less influence to the thermo-hydraulic design of TBM. The evaluations of EM loads on TBM have been showed that the updated structural design of TBM was safe which can overcome the EM loads brought by two kinds of major disruptions.
