增殖包层作为中国聚变工程实验堆(China Fusion Engineering Test Reactor, CFETR)的核心部件,承载着能量转换和氚增殖的重要作用。中国科学院等离子体物理研究所在之前增殖包层设计的基础上,又提出了氦冷陶瓷增殖(Helium Cooled Ceramic Breeder, HCCB)包层的概念设计。为评估电磁载荷对HCCB包层结构安全性的影响,借助通用有限元软件ANSYS,研究计算了在等离子体主破裂时包层中产生的感应涡流、洛伦兹力和力矩。通过多物理场耦合分析方法,获取了包层中产生的等效应力和形变位移。结果表明,在等离子体电流指数衰减时,HCCB包层模型上产生的最大等效应力和形变位移满足包层结构设计的要求,同时模拟分析结果也为未来的包层结构优化以及支撑结构设计提供了必要的数据支撑。 |

Background: As the core components in the fusion reactor, the breeder blanker takes the role of tritium breeding and energy conversion. A helium-cooled ceramic breeder(HCCB) blanket concept has been put forward for the China fusion engineering test reactor(CFETR) by the blanket integration design team of the Institute of Plasma Physics of Chinese Academy of Sciences. Purpose: The aim is to study the influence of the electromagnetic(EM) transients on the structural design of HCCB breeder blanket. Methods: The eddy current, Lorentz forces and moments are calculated by the transient analysis. The maximum equivalent stress and deformation displacement generated in the components under extreme conditions are obtained by coupling calculation of multi-physical field. Results: The eddy current induced by the EM transients, Lorentz forces, moments, the maximum equivalent stress and deformation displacement generated in the components are obtained by ANSYS. Conclusion: The results show that the maximum equivalent stress and displacement of deformation are satisfied with the requirement of structural safety design. Moreover, this simulation will provide the necessary reference data for future design and optimization support structure of the HCCB breeder blanket. |
