Abstract

Abstract The supercritical CO2 cOoled Lithium-Lead (COOL) blanket has been designed as one advanced blanket candidate for the Chinese Fusion Engineering Test Reactor (CFETR). This paper focuses on the electromagnetic (EM) loads (Maxwell force and Lorentz force) acting on the COOL blanket, which are important mechanical loads in further structural analysis of the COOL blanket. In this study, a 3D electromagnetic analysis is performed using ANSYS finite element method to obtain EM force on the COOL blanket. Firstly, the magnetic scalar potential (MSP) method is used to obtain the magnetic field distribution and the Maxwell force on the COOL blanket. Then, the magnetic vector potential (MVP) method is performed during a plasma disruption event to get the eddy current distribution. At last, a multi-step method is adopted for the calculation of the Lorentz force and the torque. The maximum Lorentz force of inboard and outboard blanket structural components is 4968kN and 1786kN respectively.

CFETR冷毯的初步电磁分析

超临界CO2冷却锂铅(COOL)包层是中国聚变工程试验堆(CFETR)的一种先进候选包层。本文重点研究了作用在冷毯上的电磁载荷(麦克斯韦力和洛伦兹力)，这是进一步分析冷毯结构的重要力学载荷。本文采用ANSYS有限元法对冷毯进行了三维电磁分析，得到了冷毯上的电磁力。首先，利用磁标量势(MSP)法获得了COOL毡层上的磁场分布和麦克斯韦力;然后，在等离子体破坏过程中，利用磁矢量电位(MVP)方法得到涡流分布。最后，采用多步法计算了洛伦兹力和转矩。内外包层结构构件的最大洛伦兹力分别为4968kN和1786kN。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
