中国聚变工程试验堆（CFETR）是一座处于初步设计阶段的新型托卡马克聚变反应堆，其环向场（TF）线圈的设计磁场超过14.3T。TF导体需要在14.3 T下稳定运行，需要尽可能地排除热和电磁负载引起的导体性能退化。最大洛伦兹力将达到1200 kN m−1，远高于ITER导体。在以前的研究中，发现在电磁循环和预热-冷却循环期间性能下降。导体的退化和它的机械性能之间的相关性被发现。根据分析，具有短捻距（STP）方案或铜缠绕超导股线（CWS）设计的导体具有大的刚度，这使得在电磁和热负载循环方面的性能显著改善。电缆刚度与导体内部股间接触点的数量密切相关。基于这一概念，四种类型的原型电缆导管导体样品与STP和CWS设计制造。分析了股线间接触点的数量，并在77 K下进行了机械横向载荷测试。结果表明，单位长度上接触点越多的导体刚度越大。然而，设计成具有高索刚度的索引起股线压痕，这也被调查。本文讨论了导体设计和实验结果，并与ITER TF和中心螺线管导体进行了比较。
The China Fusion Engineering Test Reactor (CFETR) is a new tokamak fusion reactor under preliminary design, where the toroidal field (TF) coil has been designed to create a magnetic field of over 14.3 T. The TF conductors need to operate stably at 14.3 T, requiring the exclusion of conductor performance degradation from thermal and electromagnetic loading as much as possible. The maximum Lorentz force will reach about 1200 kN m−1, which is much higher than that of ITER conductors. In previous research, performance degradation was found during electromagnetic cycles and warm-up–cool-down cycles. A correlation was found between a conductor’s degradation and its mechanical properties. According to the analysis, a conductor with a short twist pitch (STP) scheme or a copper wound superconducting strand (CWS) design has large stiffness, which enables significant performance improvement in terms of the electromagnetic and thermal load cycling. The cable stiffness is closely related to the number of inter-strand contact points inside the conductor. Based on this concept, four types of prototype cable-in-conduit conductor samples with STP and CWS design were manufactured. The number of inter-strand contact points was analyzed, and mechanical transverse load testing was performed at 77 K. The results show that the conductors with more contact points per unit length exhibit a higher stiffness. However, the cable designed with high cable stiffness caused strand indentation, which was also investigated. In this paper, the conductor design and experimental results are discussed and compared with ITER TF and central solenoid conductors.
