在第一个概念设计活动中，JT-60SA TF系统的总体设计被定义，并在项目所有参与者（CEA， ENEA, F4E）的同意下冻结，随后必须启动第二阶段来处理详细设计。在本文中，我们介绍了CEA在第二阶段对TF线圈设计所做的工作。这项工作的一部分，是关于在运行和工厂中导体水力性能的测定。还对导体的热水力进行了评估，以确定是否需要氦气入口，并开发了一种特定的设计，并通过认证，使其与低温装置的可用水力性能相兼容。力学性能仍有待评估和鉴定。最后但并非最不重要的是，为了简化制造过程，相对于CEA为ITER线圈开发的原始双箱设计，线圈的内部电气接头进行了修改。一个专门的制造资格认证程序正在进行中。
Following a first conceptual design activity in which the general design of the JT-60SA TF system was defined and frozen in agreement with all the participants in the project (CEA, ENEA, F4E), a second phase had to be launched to deal with the detailed design. In this paper, we present the work performed at CEA on the TF coil design during this second phase. Part of this work, concerns the determination of conductor hydraulic performances during operation as well as in factory. The thermohydraulic of the conductor was also assessed to confirm the need of helium inlets and a specific design was developed and qualified to be compatible with the available hydraulic performance of the cryoplant. The mechanical behavior is still to be assessed and qualified. Last but not least, the inner electrical joints of the coil have been modified with respect to the original twin-box design developed by CEA for the ITER coils in order to simplify the fabrication process. A dedicated qualification program for their manufacture is ongoing.
