Abstract

The HL-2M tokamak is an upgraded device of the HL-2A tokamak. As one of the main components of the HL-2M, the vacuum vessel (VV) is required to have a reliable structure and be manufactured with well-established methods. The HL-2M VV is designed with a D-shaped cross section, double-thin-wall structure that consists of the inner shell, outer shell, ribs, and ports. The whole torus is welded with 20 sectors. Inconel 625 has been selected as the main material of the VV because of its good mechanical properties and high resistivity. The structural analysis is performed using ANSYS. The results show that the VV can meet the design requirements. The manufacturing process of the VV is described in detail. The VV was completed in March 2019, and the HL-2M device achieved its first plasma discharge in December 2020.

HL-2M真空容器的设计与制造

摘要

HL-2M托卡马克是HL-2A托卡马克的升级版。作为 HL-2M 的主要部件之一,真空容器 (VV) 需要具有可靠的结构并采用成熟的方法制造。HL-2M VV设计为D形横截面,双薄壁结构,由内壳、外壳、加强筋和端口组成。整个环面由20个扇区焊接而成。Inconel 625因其良好的机械性能和高电阻率而被选为VV的主要材料。使用ANSYS进行结构分析。结果表明,VV能够满足设计要求。详细描述了 VV 的制造过程。VV于2019年3月完成,HL-2M装置于2020年12月实现首次等离子放电。
