Abstract

Abstract: HL-2M tokamak vacuum vessel (VV) is designed with a D-shaped, double thin-wall structure. The
whole torus is welded with 20 sectors and is supported by 5 trunnions locating in the equatorial plane to absorb
thermal displacement at the baking. There are 121 ports to meet the demands of pumping、diagnosis、heating and
installing. Inconel 625 is selected as the main material of the VV. Design analyses have be done. The results show
that vacuum vessel structure can meet the design requirements of the machine.
