Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

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.
