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 effect of reducing the aspect ratio on the confinement of deuterium-tritium fusion products, i.e., alpha particles, in tokamaks is discussed. It is shown that for low-aspect-ratio tokamak reactors, the alpha-particle heating efficiency can be similar to conventional tokamaks; at the same time, the alpha-particle confinement time can be much shorter than that of conventional tokamaks. Thus, one can facilitate alpha-particle ash removal while maintaining high alpha-particle heating efficiency by reducing the aspect ratio.
