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.

By extrapolating the experimental laws describing the energy confinement and the magnetohydrodynamic stability limits in current large tokamaks, it can be shown that stable thermonuclear ignition equilibria should exist in this type of configuration if the product of dimensions multiplied by a power of the magnetic field intensity is large enough. By quantitatively applying this result to several next-generation tokamaks, it appears that such equilibria could exist in these machines. Moreover, the additional heating power that will be available in these devices should be sufficient for ignition.
