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.

Simulated high-level liquid waste was irradiated by 60Co gamma radiation, and changes in the gas-phase concentrations of the products H2, O2, and NOx that accumulated in the absence of sweeping air were measured. The H2 concentration reached a steady-state value of much less than 4% in line with the value predicted from the previously derived mathematical expression. The simulated dissolver solution was also irradiated, and another steady-state H2 concentration of much less than 4% was obtained in accordance with the corresponding predicted value. These experimental results lend strong support for the applicability of a mathematical expression in predicting the H2 concentration in a tank in the case of a sweeping-air function loss.
