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.

In this work, experimental and mathematical substantiation of the possibility of using the new RCTU-4 hydrophobic catalyst [0.9 mass % Pt/styrene and divinylbenzene (SDVB)] in the separation of protium-tritium isotopic mixtures by a two-temperature catalytic exchange method in a water-hydrogen system was carried out. Variation of the synthesis parameters of the support and the catalyst allowed a significant increase in the activity (≥50 s–1) and heat resistance (≈550 K) of the investigated sample compared to the previously used catalyst RCTU-3SM (kexp = 12 s−1; heat resistance = 388 K). The mathematical model presented in the paper considers three phases (liquid water, steam, and hydrogen gas) and allows optimization of dual-temperature installations in the water-hydrogen system for any isotopic mixtures.
