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 Impurity Processing (IP) system is designed to recover tritium from tritiated compounds (Q2O, CxQy, NQ3, with Q = H, D, T and x>=1, y>=4) collected from the JET torus or generated during the processing of gases inside the Active Gas Handling System (AGHS). The recovery process involves dilution of the impurities in helium, addition of oxygen, recirculation of the helium-impurities-oxygen mixture over a hot recombiner (773K) to generate water and CO2, and trapping of the water on 160K cold surfaces. The remaining gas species He, CO2, O2, N2 (with a very small tritium concentration) are transferred finally to the Exhaust Detritiation (ED) system for further reduction of the tritium concentration by at least a factor of 1000. The cold trap is heated (473K) and the water vapour passed over two hot iron beds at 823K to “crack” the water. The recovered hydrogen isotopes are stored in cold uranium beds (U-beds) for further processing in AGHS.
