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.

Recently developed methods for separation and analysis of radioactive fission gases have been applied to obtain data for an off-gas system of an in-pile loop. A separate in-pile test facility was designed to provide a gas transport stream having fission products having concentrations simulating those anticipated in the off-gas system. Characterization of the radioactivities in this facility provided necessary pre-operational information and specifications for operational and analytical procedures for the off-gas system test.
