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 the Federal Republic of Germany, hightemperature gas-cooled reactor (HTGR) operating experience with the experimental Arbeitsgemeinschaft Versuchsreaktor (AVR) and the thorium high-temperature reactor (THTR)-300 prototype plant forms the basis for follow-up medium HTGR concepts for electricity production and small modular designs for combined electricity and heat production. To some degree, plant designs emphasize inherent safety features. Basically, this ensures that beyonddesign-basis events, including total loss of forced cooling, do not cause a large (catastrophic) activity release or, in the case of the small modular concept, any significant release. Assessments based on intensive experimental and theoretical work indicate a minimum risk for either plant. Acute protective countermeasures (e.g., evacuation) will not be required; only for the (nonoptimized) medium-sized concept could long-term relocation and decontamination be appropriate for a relatively small area.
