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.

Recycle of nitric acid in the UREX+ process requires removal of acetic acid. An analysis of the effects of acetic acid in each process step indicates no step will be significantly affected by the concentrations expected. Thus, acetic acid removal can be placed after the last salts are removed, just before the nitric acid is recycled. Two promising removal options have been considered, solvent extraction and distillation. Distillation requires removal of most of the water before large fractions of acetic acid are removed. The process would be energy intensive and would involve the handling of extremely concentrated nitric acid; therefore, solvent extraction appears to be more attractive.
