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.

Plutonium and fission product migration were studied in a low burnup vibrationally compacted UO2-2 wt% PuO2 specimen utilizing autoradiography, micro sampling, microgamma scanning, and shielded electron microprobe analytical techniques. The results show that a significant change in radial plutonium concentration can occur rapidly in high performance mixed-oxide fuels by a vapor transport mechanism that is coincident with the fuel restructuring phenomenon. This results from the condensation of uranium-rich vapor in the cooler peripheral regions of the fuel rod. Cesium, ruthenium, and rhodium migrate significantly in mixed-oxide fuels, whereas zirconium, niobium, cerium, and praseodymium do not redistribute significantly.
