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.

Erbium oxide (Er2O3) coating layer is one of the suitable coatings to realize an advanced breeding blanket system because it has high electrical resistivity and hydrogen permeation suppression effect. In order to enhance these properties of Er2O3 coating, it is necessary to form a thick coating layer with high crystallinity. The formation of a double stacked coating layer on an austenitic stainless steel 316 substrate using an intermediate layer (buffer layer) was investigated for the thicker and high crystallinity of Er2O3 coating formation. Yttrium oxide (Y2O3) and cerium oxide (CeO2) were selected as buffer layer between the Er2O3 layer and austenitic stainless steel 316 substrate due to their similar lattice constant to that of Er2O3 crystal. The texture and grain growth direction of Er2O3 was controlled by the Y2O3 and CeO2 buffer layer. However, the suppression effect of hydrogen permeation by the double stacked coating was smaller than that of the single layer coating due to the thin Er2O3 formation.
