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.

Two models for criticality wave systems are presented, distinguished by the coolant flow direction with respect to the wave propagation direction, namely, an upstream wave (UW) model and a downstream wave (DW) model. It is shown that in the DW case the reactor power and wave velocity are considerably lower than those in the UW case, but the burnup is much higher.
