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.

Many computer codes are based on subchannel analysis, which is important for thermal-hydraulic analysis of the reactor core. Most of these codes make some assumptions to determine the axial velocity in the gap region (AVGR), but no real arguments have been given to justify these assumptions. A new way to determine the AVGR between two parallel single-phase flows that communicate by a lateral slot has been successfully incorporated in Tapucu’s subchannel analysis experiments.
