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.

The once-through mode of steam generator reflux condensation in the presence of noncondensable gases and/or aerosols in loss-of-coolant accident scenarios is introduced. The plausible severe accident scenarios associated with once-through reflux condensation are analyzed with MELCOR to demonstrate the background and safety significance of this phenomenon. An analytical model for once-through reflux condensation with noncondensables inside one single U-tube is developed using the heat and mass transfer analogy approach. The conditions for partial condensation inside the single U-tube can be determined with this model. The progress of modification to the ARTIST test facility to experimentally study the tube-to-tube nonuniform behavior of once-through reflux condensation inside a U-tube bundle is reported.
