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 effect of a mixing vane was studied in a three-subchannel geometry for a 3.99-mm (0.157-in.) gap space, and for mass velocities of 339.0, 678.1, and 1356.2 kg/s⋅m2 (0.25, 0.50, and 1.0 Mlb/h⋅ft2, respectively). Mixing rates increased rapidly downstream of the vane and then decreased gradually as a function of downstream distance. The maximum increase in turbulent cross-flow for a mass velocity of 339.0 kg/s⋅m2 occurred ∼10 hydraulic diameters from the end of the mixing vane and was 150% greater than the value observed at comparable conditions for the same test section without a mixing vane. The average increase in mixing due to the presence of the vane was ∼58%.
