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.

Both PF1A upper coils and lower coils experienced difficult situations during the National Spherical Torus Experiment–Upgrade (NSTX-U) machine operations in 2016. There are huge up-down electromagnetic forces on PF1A terminals, coil leads, and bus bars. Therefore, further analysis and additional reinforcement supports are needed to reduce the stress on the coil terminals and leads. Structural, thermal, and electromagnetic analyses of the three-dimensional PF1A lower bus bar and coil lead model have been performed using imported electromagnetic loads with the worst cases of 96 scenarios through the global Biot-Savart stick model. The reinforcement blocks for the PF1A lower coil leads and flags and two clamps were analyzed and installed for field testing. The coil leads and bus bars used in the field testing were qualified for the normal NSTX-U operating loads allowing similar reinforcement details to be used in the real NSTX-U machine.
