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.

Xenon spatial oscillation may give rise to operational difficulties in a nuclear power plant. In this study, in order to investigate xenon instability for a pressurized water reactor, the frequency-domain technique is adopted by using the generalized Nyquist criterion, which is more general and suitable for the multi-input /multi-output system. Also linearized modal fluxes are obtained by modal expansion. This model has been implemented to test the axial xenon stability of the KNU 7 unit with changes in plant operating parameters.
