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.

Measured neutron noise and thermocouple noise spectra from two commercial pressurized water reactors are presented. The noise spectra from both reactors show similar trends with core burnup, and the moderator temperature coefficient of reactivity can be predicted by calculating the frequency response function between the in-core neutron flux and the core-exit coolant temperature.
