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 pulsed source method has been used to measure the thermal neutron diffusion parameters of zircaloy-2 hydride whose approximate composition is ZrH1.7. The asymptotic decay constant (zeroth energy eigenvalue) has been measured for the buckling range 0.03 < B2 < 0.39 cm−2 and has been fitted by a polynomial containing terms to B8. The first energy eigenvalue has been measured over the range 0.05 < B < 0.39 cm−2 and has been used to estimate the thermalization time constant. In addition the thermalization time constant has also been determined from time dependent transmission measurements with 1 /υ absorbers.
