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 Greuling-Goertzel approximation is applied to the calculation of neutron slowing down in heavy water in the B1 and P1 approximations. Numerical calculations of the flux and nonescape probability assuming constant cross sections indicate the “inconsistent” G-G B1 approximation to be the most favorable. Existing machine codes can readily be modified to this method.
