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 slowing down density, q, of neutrons in a reactor may be decomposed into a sum of parts due to various nuclear species having corresponding scattering cross sections µs1, µs2, ···. An approximate relation between qi and isotropic flux φ(u) (where u is the lethargy) is proposed. . The values of γi and ξi are derived and interpreted.
