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.

In this accuracy study, we have solved with the discrete S2, S4, and S8 approximations a monoenergetic half-space problem with a delta-function pencil of neutrons as a source and compared the values of four suitable integral quantities with the results of Monte Carlo calculations. The errors in the space-dependent integrated neutron flux are shown in several figures. Also, tests with different mesh resolutions of the iteration net and with different standard quadrature sets have been made.
