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 Boltzmann-Fokker-Planck equation has been applied to treat charged-particle slowing down in solids. The discrete ordinates (SN) methods, with exact kernels (I*) or traditional truncated Legendre expansions (SNPL), have been used to investigate well-defined benchmark problems related to atomic displacement cascades. For an overall higher accuracy, it is found that an exact kernel transport calculation is equivalent, in terms of CPU cost, to a SNPN approach in one spatial dimension. Moreover, if the related cross-section processing methods are compared, it is shown that the calculation of the scattering kernels needed by the I* method requires only as much CPU time as the standard P0 matrix evaluation.
