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 CN method of solving the transport equation is applied to one-velocity classical problems in cylindrical geometry. The cylindrical angular Green's function is calculated first, the inner and outer albedo problems are solved, and numerical results are obtained and compared with reference results. The extrapolation length for the cylindrical Milne problem is calculated, and accurate results are presented. Finally, the determination of the critical radius for multiplying media is treated.
