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 even-order spherical-harmonics theory for cylindrical geometry is developed along the same lines previously utilized for slab geometry. In particular an ‘effective boundary moment’ is found such that the common spherical-harmonics approach can be straightforwardly applied. The disadvantage-factor problem for a cylindrical unit cell is utilized to show the inherent countervergence of the odd- and even-order results when utilized in this manner. An extrapolation procedure is suggested to overcome the difficulty of divergence for small unit-cell sizes.
