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.

As an initial step toward a comprehensive fuel management procedure, a model was developed to optimize fuel loading patterns in pressurized water reactors (PWR) with regard to a specified function of burnup and power. For this purpose, the JUMBO code employs a simplified semianalytic function to represent X-Y power distribution and a direct search scheme to optimize shuffling. The number of feasible patterns is greatly reduced through the use of a logical set of shuffling rules. The applicability of the method was demonstrated for a typical 500-MW(e) PWR, considering both an initial and reload core.
