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 failure to obtain agreement between the calculated and measured reflector savings in the Fast Exponential Experiment led to a study of the processes involved in obtaining spectral equilibrium in small, highly enriched systems. It was shown that the length of the equilibrium region was a sensitive function of the pedestal thickness and could be optimized for this assembly. Factors which were found to be significant are, as expected, the geometry and the spectrum of the source. Both the experimental results and the theoretically derived results are presented. The methods of collecting data and the methods of data analyses which proved most fruitful are also presented.
