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.

A model has been developed for calculating critically safe storage configurations of cylindrical vessels containing aqueous solutions of UO2F2 (93.2% 235U) and Pu(NO3)4 (95% 239Pu and 5% 240Pu). The method deals with square lattice arrays of cylindrical vessels in air surrounded by concrete walls. This model uses the concepts of surface density and unit surface -to -volume ratio to define safe array parameters. Important factors that influence this storage model are the shape of the individual storage units, storage room height, storage vessel wall thickness, and the effects of body reflection of personnel among the storage vessels. Accidental solution spills in the form of thin slabs of solution on the floor of an array also strongly influence the array parameter, surface density, and, consequently, storage or processing facility capacity.
