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 margin to criticality of selected distorted core configurations derived from the hypothetical loss of shutdown cooling accident in a 300-MW(electric) gas-cooled fast reactor has been investigated using two-dimensional transport theory. Configurations representing crumbled cores, declad fuel columns in nearly intact geometry, and partial slumping of the fuel on the core floor with subsequent radial spreading have been studied. Three minimum postulated conditions for re-criticality have been identified for the configurations characterized by declad fuel in nearly intact geometry:
