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.

Ideal gas and multiphase flow through porous soil surrounding a nuclear power generating station after a core meltdown accident are analyzed with dimensionless variables. Results are applicable to many soil conditions. The extent of radioactive fluid penetration into the soil, predicted using methods originally developed by Morrison, indicates that years are required for activity to reach the ground surface if silty clays are present but only ∼ 10 h if a path of sand is included. Source pressure decay caused by mass flow into the soil is small if the normal conditions of a large containment shell volume and low soil permeability exist.
