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.

An autoclave and a water treatment and monitoring system simulating the secondary side of a steam generator are used to investigate the hideout phenomena of sodium chloride in a tube-support-plate crevice. The primary-side heating tube is simulated by an internal heater. The experiments are performed at 1 atm pressure. The effects of heat flux, bulk concentration, crevice width, and the presence of a porous medium are investigated. It is found that the solute concentrates heavily near the upper end of the crevice. This concentration distribution in the axial direction is confirmed by a model developed in a parallel study. The hideout rate increases with increasing heat flux and bulk concentration. The concentration level in the crevice at a given time increases with increasing heat flux and bulk concentration and with decreasing crevice width. The presence of a porous medium in the crevice significantly enhances the concentration effect.
