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 simplistic analytical treatment is given of the effects of dislocations and solid fission products on the behavior of fission gas in oxide fuel elements during fast thermal transients. The analysis is coupled with the BUBE code (a code that models equilibrium and nonequilibrium fission gas bubbles in thermal transients) and used to analyze two Transient Reactor Test Facility transients. The results suggest that the effect of dislocations on swelling and fission gas release is negligible, but that the effect of solid fission products is important.
