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 ability to interpret measured (n, 2n) cross sections by the statistical model of nuclear reactions has been tested. Good agreement was observed for 22 nuclei having mass numbers greater than 30. The statistical model was then applied to nuclei in this mass range to estimate both monoenergetic and fission-spectrum-averaged cross sections. The (n, 2n) reaction in structural materials contributes on the order of +0.1% to the reactor multiplication.
