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 coaxial double-tube hot-gas duct with an internal insulation layer is to be used for the High-Temperature Engineering Test Reactor (HTTR), a gas-cooled reactor designed by the Japan Atomic Energy Research Institute. A full-scale simulation of part of the hot-gas duct was constructed to verify its structural integrity. No hot spot was detected on the inner tube under HTTR operation conditions after 7700 h. Natural convection was negligible in the internal insulation layer. An experimental correlation of the effective thermal conductivity for the internal insulation layer was also obtained.
