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 characterization of lifetime-component capabilities of various chamber armors is a critical path to the development of the High Average Power Laser (HAPL) reactor design. Previous studies have examined tungsten as an armor material to protect the low-activation ferritic steel first wall from x-ray and ion damage.Carbon-bearing materials are of interest as candidate armor materials due to their desirable thermal and mechanical properties. This analysis examines and compares several carbon-bearing materials: silicon carbide, graphite, engineered graphitic materials and carbon nanotube composites.The transient thermal response of these materials was simulated with the BUCKY 1-D radiation hydrodynamics code utilizing the standardized HAPL x-ray and ion threat spectra. Evacuated and buffer gas filled bare-walled configurations were simulated.
