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.

This paper investigates whether a fusion power plant could be designed to be passively proliferation-proof. Even low neutron production rates enable fissile-fuel breeding, so such a fusion reactor must burn neutron-lean fuels. To burn these fuels economically requires a high-power-density fusion concept, and a D-3He field-reversed configuration will be analyzed here. The paper discusses physics and engineering design features that would defeat attempts to modify the reactor to burn the neutron-rich fuels D-T and D-D. These include burning an advanced fusion fuel, utilizing direct energy conversion, minimizing the radius to leave inadequate room for D-T neutron shielding of superconducting magnets, designing a single-module, full-lifetime fusion core requiring no module changeout, and using an organic coolant.
