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.

Electrical conductivities of weakly ionized nuclear plasmas were computed by numerically solving an electron Boltzmann equation. A pure 3He gas and 3He-Na gaseous mixtures were analyzed. The gases are ionized by fast ions (0.19-MeV tritons and 0.59-MeV protons), which are generated from in situ neutron-3He nuclear reactions. The results show that the electrical conductivity of the 3He-Na gaseous mixtures is higher than that of the pure helium gas because of the enhanced ionization of seeded sodium atoms by subexcitation electrons. This effect is not included in a standard Maxwellian model. An analytical formula of W values for gaseous mixtures was suggested to incorporate the effect of subexcitation electrons. The formula can be applied to analyze chemically complex systems.
