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 H (or D, or T) Sievert's constant for liquid Sn-Li alloys is calculated from thermodynamic data issuing of the Sn-Li binary phase diagram analysis. The range of temperatures investigated is 600-873 K (Sn0.8Li0.2 m.p. ~ 599 K) to maintain single-phase binary melts. The thermodynamic functions of Li-H, Sn-H, Sn-Li are evaluated to derive those of Sn-Li-H. Thus, monotectic solubility data for Sn and Li is analyzed. The calculation is done for high-dilution conditions. A quasi-chemical regular solution model is used for temperature/composition extrapolations when no data is available. The tritium Sievert's constant in Sn0.8Li0.2 at 600 K is: 9.65 10-8 Pa-12, five times the Reiter's measured value for Pb-17Li and ~ 6 times the value in Pb-17Li eutectic obtained by using the same theoretical approach.
