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.

Hydrogen isotope release properties of boron coated carbon tiles from JT-60U were investigated through secondary ion mass spectroscopy (SIMS). X-ray photoelectron spectroscopy (XPS) analysis of boron layer made by He+B10D14 method with 43 nm in thickness showed that the B/(B+C) ratio was about 0.9. Hydrogen isotopes in the boron layer and in the carbon layer were released at above 573 K and 1023 K, respectively. This means that hydrogen isotopes in the boron layer on the carbon tiles in JT-60U are released at temperatures as low as 573 K. The He+B10D14 boronization method is clearly effective to attain the high purity deuterium plasma and the low recycling because this method does not introduce H during boronization process. Wall conditioning before boronization is important because hydrogen retained in the carbon is released during plasma discharge through boron coating.
