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 error characteristics of both high-resolution gamma spectroscopy and high-level neutron coincidence (HLNC) measurements, separate or combined, are discussed as they apply to nondestructive analysis of plutonium-bearing materials. Expressions have been derived to estimate the overall variance in the 240Pu effective mass and in the total plutonium mass in terms of the specific contributions from uncertainties in the measurements, the pertinent physical variables (including isotopics and impurities), and the instrumental constants. Experimental data available in the published literature have been used to illustrate the error characteristics of the HLNC and the effects of isotopic error correlations associated with materials having different burnups.
