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.

A theoretical analysis concerning fission counter design and operation shows that an optimum ratio of cable impedance times detector capacitance over detector collection time exists for fission counters. Tests were performed to show the effects of gamma fields on fission chambers having different electrode spacings and various argon-nitrogen fill gas mixtures and pressures. Based on these tests, the FFTF in-vessel fission counters will have 0-080-in. plate spacing and be filled with 1.75 atm of Ar—7% N2. The electrode coating thickness will be 2 mg/cm2 of U3O8 (93% 235U enriched).
