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 novel system for energy production is presented. This system has a modular composition of homogeneous reactors with H2O and 242mAm as a fuel. These reactors are spheres of 0.11-m radius and 1-MW(thermal) power and with a critical mass of 0.0201 kg of 242mAm.The advantages of homogeneous reactors are constant fuel reprocessing and constant refueling. As a result, there is a reduction of fission products, which improves the ratio of natural cooling to heat production with respect to a loss-of-control accident (LOCA) and other safety aspects. Homogeneous reactors also have a large negative temperature coefficient and small inherent excess reactivity during operation.The reactor concept we have presented for a very small, homogeneous reactor, further enhances the safety aspects in the case of a LOCA, because of a large surface-to-volume ratio.The improved safety, the simplicity, and the small volume should compensate for the use of an unconventional nuclear fuel.
