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 dedicated experimental facility has been constructed to simulate, in controlled conditions, the contamination by multielement aerosols of various agro-ecosystems typical of Europe. Large monoliths of undisturbed soils (12 t each) have been sampled throughout Europe; the extraction method used in order not to destroy the pedological zones is described. These monoliths are installed in the facility greenhouses under computer-driven climatic and hydric conditions, which mimic those of their origin. A critical comparison of the climatic values in the greenhouse and in the original sites is done. Contamination of the lysimeters is performed with a specific furnace capable of generating radioactive and stable aerosols. The general characteristic aerosols are determined. They are representative of those that would be released in the case of a severe accident in a pressurized water reactor with core fusion (2950°C).
