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 solvent fire in the extraction process of a fuel reprocessing plant is postulated. Because of the high concentration of fission products and large amount of nuclear fuel materials in the extraction process, it is necessary to demonstrate that these radioactive materials can be confined by the air ventilation system during a solvent fire. Large-scale tests are performed in a fire/filter facility to evaluate the effectiveness of a ventilation system including high-efficiency particulate air (HEPA) filters to confine radioactive materials. It is demonstrated that the integrity of the filters in the ventilation system can be maintained, and the decontamination factor of HEPA filters for smoke particles, which might contain radioactive materials, is sufficiently high during a postulated solvent fire.
