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.

Multiple samples of moderate-burnup pressurized water reactor (PWR) and boiling water reactor (BWR) spent fuel are oxidized in controlled atmosphere dry baths at 175, 130, and 110° C. The atmosphere consists of air humidified to a dew point of either—55 or +80°C. These tests are run for up to 18.8 kh. The weight gain data from these tests are analyzed using a mathematical model incorporating the assumption that oxidation occurs by rapid grain-boundary oxygen diffusion, followed by oxidation of the individual fuel grains. The BWR fuel appears to oxidize slightly faster than PWR fuel, and the data suggest a possible increase in oxidation rate in moist air. Reasonable agreement is observed between the oxidation rate constants obtained in these long-term tests and prior short-term thermogravimetric analysis oxidation tests.
