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 vacuum vessel wall with a postulated crack is modeled by using the two-dimensional solid finite elements. The J-integral value, a criterion of fracture mechanics, is calculated to estimate the integrity of the vacuum vessel wall with a postulated crack.
The analytical results show that the J-integral value of a crack having a quarter depth of the wall width is considerably less than the fracture toughness JIC when the membrane stress is less than the 0.2% proof stress of the unirradiated material, even if the vacuum vessel is irradiated to 3 dpa. This means that a shallow crack in the vacuum vessel wall does not become critical in the design load.
