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.

Reactor coolant circulation following the Three Mile Island Unit 2 core destruction distributed fuel within the reactor coolant system and into the connected auxiliary systems. The collection sites generally were the low points, the horizontal surfaces, and, to a lesser extent, the vertical surfaces. The affected auxiliary systems included the reactor coolant drain tank, the letdown system, the makeup and purification system, the liquid waste systems, and the reactor coolant pump seal return lines. Steam flow to the steam generators could only move small particles (<1 mm). Smoke formation during core degradation accounted for much of the film formation in the upper elevations of the coolant system. Restart of the reactor coolant pumps accounts for the larger particles found in the steam generators.
