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.

Two techniques have been developed for the underwater dismantlement of the steel components of the Japan Power Demonstration Reactor (JPDR): the plasma arc for dismantling the reactor internals and the arc saw for cutting the reactor pressure vessel. In parameter tests, the cutting capability for these techniques was improved, and the characteristics of the byproducts were evaluated to enable proper design of the water purification and dross collection systems. Mockup tests, conducted as final systems performance checks, proved that the cutting systems developed are practical for dismantling the JPDR steel structures.
