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 supercritical helium (SHE) circulation pump, a jet pump, and a cold compressor were designed and manufactured as the first step of cryogenic component development for a large-scale cryogenic system which is required for the Fusion Experimental Reactor (FER). The SHE circulation pump achieved 320-g/s flow rate with an 0.08-MPa pressure head at 4.6 K, making it the biggest cold pump in the world. The jet pump's mass flow ratio was about 1.0 with an 0.07-MPa pressure head at about 10 K. The cold compressor was successfully operated with an inlet vapor pressure of 0.053 MPa (3.7 K) , and outlet pressure of 0.12 MPa, and a mass flow rate of 60 g/s. The designs and test results are described in this paper.
