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.

The influence of the port void on the thermal-neutron scalar flux at the source plane and on the current at the exit plane of a beam port is examined experimentally and analytically. Activation experiments on 1 1/2, 3-, and 5-in. diam ports inserted into the water and graphite reflectors of a swimming-pool reactor are compared with an elementary P1 analysis. The exit current is found to be well-predicted by the theory, which depends only upon a knowledge of the scalar-flux distribution when the beam port is absent.
