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 ratio of the damage rates in graphite irradiated in the converter and VT-4 of CP-3′ are explained in terms of the different flux spectra which existed in the respective irradiation facilities. This interpretation requires that the statistical quantity of damage resulting from a scattering event involving a neutron of given energy be nearly constant above 105 ev, and this in turn implies that the statistical amount of damage produced by a carbon atom of given energy is nearly constant above 104 ev and is in agreement with Seitz's theory. Good agreement is found between the rate at which disturbances in the lattice are accumulated and the rate of carbon atom displacement calculated from Seitz's theory, but this is not considered especially significant since the parameters had originally been adjusted to fit experimental data.
