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 previously reported work on the spherical harmonics treatment of epithermal-neutron spectra in reactor lattices is further extended and improved. The condensed matrix representation is introduced for the space- and lethargy-dependent vector of the spherical harmonics flux moments. Detailed recurrence relations for the factors resulting from numerical integration of the lethargy transfer integrals, in both the fast and the resonance regions, are provided. For solving systems of interface and boundary condition equations in the space variable, a procedure based on the coefficient matrix partitioning is presented.
