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.

An exact solution is developed for a plane source of thermal neutrons embedded in an infinite array of absorbing plates. Using methods based on generating functions and the theory of complex variables, we can obtain explicit values for the flux at the plate surfaces and hence at any position within the lattice.The effect on the flux distribution of allowing the plate absorption parameter (Galanin's constant) to be a random variable, uniformly distributed between an upper and lower limit, is calculated. It is found that randomness leads to a reduced rate of decay with distance from the source, in agreement with other theories concerning this problem.
