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.

This paper deals with the well-known problem of calculating derivatives and perturbations of the multiplication factor and reaction rates by the Monte Carlo method. The central point of the problem is the fact that the fission source spatial distribution depends on the solution of the neutron transport equation. Thus, whatever perturbation of material or geometrical parameters happens, it will lead to a perturbation of the fission source spatial distribution. Ignoring this can cause significant errors. There have been proposed several techniques to consider the aforementioned fact. This paper presents another possible solution.
