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.

While many issues affect the composition and quantity of the nuclear source term, one significant factor is the existence of aerosols. These aerosols, found in the containment structure and in the primary reactor vessel, are usually simulated with the assumption that they are spatially homogeneous. We describe here new investigations of the applications of the Direct Simulation Monte Carlo method and a mesh-free technique to spatially inhomogeneous aerosol evolution in a number of nonspherical and complex geometries. Deposition, coagulation, and condensation aerosol processes are included, and results are reported for a sphere, ellipsoid, torus, elliptical cylinder, cuboid, and a spherical geometry containing an internal obstruction. Our progress here is a precursor to construction of an MCNP-like code for simulating aerosol evolution.
