The blossoming of cooperation between the U.S. and Canada
The United States and Canadian nuclear industries used to be an example of how two independent teams of engineers facing an identical problem—making electricity from uranium—could come up with completely different answers. In the 1950s, Canada began designing a reactor with tubes, heavy water, and natural uranium, while in the U.S. it was big pots of light water and enriched uranium.
But 80 years later, there is a remarkable convergence. The North American push for a new generation of nuclear reactors, mostly small modular reactors (SMRs), is becoming binational, with U.S. and Canadian companies seeking markets and regulatory certification on both sides of the border and in many cases sourcing key components in the other country.

In the dry environments of high-temperature gas reactors, aerosols and dust particles can be highly nonspherical and even chainlike agglomerates, and are highly charged. To elucidate the role of both shape and charge on particle dynamics, we have explored numerical solutions of the Poisson equation for arbitrary geometries. In this paper, we describe the general computational framework, and report results for condensation/evaporation for several different cases, including chainlike agglomerates. We find that the shape factor based on the volume equivalent sphere approximation underestimates the actual condensation rate on the agglomerate, in addition to not accounting for the local condensation rates.
