Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

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.
