High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

Applications of aerosol dynamics include modeling cloud formation and pollution in atmospheric sciences, inhalation and radiation doses in health physics, and particle transport and contamination in nuclear safety. To improve the fidelity of computed aerosol evolution to realistic process models and phenomena, efforts have been directed at the use of the Direct Simulation Monte Carlo (DSMC) technique. This paper first verifies the results obtained from the DSMC technique against a known analytical solution of a specialized case in which the evolution of a purely growing aerosol is coupled to its environment. Next, it applies the DSMC technique to the evolution of aerosol particles undergoing condensation, coagulation, and deposition as coupled to the environment.
