ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

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.
