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.

Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

In this paper, multi-electron interactions for low-charge-state ions in heavy ion beam fusions (HIBF) is studied through exploring theoretical approaches and developing improved models. An improved classic trajectory Monte Carlo model and corresponding codes have been built to implement those simulations, mainly though the intensive computations in solving many-body Hamiltonian Equations. Following the results present in the previous meetings (Ref. 1-2), the results here for the low-charge-state ions of Xe, Bi and other ions colliding with noble gas are provided, and show that multi-electron effects are obvious and their cross section can reach about 40% of the total cross section. The improved code employs parallel computing, and is expected to be an integral part of a plasma simulation package to study the atomic effects in plasma beam transportation and focusing in HIBF, and help to provide improved physical insight into current HIBF experiments and future studies.
