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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

Molecular dynamics simulations of energetic bombardment of amorphous hydrocarbon (a-C:H) materials by Ar ions up to 200 eV in energy have been performed. In addition to erosion of carbon and hydrogen atoms, the Ar bombardment causes damage and subsequent structural changes in the sample. We present a model based on potential energy analysis to characterize the damage and structural changes. The model identifies both the newly created damage due to bombardment and the local restructuring and subsequent annihilation of already existing damage. The analysis shows that although a large number of carbon atoms are displaced during the collision cascade, most of them do not contribute to the local structural change. Most of the damage creation and restructuring of the local neighborhood happens within the ion range, and, at high energy (200 eV), the restructuring continues beyond the ion range.
