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.

The continuous efforts dedicated to increase the predictive power of risk assessment for the large tritium releases imply models based on process level analysis. Tritium transfer from atmosphere to plants and the subsequent conversion into organically bound tritium strongly depend on the plant characteristics, seasons, and meteorological conditions, which have a large variability. This paper presents an inter-comparison of different models for canopy resistance and photosynthesis based on knowledge from plant physiology, agro meteorology, crop science, and atmospheric physics. The authors use Jacobs-Calvet-Ronda approach to model the canopy resistance combined with photosynthesis model and the data base taken from WOFOST crop growth model. The same photosynthesis model is used to assess the organically bound tritium production during the daytime and night time.
