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.

A model is described which permits conservative homogenization of a random distribution of low-enriched UO2 pellets in a low-enriched UO2 powder and water mixture. The model is used with a Monte Carlo criticality code to demonstrate the criticality safety of General Electric Model BU-5 bulk uranium shipping containers which are used for the transportation of unirradiated uranium compounds in the form of powder or pellets, moderated to any degree and enriched to a maximum of 4 wt% in the 235U isotope.
