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.

The results of studying efficiency of water detritiation by “hydrogen - water” chemical isotope exchange in laboratory-scale facility with membrane contact devices including perfluorosulfonic cationite Nafion-type membranes and platinum hydrophobic catalyst RCTU-3SM are presented. It has been shown that a decrease of detritiation efficiency caused by poisoning membranes with metal ions coming from equipment materials due to their corrosion after long-time operating the facility can be observed. It has been shown as well that modification of a membrane by metal ions followed by its regeneration allows not only to restore but also to increase significantly the efficiency of mass-transfer in membrane contact devices. For example, replacing membranes in contact devices of the laboratory-scale facility resulted in increasing the column separation degree by a factor of more than 7 in comparison to initial value obtained at similar conditions.
