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.

Water distillation packed with materials having adsorption ability is proposed for wastewater detritiation, and behavior of HTO depletion or enrichment is experimentally investigated. It is proved that the apparent volatility ratio of H2O-to-HTO is increased by an isotopic effect on adsorption under a steady-state operation. Danckwerts’ surface renewal model is applied to explain the T enrichment process in a lab-scale water distillation column. The effect is estimated in terms of an adsorption enhancement factor included in the T separation factor, εHT,ad, which depends on the kinds of adsorbents and liquid-vapor flow conditions. The value of the enhancement factor is also confirmed εHT,ad = 1.02 in a comparatively large-scale distillation operation packed with Sulzer packing or Raschig ring coated with zeolite adsorbent. A large-scale distillation tower can be designed to detritiate radioactive wastewater generated in Fukushima’s Daiichi NPS based on the present experimental results.
