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.

Radiation-induced isotopic equilibration in hydrogen gas containing tritium has to be accounted for when cryogenic distillation of hydrogen isotopes is used for their separation. In the absence of sufficient experimental data on the reaction kinetics an appropriate theoretical model is proposed. Unknown parameters of the model have been estimated with use of Möller-Plesset ab initio method. The results of calculations are in a reasonable agreement with certain experiments performed earlier by other authors. The dependencies of equilibration rate on temperature, pressure, and tritium molar fraction are established for isotope mixtures containing no impurities.
