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.

Christmas Night
Twas the night before Christmas when all through the houseNo electrons were flowing through even my mouse.
All devices were plugged in by the chimney with careWith the hope that St. Nikola Tesla would share.

Tritium distribution in stainless steel type 316 exposed to hydrogen containing 32% of tritium at room and elevated temperatures was studied using thermal desorption, analysis of bremsstrahlung spectrums and acid etching techniques. All samples exhibit a large fraction of the overall tritium inventory concentrated in a thin sub-surface layer of ≈15µm thickness, where tritium concentration is by ≈2 order of magnitude larger than that in the bulk. Observed tritium depth profiles are in contradiction with a classical mechanism of hydrogen penetration to metals by atomic diffusion.
