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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

Gas nuclear transmutation effects in aluminum nitride were studied by the isotope tailoring method. In this method, nearly identical materials with two different radio-isotopes of nitrogen-14 (Al14N) and 15(Al15N) were prepared. The Al14N and Al15N specimens were irradiated in the JOYO fast reactor and the HFIR thermal reactor. The results were analyzed and compared to accumulated irradiation data from JMTR and JOYO. The data clearly shows the effects of gas nuclear transmutation on the linear dimension change.
