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.

Savannah River Site empties more waste tanks
The Department of Energy announced that waste from two more tanks at its Savannah River Site has been removed ahead of schedule. The tanks—numbers 11 and 15—are the fourth and fifth waste containers in 12 months to meet the milestone of preliminary cease waste removal (PCWR) regulatory approval, 7 and 19 months ahead of schedule, respectively, according to the DOE.
