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.

“Life is a roller coaster. It’s best ridden with your hands in the air.”
Craig Piercycpiercy@ans.org
I find myself saying the expression above a lot these days—to my kids, my wife, my friends, and colleagues. Most recently, I said it to the person sitting next to me after the pilot of our plane—bound for Reagan National Airport a day after the collision of AA flight 5342 and a military Blackhawk helicopter—aborted the landing at the last minute.
I am not sure where I picked up this pronouncement, but I find it to be apropos to the topsy-turvy moment where we find ourselves in 2025. In addition to the first U.S. commercial airline crash in 15 years, we are witnessing a new presidential administration in its infancy playing by the Silicon Valley rules of “move fast, break things.” We’ve seen DeepSeek, the low-cost Chinese AI that reportedly uses 50–75 percent less energy than its NVIDIA-powered counterparts, tank Constellation’s market value by more than 20 percent in one late-January trading day.
