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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

“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.
