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.

Nuclear fuel cycle reimagined: Powering the next frontiers from nuclear waste
In the fall of 2023, a small Zeno Power team accomplished a major feat: they demonstrated the first strontium-90 heat source in decades—and the first-ever by a commercial company.
Zeno Power worked with Pacific Northwest National Laboratory to fabricate and validate this Z1 heat source design at the lab’s Radiochemical Processing Laboratory. The Z1 demonstration heralded renewed interest in developing radioisotope power system (RPS) technology. In early 2025, the heat source was disassembled, and the Sr-90 was returned to the U.S. Department of Energy for continued use.
Nuclear science is the study of one of the smallest things we know—the atomic nucleus. But, even though it’s 100,000 times smaller than an atom, the tiny nucleus has a huge impact on our world. Nuclear science and technology bring us cancer treatments, power for space missions, new crop varieties, safer medical supplies, and some of the cleanest and greenest ways of generating electricity.
Come with us to explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Nuclear Science 101
The study of nuclear science begins when the atom was first imagined more than 2,000 years ago. But the nucleus, the foundation of nuclear science and technology, wasn't discovered until 1909. Learn about nuclear nuclear science, its history and the processes behind technologies from the past, present and into the future.
Nuclear Energy
Nuclear binding energy holds the atoms that make up our universe together. This energy is released when atoms split apart, undergoing fission, and when smaller atoms combine together through fusion. Fission and fusion create abundant energy without releasing harmful pollutants--including carbon dioxide--into the atmosphere, making nuclear a clean, green solution for our energy future.
Navigating Nuclear: Energizing Our World
Engage students with curriculum for grades 3 through 12 backed by the expertise of leaders in nuclear science—the members of the American Nuclear Society and the Department of Energy, Office of Nuclear Energy. Resources include STEM project starters, digital lesson plans, nuclear industry career profiles, and exciting Virtual Field Trips!
K-12 Programs
Our programs serves educators and students through a suite of resources, including classroom visits by nuclear science professionals and researchers, career exploration opportunities, teacher training and out-of-school programs for students.
K-12 Resources
Along with our Navigating Nuclear curriculum and activities, ANS has many other resources that help create engaging experiences in the classroom or out of school for students of all ages. Make sure to check out our Scouts Patch, 'Get to Know Nuclear'.
