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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.
2024 ANS Student Conference
Dr. Jess Gehin is the associate lab director for the Nuclear Science and Technology directorate. Gehin originally joined INL in 2018 as the chief scientist for the NS&T directorate, bringing nearly 30 years of experience in reactor core physics and technologies to the lab. He also serves as the National Technical Director of the DOE Office of Nuclear Energy’s Microreactor Program. Dr. Gehin worked at ORNL (Oak Ridge National Laboratory) from 1992 to 2018, where he held several positions, including Director of the Consortium for Advanced Simulation of Light Water Reactors (CASL). CASL is a DOE Energy Innovation Hub located at ORNL. In that role, Gehin held leadership responsibilities for reactor technology integration, nuclear energy programs, and reactor analysis. His academic experience includes previous positions as Associate Professor at the University of Tennessee and in teaching and advising students. Dr. Gehin earned a B.S. degree in nuclear engineering from Kansas State University and M.S. and Ph.D. degrees in nuclear engineering from the Massachusetts Institute of Technology.
