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.

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.
Advances in Nuclear Fuel Management (ANFM 2025)
Dr. G. Ivan Maldonado is a Professor of Nuclear Engineering at the University of Tennessee (UT) Department of Nuclear Engineering and Fellow of the American Nuclear Society (ANS). He has been affiliated with the US nuclear industry for more than 30 years, with expertise in computational modeling and simulation of current and next-generation nuclear reactors and specialization in nuclear fuel management optimization. He has led a multitude of research and instructional projects with students at three universities (Iowa State, Univ. of Cincinnati, and UT) and with colleagues nationally and internationally, while mentoring 23 PhD and 50 MS graduates in the process, so far. Past projects have involved core neutronics for PWRs, BWRs, SMRs, CANDUs, VVERs, FHR (salt-cooled), MSRs, and most recently fusion reactors. Dr. Maldonado has published around 250 peer-reviewed publications with his students, has been a consultant to the US NRC ACRS, Guest Editor to the Progress in Nuclear Energy and Annals of Nuclear Energy journals, served as Technical Program Chair and Division Chair for the ANS Reactor Physics Division (RPD), and was a former Technical Program Manager with GE Nuclear Energy / Global Nuclear Fuels in support of core/bundle design, licensing, and operational management of BWR reactors in the US and abroad.
