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.

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.
ICRS 14/RPSD 2022 speaker
Dr. Cool is the Vice-Chair of the Main Commission of the International Commission on Radiological Protection. He was the Technical Executive for Radiation Safety with the Electric Power Research Institute (EPRI) until December 2021, and prior to EPRI spent nearly 33 years with U.S. Nuclear Regulatory Commission, where he served in various Senior Executive and Senior Advisor positions. Dr. Cool received his Master’s and Doctorate degrees in Radiation Biology from the University of Rochester, School of Medicine and Dentistry. He is a Council Member of the U.S. National Council on Radiation Protection and Measurements and the Co-Chair of NCRP Council Committee 1 which produced NCRP Report 180, Management of Exposure to Ionizing Radiation: Radiation Protection Guidance for the United States. He has served on numerous panels and expert groups of the International Atomic Energy Agency and Nuclear Energy Agency. He is a member of the ANS, and a Fellow of the Health Physics Society.
