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.

New this year, Executive Panels have been added to provide busy nuclear professionals a broader look at developments in nuclear science and technology and their impact on policy and markets. The Executive Panels will focus on crisis communications, diversity and inclusion, lessons learned from new construction projects, and the 2021 Polar Vortex energy blackouts as well as advances in space technology, non-power technologies and nuclear capabilities, and action on nuclear waste.
Be a part of one of the largest gatherings of nuclear professionals in the country where the brightest minds engage – and inspire – leaders from across the nuclear science and technology landscape.
