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.
2023 ANS STUDENT CONFERENCE SPEAKER
Craig serves as the CEO of the American Nuclear Society, a position he has held since November 2019. He has over 25 years of experience in nuclear policy as a congressional chief of staff, associate staff for the House Appropriations Committee, and public affairs advisor for corporations, labs and universities.
During his time on Capitol Hill, Craig led efforts to preserve federal nuclear R&D funding and to accelerate cleanup of the U.S. Department of Energy’s defense nuclear sites. As ANS Washington Representative, Craig played a central role in several high-profile policy victories, including the creation of the Nuclear Energy University Program (NEUP) and Integrated University Program (IUP) and defeating legislation that would have banned the commercial use of 14 radioisotopes.
Craig has a bachelor’s degree in Government and Politics from the University of Maryland, College Park, and is a graduate of the Public Affairs Institute. He lives in Bethesda, Maryland, with his wife Clare and is an avid skier, canoeist, and Formula One fan.
