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
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

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.

Past CONTE conferences have included a panel discussion of industry operator licensing and training issues. Feedback on this panel has been positive and with a number of issues in this area currently, it is relevant that CONTE 2023 include a similar panel discussion. The Operator Licensing Panel for CONTE 2023 will include key members of the NRC and Industry who will participate in a discussion fueled by a question-and-answer format. Participants will have open-forum access to the panel to address issues, questions, concerns and challenges related to the topical area. Participants will be identified closer to the conference but will be personnel with extensive experience and expertise relevant to operator licensing, training and examination. Topics may include some or all of the following: • Recent revisions to NUREG-1021 • Recent revisions to Operator Knowledge and Ability Catalogs (NUREG-1122 and -1123) • Recent operator examination experience and issues • Industry items of interest The Operator Licensing Panel is a popular, open and effective forum for the discussion of, feedback on and exchange of ideas for the topical area.
