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.

Feinstein Institutes to research novel radiation countermeasure
The Feinstein Institutes for Medical Research, home of the research institutes of New York’s Northwell Health, announced it has received a five-year, $2.9 million grant from the National Institutes of Health to investigate the potential of human ghrelin, a naturally occurring hormone, as a medical countermeasure against radiation-induced gastrointestinal syndrome (GI-ARS).
Technical Session|Panel|Sponsored by NISD

Session Chair:
Curtis L. Smith
Session Organizer:
Robert W. Youngblood
This panel is one in a series of panel discussions sponsored by ANS's Risk-Informed, Performance-Based Principles and Policy Committee on incorporation of RIPB principles into ANS standards. This panel will include a report on RP3C's development of a Guidance Document aimed at standards developers to help incorporate RIPB principles into their standards, (tentatively) a presentation on the current status of a standard under development, a discussion of Southern Company's use of the "affirmative safety case" concept in their approach to non-LWR licensing basis development, and a brief presentation on ANS's newly constituted "Advanced Reactor Working Group."
