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.
Meeting Spotlight
International Conference on Mathematics and Computational Methods Applied to Nuclear Science and Engineering (M&C 2025)
April 27–30, 2025
Denver, CO|The Westin Denver Downtown
Standards Program
The Standards Committee is responsible for the development and maintenance of voluntary consensus standards that address the design, analysis, and operation of components, systems, and facilities related to the application of nuclear science and technology.

On Friday, March 11, 2011, one of the largest earthquakes in the recorded history of the world occurred on the east coast of northern Japan. This earthquake also generated a major tsunami, causing nearly 20,000 deaths. Electricity, gas and water supplies, telecommunications, and railway service were all severely disrupted and in many cases completely shut down. These disruptions severely affected the Fukushima Daiichi nuclear power plant, causing a loss of all on-site and off-site power and a release of radioactive materials from the reactors.
The leadership of the American Nuclear Society commissioned the American Nuclear Society Special Committee on Fukushima to provide a clear and concise explanation of what happened during the Fukushima Daiichi accident, and offer recommendations based on lessons learned from their study of the event. The American Nuclear Society, a professional organization of 11,600 nuclear science and technology professionals, has a strong tradition of advancing nuclear safety, and the Special Committee on Fukushima was organized to further its members' interests in this important professional obligation.
The release of this report is the culmination of a nearly year-long effort by Special Committee members to analyze a range of factors related to what happened at the Fukushima Daiichi facility. The report was officially released at a press conference held on March 8, 2012 at the National Press Club in Washington, DC. ANS Executive Director Robert Fine made opening remarks and introductions. Drs. Dale Klein and Mike Corradini, the Special Committee co-chairs, lead the discussion of the report and the Q&A session. Special Committee members Paul Dickman — who also served as study director — and Jacopo Buongiorno, lead for regulatory issues, also appeared on the discussion panel.
ANS Special Committee Co-Chairs Dale Klein, Ph.D., former chairman of the Nuclear Regulatory Commission, Michael Corradini, Ph.D., Wisconsin Distinguished Professor of nuclear engineering and engineering physics at the University of Wisconsin, and Eric Loewen, Ph.D., President of the American Nuclear Society, discuss the goals of the ANS Special Committee on Fukushima in interviews at the 2011 ANS Annual Meeting:
