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

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.
2020 ANS Virtual Winter Meeting Plenary Session Appearance
Dr. Kris Singh is the Founder, President and CEO of Holtec International which he established in 1986 and nurtured its steady rise into a multi-national company with its business footprint in 18 countries on five continents.
Dr. Singh received his Ph.D. in Mechanical Engineering from the University of Pennsylvania, Philadelphia (1972), a M.S. in Engineering Mechanics also from Penn (1969), and a B.S. in Mechanical Engineering from BIT Sindri (Ranchi University), India (1967). Dr. Singh was elected to the National Academy of Engineering in 2013 for his seminal impact in the energy sector of mechanical engineering. He received Edison Foundation’s “Thomas Alva Edison Award” in 2015 for his ecologically and environmentally impactful inventions. Rutgers University named him “South Jerseyan of the year – 2016” for his significant beneficial impact on the South Jersey region. In 2015, he received the George Washington medal from the Engineer’s Club of Philadelphia. In 2017, the National Academy of Inventers elected him a Fellow and the University City Science Center (Philadelphia) inducted him to its “Walk of Fame.” The Pan American Academy of Engineering, the Americas institution of leading engineering thought leaders, elected Dr. Singh to its Academy in 2020. In 2019, he was elected to the Academy of Science, Engineering and Medicine of Florida, and named a guest professor in Mechanical Engineering by the University of South Florida (Tampa). He was named a Fellow of the American Society of Mechanical Engineers in 1987 for his numerous contributions to heat exchange technologies. He is an overseer at the University of California, Berkeley, and a senior fellow in Mechanical Engineering at the University of Pennsylvania. He is a registered Professional Engineer in Pennsylvania (since 1974) and Michigan (since 1982) and a member of the American Nuclear Society (1979-present).
A widely-published author in scientific journals (some 70 technical papers, one textbook and numerous symposia volumes) and a prolific inventor (121 patents granted, many pending), Dr. Singh has led Holtec International since the company’s inception, building it into a technological powerhouse respected for its engineered goods and services around the world with nine major operations centers around the world. Over 120 nuclear plants around the world employ Holtec’s systems and equipment many based on Dr. Singh’s patents. In recent years, Dr. Singh has been
leading Holtec in the global race to develop a “walk away safe” small modular reactor to make nuclear energy an economical green power alternative.
An intrepid entrepreneur and a socially conscious industrialist, Dr. Singh has built a $310 million Technology Campus on the Delaware River in Camden, NJ to create much needed employment in one of America’s poorest cities. Thanks to the steady stream of design innovations, Holtec is widely held to be pre-eminent in management of used nuclear fuel. In his early career, Dr. Singh taught numerous graduate level and continuing education courses, published 70 technical papers, authored numerous books and monographs, and contributed to the creation of several national codes and standards for equipment and system design.
He is currently an Emeritus member of the University of Pennsylvania’s Board of Trustees, where he served from 2009-2017, and a member of the University’s Board of Overseers for the School of Engineering and Applied Science (2005-present). In addition, he serves on the Board of the Nuclear Energy Institute (1998-present), Eos Energy Storage, LLC (2020-), and the Cooper Health System (2013-present). He is also a Director of the Washington, DC-based Atlantic Council, and a member of the “National Investment Council” that advises the President of Ukraine. He chairs the KPS Foundation (2001-present), a charitable Singh family foundation whose signature contribution to the advancement of science is the completion of the “Krishna P. Singh Center for Nanotechnology” at the University of Pennsylvania in Philadelphia in 2013. The KPS Foundation is also active in improving child literacy in India
