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.

Remembering Charles E. Till
Charles E. Till
Charles E. Till, an ANS member since 1963 and Fellow since 1987, passed away on March 22 at the age of 89. He earned bachelor’s and master’s degrees from the University of Saskatchewan and a Ph.D. in nuclear engineering from Imperial College, University of London. Till initially worked for the Civilian Atomic Power Department of the Canadian General Electric Company, where he was the physicist in charge of the startup of the first prototype CANDU reactor in Canada.
Till joined Argonne National Laboratory in 1963 in the Applied Physics Division, where he worked as an experimentalist in the Fast Critical Experiments program. He then moved to additional positions of increasing responsibility, becoming division director in 1973. Under his leadership, the Applied Physics Division established itself as one of the elite reactor physics organizations in the world. Both the experimental (critical experiments and nuclear data measurements) and nuclear analysis methods work were internationally recognized. Till led Argonne’s participation in the International Nuclear Fuel Cycle Evaluation (INFCE), and he was the lead U.S. delegate to INFCE Working Group 5, Fast Breeders.
C. Rogers McCullough was the 2nd president of the American Nuclear Society, where he was also made a Fellow. He was a founding member of ANS’ Standards Committee.
Dr. McCullough was born on January 13, 1900. In 1946, he became director of the Power Pile Division of Clinton Laboratories of the Manhattan Engineer District (now Oak Ridge National Laboratories). The task of this division was to develop and build an experimental reactor using the reactor concept known as the Daniels Pile. This effort was terminated in 1947.
Subsequently, Dr. McCullough worked in chemistry and nuclear engineering at Monsanto Chemical Company. During his time at Monsanto, he served on several committees of the Atomic Energy Commission. He served first as chair of the Industrial Committee on Reactor Locations Problems (in 1951). In 1953, that committee merged with another AEC committee and became the Advisory Committee on Reactor Safeguards, which he also chaired. He served as chair of the ACRS until 1960, and continued on as a member until 1961. In 1956, Monsanto placed him on a leave of absence to work full time for AEC as deputy director for hazards evaluation. He held that position concurrently with the ACRS position until mid-1957.
He later became a consultant in chemical and nuclear engineering and served as Technical Director of Southern Nuclear Engineering, Inc., a company offering professional engineering services to nuclear and affiliated industries. Among his consulting assignments, in 1966 he consulted for Consolidated Edison on the Indian Point 2 Nuclear Power Plant, and later, on Indian Point 3.
He was a member of a number of professional organizations, including the American Chemical Society and the American Institute of Chemical Engineers, and was also Vice Chairman of the Reactor Safety Committee of the Atomic Industrial Forum, a member of the technical committee N-45 of the United States of America Standards Institute (now the American National Standards Institute, or ANSI), a member of the Subcommittee on Nuclear Power of the Boiler and Pressure Vessel Committee of the American Society of Mechanical Engineers, and Chairman of a Task Group of this same committee to write Criteria for Prestressed Concrete Reactor Vessels.
He received a bachelor’s degree from Swarthmore College in 1921, and master’s and doctorate degrees in chemistry from MIT in 1922 and 1928, respectively.
C. Rogers McCullough passed away in February of 1967.
