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
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.
Meeting Spotlight

Sam Altman steps down as Oklo board chair
Advanced nuclear company Oklo Inc. has new leadership for its board of directors as billionaire Sam Altman is stepping down from the position he has held since 2015. The move is meant to open new partnership opportunities with OpenAI, where Altman is CEO, and other artificial intelligence companies.
Dr. Manson Benedict was the 8th president of the American Nuclear Society (ANS).In 1957, Dr. Benedict was elevated to the status of a Fellow of ANS. In 1969, he received the Arthur Holly Compton Award in Education and in 1979 the Henry DeWolf Smyth Nuclear Statesman Award. He was the 1985 recipient of the ANS Seaborg Medal.
Dr. Manson Benedict was born on October 9, 1907. He was known for his pioneering role in nuclear engineering. He developed the gaseous diffusion method for separating the isotopes of uranium and supervised the engineering and process development of the K-25 plant in Oak Ridge, Tenn., where fissionable material for the atomic bomb was produced.
In 1951 he was invited to be MIT’s first professor of nuclear engineering in the Department of Chemical Engineering. The Department of Nuclear Engineering was established on July 1, 1958, with Dr. Benedict as the first department head.
From 1958 to 1968, Dr. Benedict was a member and chair of the Advisory Committee of the Atomic Energy Commission, appointed by Presidents Eisenhower and Kennedy.
He received many awards for his work on the Manhattan Project during World War II, and for his later career as a scientist, educator, and public servant, which focused on nuclear power and other peaceful uses of atomic energy. These included the William H. Walker award in 1947, the Perkin Research Medal in 1966, the Robert E. Wilson Award in 1968, the Enrico Fermi Award in 1972, and the National Medal of Science from President Gerald Ford in 1975. The Wilson Award citation said of Dr. Benedict, “He has served education, industry and government with quiet and unwavering dedication.” In recognition of his contributions, the Manson Benedict Fellowship fund was established in the MIT Nuclear Engineering Department in 1983.
Manson received a bachelor’s degree from Cornell University in chemistry in 1928, master’s and doctorate degrees from MIT in physical chemistry in 1932, and his Ph.D. in physical chemistry in 1935.
Dr. Manson Benedict passed away on September 18, 2006.
