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 Nonproliferation Policy
The mission of the Nuclear Nonproliferation Policy Division (NNPD) is to promote the peaceful use of nuclear technology while simultaneously preventing the diversion and misuse of nuclear material and technology through appropriate safeguards and security, and promotion of nuclear nonproliferation policies. To achieve this mission, the objectives of the NNPD are to: Promote policy that discourages the proliferation of nuclear technology and material to inappropriate entities. Provide information to ANS members, the technical community at large, opinion leaders, and decision makers to improve their understanding of nuclear nonproliferation issues. Become a recognized technical resource on nuclear nonproliferation, safeguards, and security issues. Serve as the integration and coordination body for nuclear nonproliferation activities for the ANS. Work cooperatively with other ANS divisions to achieve these objective nonproliferation policies.

Colin Judge: Testing structural materials in Idaho’s newest hot cell facility
Idaho National Laboratory’s newest facility—the Sample Preparation Laboratory (SPL)—sits across the road from the Hot Fuel Examination Facility (HFEF), which started operating in 1975. SPL will host the first new hot cells at INL’s Materials and Fuels Complex (MFC) in 50 years, giving INL researchers and partners new flexibility to test the structural properties of irradiated materials fresh from the Advanced Test Reactor (ATR) or from a partner’s facility.
Materials meant to withstand extreme conditions in fission or fusion power plants must be tested under similar conditions and pushed past their breaking points so performance and limitations can be understood and improved. Once irradiated, materials samples can be cut down to size in SPL and packaged for testing in other facilities at INL or other national laboratories, commercial labs, or universities. But they can also be subjected to extreme thermal or corrosive conditions and mechanical testing right in SPL, explains Colin Judge, who, as INL’s division director for nuclear materials performance, oversees SPL and other facilities at the MFC.
SPL won’t go “hot” until January 2026, but Judge spoke with NN staff writer Susan Gallier about its capabilities as his team was moving instruments into the new facility.
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.
