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
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

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.
20th International Topical Meeting on Nuclear Reactor Thermal Hydraulics (NURETH-20)
Dr. Neil Todreas is the Korea Electric Power Corp. Professor of Nuclear Engineering (Emeritus) and a Professor of Mechanical Engineering (Emeritus) at the Massachusetts Institute of Technology. He has served at MIT for 53 years, including an eight-year period from 1981 – 1989 as the Nuclear Engineering Department Head. From 1975 to 2020 he was co-director of the MIT Nuclear Power Reactor Safety summer course which presents current issues of reactor safety significance to an international group of over 30 nuclear engineers each summer in a one -week course .on nuclear reactors Prior to his MIT service he spent 4 years in US Naval Reactors and a subsequent 5 years in the Reactor Development and Technology Division of the US Atomic Energy Commission working on design and operation of advanced nuclear reactors His area of technical expertise is thermal and hydraulic aspects of nuclear reactor engineering and safety analysis. .
He has an extensive record of service for government (Department of Energy – DOE, US Nuclear Regulatory Commission – USNRC, and national laboratories), utility industry review committees, and international scientific review groups. He has served as a member and chair of the Advisory Council of the Institute of Nuclear Power Operation (INPO). He was the chair of the US Nuclear Regulatory Commission (NRC) panel on Appendix K (which ushered the best estimate approach with uncertainty into the regulatory practice, instead of the so-called conservative approach used until then). In the early 2000s he served as co-chairman of DOE’s Generation IV technology road map planning committee. His professional service has involved many international assignments, including technical leadership of the panel to assess the safety and restart plan for the Canadian Ontario Hydro Company’s nuclear fleet.
He has written or been co-author of more than 250 publications, a two-volume textbook published in 1990, of which Vol I ,3rd and Vol II 2nd ed are widely used internationally for the study of reactor thermal analysis He has also published a reference book on safety features of light water reactors.
He is a member of the US National Academy of Engineering and a fellow of the American Nuclear Society (ANS) and the American Society of Mechanical Engineers (ASME).
