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.

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.

John J. McKetta Centennial Energy Chair Professor, Mechanical Engineering,The University of Texas at Austin
Dr. Michael E. Webber is the John J. McKetta Centennial Energy Chair in the department of mechanical engineering at the University of Texas at Austin and CTO of Energy Impact Partners, a $3 billion cleantech venture fund. From September 2018 to August 2021, Webber was based in Paris, France where he served as the Chief Science and Technology Officer at ENGIE, one of the world’s largest energy companies. Webber’s expertise spans research and education at the convergence of engineering, policy, and commercialization on topics related to innovation, energy, and the environment. His book Power Trip: The Story of Energy was published in 2019 by Basic Books with an award-winning 12-part companion series spread out over two seasons that aired on PBS, Amazon Prime, AppleTV, and in-flight entertainment on American Airlines. The series had more than 10,000 broadcasts in the United States and has been distributed in dozens of countries, ultimately reaching millions of viewers. He was selected as a Fellow of ASME (the American Society of Mechanical Engineers) and as a member of the 4th class of the Presidential Leadership Scholars, which is a leadership training program organized by Presidents George W. Bush and William J. Clinton. Webber has authored four full-length general interest books, created two interactive textbooks, written more than 500 publications, and been awarded 6 patents. He serves on the advisory board for Scientific American and GTI Energy (an industry consortium formerly known as the Gas Technology Institute). A successful entrepreneur, Webber was one of three founders in 2015 for an educational technology startup, DISCO Learning Media, which was acquired in 2018. Webber holds a B.S. and B.A. from UT Austin, and M.S. and Ph.D. in mechanical engineering from Stanford University. He was honored as an American Fellow of the German Marshall Fund and an AT&T Industrial Ecology Fellow on four separate occasions by the University of Texas for exceptional teaching.
