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.

Fueling the Future – Building on our Legacy
Nashville, TN|DoubleTree, Downtown Nashville
TopFuel 2025 is the leading international conference on new developments in nuclear reactor fuel performance. Held annually and rotating between Asia, Europe, and the US, this event gathers experts from around the world. The theme for the 2025 meeting is “Fueling the Future – Building on our Legacy.” It reflects our commitment to advancing nuclear fuel technology while honoring the achievements that have brought us to this point. This year, the conference will continue to emphasize Light Water Reactor (LWR) fuel performance while also expanding to include Advanced Reactor fuels. Attendees will have the opportunity to explore the latest innovations, share research, and collaborate on the future of nuclear energy.
Authors of accepted abstracts will be invited to submit full papers that are 3-10 pages in length. Full papers must describe work that is new, significant, and relevant to the conference.Authors of accepted papers must agree to register and attend the conference and present their papers. Papers that are not presented in person at the conference will not appear in the final conference publication.
