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.

Integrated Security Solutions
Associate Labs Director
Sandia National Laboratories
As Associate Labs Director for Integrated Security Solutions, Andrew McIlroy provides leadership and management direction for Sandia’s California Laboratory and the Energy and Earth Systems Center, which includes staff in New Mexico, Texas, and Alaska. In addition, he has primary responsibility for Sandia’s Energy and Homeland Security mission portfolio, as well as for California weapon systems and component engineering. Previously, Andy was Director of the Energy and Homeland Security Program Management Center and Deputy Associate Labs Director for Integrated Security Solutions. In this role, Andy led business operations for Integrated Security Solutions and managed Sandia’s Energy and Homeland Security Program portfolio. Andy’s Sandia career began in 1991 as a Combustion Research Facility postdoctoral researcher. He joined The Aerospace Corporation in 1993 and returned to Sandia in 1997 as a technical staff member in the Combustion Chemistry and Diagnostics Department. Andy served as Manager for both the Combustion Chemistry and Diagnostics and the Reacting Flows Research departments, Senior Manager for Chemical Sciences, and Acting Director of the Materials Science Center. As Senior Manager for Livermore Valley Open Campus (LVOC) Development, Andy developed the physical and operational infrastructure for LVOC, a joint initiative of Sandia and Lawrence Livermore National Laboratory to create an accessible, common campus to foster domestic and international partnerships with industry and academia. Andy also created programs to take advantage of the LVOC. Andy became Senior Manager for Science-Enabled Engineering and led Verification and Validation for Sandia’s Advanced Simulation and Computing Program. As Deputy Chief Technology Officer for Sandia and Director of Research Strategy and Partnership, Andy led Sandia’s Laboratory Directed Research and Development Program, academic and industrial partnerships, and tech transfer programs. Andy has a bachelor’s degree in chemistry with honors and distinction from Harvey Mudd College and a PhD in chemical physics from the University of Colorado. He cochaired the Department of Energy’s (DOE’s) Basic Research Needs Workshop for Clean and Efficient Combustion of 21st-Century Transportation Fuels, coordinated the DOE Workshop on Predictive Simulation for Internal Combustion Engines, and has authored 40 peer-reviewed journal articles.
