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.

Two decades of fusion reactor conceptual design have led to a clearer definition of an “attractive” fusion power plant. Recent advances in commercial reactor designs have pushed in the direction of smaller, more compact systems while stressing material and configurational choices that amplify safety and environmental (S&E) advantages (e.g., inherent or passive safety and significantly reduced long-term radioactive waste). When intelligently amalgamated, compactness and favorable S&E characteristics can enable fusion power to be competitive. The history of fusion reactor conceptual design, the constituents of an attractive fusion end product, and recent progress infusion reactor studies as embodied in the TITAN reversed-field pinch and the more recent and ongoing Advanced Reactor Innovations and Evaluation Study (ARIES) advanced tokamak reactor designs, are reviewed. The future for magnetic fusion energy can be bright if the right physics, technology, and materials research and development (R&D) choices are made now. An important ingredient in this “right choice” is design simplification and subsystem combination to achieve requisite levels of reliability and ease of maintenance, while ensuring competitive energy costs and acceptable S&E features. Significant departures from the “conventional” (i.e., the current R&D direction) tokamak physics embodiment are required to achieve these goals.
