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.

An exact solution for a heterogeneous, discontinuous wide beam is developed herein having three unique boundary condition (BC) sets. These BC sets were chosen based on their relevance to plate-type–fueled reactors. This solution, with respective BC sets, contributes new insights into the field of engineering mechanics as applied within the nuclear engineering discipline. Herein, the exact solution is validated under a set of test cases. A comparison is then made against other relations that have been developed to provide similar engineering insights. Last, the solution is applied toward a presently relevant engineering problem regarding the design of a monolithic plate-type fuel. The outcome of this work provides a solution form for the computation of out-of-plane deflection of a heterogeneous, discontinuous wide beam that can be easily applied in engineering mechanics and is flexible in use.
