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.

In order to investigate the applicability of a thermophoresis dust removal system for fusion plasma devices, the exact estimation of the thermophoretic force acting on discrete dust particle is required. In order to make up for the lack of experimental data, the thermophoretic force acting on a fine spherical particle suspended between the two parallel plates has been measured. In all conventional analyses, it is assumed that the particle is placed and stands still at the center of the confined plates. When the particle is positioned at the center of the plates, the experimental data agrees with the conventional analysis as the asymptotic behavior. On the other hand, when the particle is deviated from the center of the plates, the experimental data shows the different behavior from the analytical formula.
