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.

A new dynamic bolting analysis has been conducted to verify the design quality of a G10 ring for the National Spherical Torus Experiment Upgrade (NSTX-U). The G10 ring under the centerstack casing and lower skirt plays a critical role in NSTX-U with large electromagnetic forces during plasma drifts, quench, and halo currents. Inspections of the installed condition of the G10 ring showed a poorly shimmed interface between the ring and the toroidal field flags. This paper will describe how to define the bolt preload to resolve this underperformance issue with the G10 ring by transient bolting analysis. The simulation results of transient bolt reaction forces show that the loads imposed on the G10 ring are within the tested capacity of the Keenserts and G10 ring.
