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.

The operation of the ITER machine requires the implementation of two sets of coil systems installed inside the vessel - the edge-localized mode (ELM) coil system and the vertical stabilization (VS) coil system. The ELM coils generate resonant magnetic perturbations in order to reduce high power deposition in the divertor induced by ELM heating and can as an option be used to control moderately unstable resistive wall modes (RWM). The VS coils provide fast vertical stabilization of the plasma. There are three ELM coils in each 40 degrees vacuum vessel (VV) sector; one each in the lower, middle and upper segments for a total of twenty seven individually powered coils. ELM coils are 6-turn rectangular coils. There are two VS coils in the VV, in the lower and upper segments below and above the lower and upper ELM coils respectively. Each upper or lower VS coil is made with 4 turns independently fed for failure recovery in the event of a faulted turn. The In-Vessel Coils (IVCs) and feeders are placed under the blanket shield modules and manifolds and need to be compatible with them. An integrated design concept has been developed that provides for an integrated design of the IVCs and their feeders, the blanket manifolds and the blankets and their respective attachment features to the VV.
