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 Raman spectroscopy is a very attractive method for real time, in-situ process monitoring and control in a tritium facility. From the viewpoint of safety and inventory of the tritium, the Raman spectroscopy allows the content of tritium in different points on a process to be measured. It's a dynamic measurement with a short analytical period. Coupled with fiber optics, a Raman spectrometer allows on-line analysis of a tritiated process in a glove box with the spectrometer exterior to the glove box. This method should be applied to isotopic analysis of gas mixtures. The experimental results show that this technique is suitable for qualitative and quantitative analysis of tritiated gas mixtures.
