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.

Adsorption and desorption of D2O or H2O, as a simulator of HTO, on iron surface covered with thin iron oxide film were studied by thermal desorption (TD), electron stimulated desorption (ESD), photon stimulated desorption (PSD), X-ray photoemission spectroscopy (XPS), and scanning electron microscopy (SEM). When the iron was heated under constant heating rate (5K/min), adsorbed D2O was desorbed around 400K and 600K. Adsorbed D2O which could not be desorbed by heating to 773K could be desorbed by irradiation with photon or bombardment with electron.
