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.

At the Tritium Laboratory of the Forschungszentrum Karlsruhe (TLK) an experimental facility is running which is designed for the intercomparison of several hydrophobic catalysts for use in an liquid phase catalytic exchange (LPCE) column. The catalysts under comparison are from Russia, Belgium and Romania. The intercomparison is being performed by computing the height equivalent of theoretical plates (HETP) and the mass transfer coefficients for HD transfer from gas to water using the measured values of the composition. The range of HD concentration in hydrogen as carrier gas was 1000 ppm up to 2%. The gas and liquid composition at the bottom and at the top of the column and the condensed vapour composition at the top of the column are measured by mass spectrometry and IR spectrometry.
