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 Japan Atomic Energy Research Institute (JAERI) has developed a full scale Fuel Cleanup System (JFCU) that processes a simulated plasma exhaust at the Tritium Systems Test Assembly (TSTA) in the Los Alamos National Laboratory (LANL). The JFCU was designed by the Tritium Process Laboratory (TPL) of the JAERI based on the component studies performed under previous TSTA-TPL collaboration and the pilot scale experiment using grams of tritium at the TPL. The JFCU accepts a simulated fusion reactor exhaust, a mixture of hydrogen isotopes with an impurity level of up to 15% at a throughput of 4.2x10−3 mol/s continuously and produces pure hydrogen isotopes while exhausting tritium-free waste gas. Some newly developed components, such as the Ceramic Electrolysis Cell and the large Zirconium-Cobalt bed, required special attention during fabrication and assembly. The apparatus was fabricated by Mitsubishi Heavy Industries (MHI) and installed at the TSTA in early 1990. Interfacing with the existing TSTA facility also required careful interaction between TSTA and JAERI.
