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 Product Storage (PS) and Intermediate Storage (IS) systems of the Active Gas Handling System (AGHS) are hydrogen isotope storage facilities. IS will take pure hydrogen mixtures from the Cryogenic Forevacuum (CF) system and store them until the isotope separation systems, Cryogenic Distillation (CD) and Gas Chromatography (GC), are ready to separate the mixtures into pure H2, D2 and T2. The purified D2 and T2 will be sent to PS for storage, while any protium will be diluted with nitrogen and discharged to atmosphere if the T2 levels are below 4 × 10−4Ci/m3. PS will then deliver gas via the Gas Introduction (GI) system to the various users. The principal parts of PS and IS are their U-bed assemblies. Each assembly consists of four uranium beds (U-bed) which each store up to 27 moles of hydrogen. The commissioning results, the absorption and desorption characteristics of the U-beds, the sequences for safe operation of the U-beds and transfer of gases to other AGHS systems, the hardwired interlock system and the over/underpressure protection system for the secondary containments will be discussed.
