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 full scale experimental assembly for study of the hydrogen isotope separation by cryogenic distillation is described. The cryogenic column has the diameter up to 300 mm, height of 5,5 m and place in the vacuum jacket diameter of 1200 mm and height of 6,5 m. There is a possibility to change the mass exchange sections of the column with various packings replacing of sections with diameter from 80 to 300 mm. Circulation gas flow in the column is up to 10 kMol per hour. Hydraulic and separation characteristics of the mass exchange packings of various types were studied by using the next working mixtures: Ar-O2, o-p-H2, H2-HD-D2, HD-D2-DT. The best values of the height transfer unit (HTU) were obtained for the packing produced from copper wire and put through chemical treatment and plate type with a small distance between plates. HTU was equal respectively 5–6 cm and 7–8 cm. A set of experiments was carried out for the improvement and understanding of the problems connected with safety of detritiation plant, for example, the freezing of air on the cryogenic surfaces of the column when in the jacket the microcrack is formed during operation and et. al.
