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.

In order to study the areal distribution of 3H in the atmosphere around the spent nuclear fuel reprocessing plant in Rokkasho,Japan, we developed a passive type sampler of atmospheric water vapor and tested its usability in the field. A polyethylene bottle with a porous polyethylene membrane at the opening was used as the sampler. The bottle contained 300 g of molecular sieve 3A (MS-3A) for adsorbing water vapor passing through the membrane. The concentration of 3H in water recovered from the MS-3A in the bottle was compared with that obtained by an active type sampler. Both 3H concentrations agreed well with each other, which showed that the method developed was practical and effective. Using the passive type samplers at nine sampling points around the nuclear fuel reprocessing plant in November and December 2007, we successfully obtained the monthly areal distributions of 3H concentrations in the atmospheric water vapor.
