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.

Results obtained in more than 100 electrolysis experiments of D2O with palladium and titanium cathodes, characterized by continuous high-efficiency neutron monitoring, are reported. In two runs with palladium cathodes, anomalous counts were observed that could not be rejected as evident spurious signals. In one of the two runs, anomalous counts were simultaneous with deformation of the palladium cathode. The two events are reported as candidate events of neutron emission. Moreover, in 2 (of 30) experiments with pulsed current, a statistically significant difference between counts in the charging and in the relaxation phases was observed. Some tritium measurements in the electrolyte solution were carried out, with no evidence of tritium contamination over the natural content. Analyses of the gases from the cathodes revealed the presence of species with masses of five and six, which could be attributed to DDH and D3 molecules.
