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.

Transmutation of elements in Pd hydrides with gas loading instead of liquid electrochemistry has been observed. The number of elements found increased for deuterated Pd samples processed with an XeCl excimer laser. The processing times were less than and more than 60 days, and some samples became incandescent when they were put into contact with air. The Pd-processed samples were analyzed with a scanning electron microscope and an electron probe microanalyzer; many pits on the surfaces of the samples were found along with the transmutation of many elements - Al, Au, C, Ca, Fe, Mg, Na, Nd, Ni, O, S, and Si - while the quartz windows, utilized to seal the cell, presented Al, C, Ca, Cl, K, Mg, Na, Ni, S, V, and Zn. Elements were also found, when the cross sections of the Pd samples were analyzed (particularly at a few micrometres from the external surface), that corresponded to the pits. Analysis of the samples that were processed less than 60 days showed that the highest X-ray peak was due to an Al-K emission line, and its intensity was 40% with respect to the Pd-L peak. In samples processed at 60 days, the Al concentration decreased while the Si-K, Fe-K, and O-K emission lines increased, resulting in the highest emission line, and their intensities were 50, 40, and 30%, respectively, with respect to the Pd-L peak.
