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.

Fourier transform infrared spectroscopy and laser Raman spectroscopy were applied to reveal the reaction processes and products in the T2O-CO2 system balanced by nitrogen gas. The IR intensities and Raman activities of the products that might be created by beta induced reactions were calculated using Gaussian98 and the peaks of Raman and FT-IR were determined. It was found that the T2O and CO2 are so stable that the reaction products were not found in this study. Mass spectroscopy was also applied at the end of the experiment and it became clear that most of the condensed matter is tritiated water and the other substances by beta-decay reaction were not confirmed clearly.
