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.

Inconel 600,Inconel 625 and austenitic steel (AISI 304LN) surfaces were cleaned in UHV by laser pulses of 1J total energy. Residual surface contamination layers were dissociated and desorbed. The surface cleanness degree reached was equivalent to that obtained by conventional cleaning techniques like bulk heating and sputtering by ion bombardment. A comparison between these three techniques is presented. The laser cleaning efficiency was found to be strongly dependent on the initial surface contamination degree and on the residual gas composition. In particular the effect of laser shots on the activation of the surface oxidation process at ambient pressures of about 10−9 mbar of CO was studied. The possibilities of using the laser heating technique as a tool in plasma edge diagnostic (in situ cleaning of probes,analysis of trapped particles, redeposition measurements,…) in fusion devices is discussed.
