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.

Metal Organic Chemical Vapor Deposition (MOCVD) process is a vapor phase growth technique which is synthesized via vapor phase from metal organic complex material and will become one of the desirable deposition methods to form oxide layer on the complicated shape ducts and large-area walls of breeding blanket components. The single phase erbium oxide (Er2O3) coating layers were able to be synthesized on metal substrates such as stainless-steel 316 (SUS316) and vanadium alloy and Si single crystal plates. In this paper, the hydrogen permeation and electrical property of Er2O3 coating layer via MOCVD process will be mainly reported. The hydrogen permeation quantity of Er2O3 coating layer estimated by QMS was decreased by 1/20 compared with SUS 316 at 400 °C. In addition, the demonstration of Er2O3 coating into the interior surface of the stainless-steel was also succeeded.
