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.

The main three subsystems of the ITER Tritium Fuel Processing Plant, the Tokamak Exhaust Processing (TEP) System, the Isotope Separation System (ISS) and the Storage and Delivery System (SDS), are equipped with enough instrumentation to control the various processes. In addition to this system-dedicated instrumentation, a central facility called Analytical System (ANS) has been designed for i) verification and determination of the composition of the various gas mixtures processed in the Tritium Fuel Processing Plant and ii) checking and monitoring the local equipment. The analytical requirements of the subsystems of the ITER tritium plant are summarised. A comparison of various analytical techniques revealed that gas chromatography is the most suitable method. The design of the Analytical System comprising three micro and two conventional gas chromatographs and its safe operation are discussed in detail.
