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.

Visco-plastic flow properties of hydrogenic solids are important considerations for the design and operation of continuous hydrogenic pellet extrusion systems. Prior to 2010, the visco-plastic flow behavior of deuterium, tritium, and mixtures of the isotopes was only known at 14 K and no heat transfer studies were available. To address these needs, a Cryogenic Couette Viscometer (CCV) was developed at the University of Wisconsin-Madison. Visco-plastic flow characteristics of solid neon, deuterium, and hydrogen were measured using the CCV from the onset of solidification to sub-cooled solid states over a range of shear rates. This paper discusses the transformation of these measurements, using the Quantum Law of Corresponding States, to predict the visco-plastic flow behavior of solid tritium and deuterium-tritium mixtures. Comparisons of predicted values with experimental measurements are made, where available.
