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.

Single and double sapphire spheres have been precisely suspended in 300 mg/cm3 RF aerogels without a supporting stalk by modifying parameters such as gelation time and stability of the aerogel precursor solution and use of a vacuum holder for the sphere placement. A process for fabricating a single-sphere target was also developed using a spider silk support (approximately) 100 times thinner than the earlier work on similar targets. Characterization of the ball placement and the aerogel was done by radiography. Data from the characterization of these targets showed that the ball was accurately placed and the aerogel matrix was not significantly altered.
