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 Inertial Confinement Fusion (ICF) Program and the Lawrence Livermore National Laboratory has made substantial progress in understanding the details of the radiation drive and the dynamics of capsules imploded by the Nova laser. A detailed understanding, validated by Nova experiments of the crucial physics for implosions is necessary before a new facility is started. A National Academy of Science Review Committee on ICF1 has recently endorsed a 12 point technical contract for the Nova program. Recent experiments have achieved a substantial number of these goals. A decrease in the level of plasma instabilities has been demonstrated by the use of phase plates. Neutron measurements have been used to demonstrate high densities in well understood implosions. A detailed understanding of the Rayleigh-Taylor instability at the ablation front of x-ray driven planar foil targets with large hydrodynamic growth factors has been proven. X-ray spectroscopy has been used to demonstrate a high fuel density and an improvement in the compression ratio of targets when a shaped pulse is used to keep a pusher on a low rho-r trajectory.
