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.

Recently, oscillating high-speed slab jets, or liquid sheets, have been proposed for shielding the first walls of inertial fusion energy (IFE) reactor chambers from damaging X-rays, neutrons and ions. The near-field dynamics of obliquely oscillating turbulent liquid sheets were investigated in scaled experiments. Results are presented for sheets at Reynolds numbers up to 37000 oscillated along various directions at frequencies from 0 to 11 Hz and amplitudes up to half the nozzle thickness (0.5δ). Data on maximum trajectories of oscillating sheets and growth rates of stationary sheets are presented for distances up to 90δ downstream of the nozzle exit. A model for predicting the maximum trajectory is presented. The bulk of the experimental data are in reasonable agreement with this model. These results can be used to provide design guidelines for thick liquid protection.
