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.

Thomson scattering diagnostics has been updated to allow measurements at two instants of time for either of two spatial points in plasma during a single plasma discharge. Laser produces now two 15J laser pulses with variable (0.2–100s) delay between them. It was made possible by integration into previous laser system a second independent laser oscillator. Multichannel spectral measurements of scattered radiation can be accomplished at two spatial locations simultaneously, at z1 = 4m from the input of electron beam into plasma (old location) and at z2 = 2m (new location). Three geometries of measurement are possible: a single radial point at each of plasma cross-sections at z1 and z2 or two radial points at either cross-sections at z1 or z2. Number of radial points is limited by number of available detector channels (15ch) now. We present first experimental results with 90° detection of scattered radiation with upgraded system.
