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 large high-energy lasers required for inertial fusion are at present beyond state of the art, and there are other problems (instability of the fuel target, suprathermal electrons, etc.) as well. Therefore, it is hoped that the energy requirement for inertial fusion can be reduced with the help of coldfusion, which takes place within the electrode material confining the fuel (avoiding instability problems). With the “semicold fusion cell,” laser energy is transferred into the “hot” part of the fuel, which is confined within the cathode in a cavity, and credit is taken from fast projectiles (tritium) stemming from the (t,p) branch of cold fusion in the “cold” metal lattice. The latter is the key to the model of a dynamic process for potential growth between the cold electrode and the hot confined fuel in the semicold fusion cell.
