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.

Theoretical evaluations of neutral beam injection (NBI) efficiency for the TJ-II helical-axis stellarator have been done for several expected scenarios using the FASOLT code, an adaptation of the FAFNER three-dimensional NBI Monte Carlo code to the peculiar geometry, vacuum vessel, and helical indented magnetic surfaces of TJ-II. The code is used in combination with another one-dimensional flux coordinates transport code (PLASMATOR). Results for 1-MW injected power, comparing coinjection and counterinjection, as well as 2- and 4-MW balanced injection, are discussed with emphasis on fast ion losses and wall loads. Some preliminary results, including radial electric field effects, are also presented.
