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.

Solutions for the RF heating problems in HANBIT mirror machine have been obtained by analytically under the assumptions of uniform plasma and magnetic field [1]. For the case of non-uniform plasma and magnetic field, a numerical calculation for entire region requires considerable computing times and delicate considerations of the antenna current. In this work, we developed a hybrid method in solving the RF heating problem in which the outer region of the plasma limiter including the antenna is treated by an analytic technique and the plasma region is solved by a numerical method. Solutions for two regions are matched on the plasma-vacuum interface self-consistently without loss of generality. Using this method, we can reduce the calculation time and required computer memories and present some results for HANBIT case.
