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.

A plasma consisting of large orbit non-adiabatic ions and adiabatic electrons is considered. For such a plasma it is possible that the anomalous transport characteristic of Tokamaks can be avoided. Experimental evidence in support of this possibility has been obtained with energetic beams injected into Tokamaks for heating in DIII-D and TFTR and with energetic fusion products in JET. Energetic particles were observed to slow down and diffuse classically in the presence of anomalous transport of thermal particles. Assuming that classical transport theory is applicable we have elected to investigate magnetic confinement for field reversed configurations (FRC's). This configuration was chosen because there are some 20 years of experimental investigation, about 600 published papers and current programs in Japan to provide background information for a case where a substantial fraction of the ions are non-adiabatic and contribute to the current. The investigation begins with self-consistent equilibrium solutions of the Vlasov-Maxwell equations. The classical Fokker-Planck equation is employed to evaluate Coulomb collisions and transport. Reactor configurations based on D - T, D - He3 and H - B11 reactions are considered. Energy balance is investigated considering the only losses to be Bremsstrahlung.
