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.

Lecture | Fourth ITER International Summer School (IISS2010) | doi.org/10.13182/FST11-A11690
Articles are hosted by Taylor and Francis Online.
This lecture was given at the 4th ITER International Summer School in Austin, Texas, May 31-June 4, 2010. It reviews the recent experimental and modeling progress made to design real-time kinetic and magnetic profile control of advanced scenarios for steady-state tokamak operation. The lecture addresses four challenging issues that need to be resolved and that are open to future research activities: (a) how to operate a tokamak in a continuous manner, (b) how to control the core kinetic and magnetic profiles of tokamak plasmas, (c) how to control the fusion burn in plasmas with dominant self-generated bootstrap non-inductive current and fusion-born alpha heating, and (d) how to control simultaneously core and edge plasma parameters.
