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.

In this paper, we focus on methods to control a steering angle more effectively for a Laser Fusion Rocket (LFR). We propose a new coil configuration which is virtually one ring coil formed by a lot of small square coils and these coils make a flexible magnetic nozzle to control the reflection of fusion plasma for obtaining thrust in the space. We investigate the fusion plasma behaviors in this magnetic nozzle by using 3D hybrid simulation code and evaluate the thrust efficiency and the steering angle for several coil configurations. We found that new coil configuration proposed has desirable features from technical view points.
