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.

Power quality is analyzed for the poloidal field (PF) power supply system of the Experimental Advanced Superconducting Tokamak (EAST) device. It is found that the power quality is quite different when the four-quarter PF power system is working in different operation modes. The (6k±1)’th (k is the odd number) harmonics are dominant during the electricity-cost phase while the (6k±1)’th (k is the even number) harmonics exist abundantly during the electricity-generation stage. In addition, fast Fourier transform as the data analysis method is applied to process harmonics and interharmonics. The experimental results present the characteristics of waveform and of current and power, and they show the emission features of harmonics and interharmonics, which leads to the conclusion that the energy of interharmonics and spectrum leakage caused by the harmonic clustering algorithm is recovered to an integer or that the picket fence effect results in the spectrum leakage of interharmonics.
