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 the ion cyclotron range of frequency (ICRF) heating experiments on GAMMA 10, wave-wave and wave-particle interactions are investigated. Low-frequency fluctuations of around 100 kHz with beat frequencies among the AIC modes have been observed. These low-frequency modes are also detected in the signal of electrostatic probes in the central cell and in the signal of end-loss high-energy ion detector. Axial transport (velocity space diffusion) of high-energy ions due to beat waves among the AIC modes is clearly indicated. On the other hand, radial transport of high-energy ions due to the drift-type fluctuations has been observed in the central cell. The excitation of low-frequency magnetic fluctuations of which frequencies, fLF, are less than 1 MHz and satisfy the relation of fLF = fICRF - fAIC, where fICRF is the frequency of the heating ICRF wave and fAIC the frequency of the AIC modes. The parametric decay of the heating ICRF waves to the AIC modes and low-frequency waves will be a possible mechanism.
