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.

To increase the electron temperature of the plasma in the central cell, electron cyclotron resonance heating (c-ECH) is applied. It is observed that both the density and temperature of the plasma decrease during the time of c-ECH, especially in the phase of wall conditioning. To understand the obtained results, plasma parameters including the H measurements at the central and anchor cells are studied. Simulation on magnetohydrodynamical (MHD) stability of GAMMA 10 is also done. It is suggested that sufficient value of the plasma in the anchor cell during c-ECH is necessary for MHD stability of the GAMMA 10 plasma. Related problem to increase the value of the plasma in the anchor cell is pointed out.
