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.

An on-line radioiodine monitoring system designed to operate under nuclear accident conditions is tested at the hot cell laboratory of a radiopharmaceutical production facility. The purpose of the work is to demonstrate that the patented Pennsylvania State University radioiodine monitor, using stabilized NaI(Tl + 241Am) detectors, can generate information about concentration of airborne radioiodine in real time. In the test of continuous iodine monitoring, the real-time 132I activities agree with those obtained by a high-purity germanium detector within a factor of ∼4. From the simultaneous operation of two monitors, one at the inlet and one at the outlet of the hot cell filter bank, the hot cell filter bank efficiency for the removal of airborne radioiodine is estimated to be at least 99.88%.
