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.

As part of the U.S. DOE Office of Fusion Energy Nuclear Data Needs program, we have continued assessment of the nuclear data needs for the development of fusion energy. We have identified and reviewed the high priority elements whose neutron emission data are needed for a near-term fusion ignition facility and fusion power reactor designs for demonstrating the scientific and engineering feasibilities of fusion energy. We found that most of the elements identified here are lacking experimental data from 6 to 15 MeV except hydrogen, lithium, beryllium, and copper. A list of high priority dosimetry cross sections was developed that includes some 29 reactions, including 6 reactions recommended by the plasma diagnostic group of PPPL. Of these 29 reactions, 18 cross sections were chosen to be included in the ENDF/B-VI dosimetry files. The activation cross sections needed for elements to be used in the near-term ignition device and future power reactors were compiled. These cross sections were prioritized according to their activation levels and half-lives of their activation products. All these cross sections are going to be included in the END/B-VI activation files.
