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 analysis is presented of the radioactive wastes from the International Thermonuclear Experimental Reactor (ITER) and how those wastes would fit into the regulatory environments of four potential host nations: France, Germany, Japan, and the United States. The reactor described in the ITER Draft Interim Design Report is used as the basis for the radioactive inventory assessments that are carried out using ONEDANT for the neutron transport calculations and ACAB for the activation calculations. The radioactive material produced by operation of the reactor is rated according to the protocols for waste management in each nation and at specific disposal sites currently operating in those nations. Results of the assessments vary drastically between disposal sites - even between near-surface-burial sites within the U.S. Department of Energy. One disposal site (Westinghouse Hanford Company) could accept all of ITER's wastes after a storage and cooling period (all wastes are assessed at 30 yr after shutdown). Other sites (the Savannah River and the Nevada Test Sites) could not accept any components within the toroidal field coils, similar to the restrictions in Germany. Blanket modules would be excluded from near-surface burial in France and Japan, but other components may qualify.
