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.

A TFTR Lower Hybrid Current Drive Project has been undertaken to scope out the design and the details of construction of a Lower Hybrid (LH) system to provide up to 4 megawatts of 4.6 GHz rf source power through a four-array coupler to TFTR. The main purpose of the this would be to provide TFTR with a current profile control system. The first phase of the project would consist of relocating the existing rf sources and associated equipment of the 2MW system from the PBX-M device as well as designing, fabricating and installing a vacuum vessel interface on TFTR and a new power splitter, coupler and waveguide would have to be implemented to interface with TFTR. Several novel features have been added to the system to adapt it to the requirements of the TFTR experiment. The second phase of the project would consist of installing additional 2 MW power sources from MIT and power supplies from LLNL.
