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.

The final drift, compression, and focusing segment of a heavy ion beam (HIB) driven inertial confinement fusion (ICF) reactor delivers the accelerated bunch of ions to the target with the required pulse length and beam spot size, in essence matching the accelerator output parameters to the desired beam parameters at the target. In this paper, we summarize the final drift, compression, and focusing design for the W.J. Shafer Associates (WJSA) Reactor Design Team's OSIRIS1,2 HIB-driven ICF reactor. Our design rearranges the bundle of beams emerging from the linac into two vertical columns, transports each column to a beam compressor, rearranges the columns into large-diameter rings, then focuses each of the beams in the target. Rationale of the design features and description of the beamline elements are given.
