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.

This workshop will demonstrate a new tool for use with the MCNP(TM) radiation transport code tool known as p-study. The p-study tool effectively does total Monte Carlo by perturbing all physical configuration values accessible from the input stack and allows these to be propagated into a comprehensive tally uncertainty in the end. Specifically this workshop will serve as a tutorial on a new Operational MCNP GUI (OMG) that allows users to generate and run p-study to conduct this total Monte Carlo on their input stacks. Attendees are recommended to have MCNP6.2 installed on their laptop if they want to download the GUI and follow along in the tutorial, otherwise attendees can just observe. The workshop will start with a brief statistics review sufficient to understand p-study and will assume attendees have at least some familiarity with the MCNP code.
