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 purpose of the MARVEL project is to develop, in less than 2 years, a nuclear microreactor applications test bed at INL to perform research and development on various operational features of microreactors to ultimately improve integration of microreactors to end-user applications. Through collaboration between the DOE Microreactor Program and the National Reactor Innovation Center (NRIC), the development of this test bed provides an opportunity to establish and exercise key NRIC capabilities that support future reactor demonstrations by: (1) providing an early-stage platform for potential end users of microreactor systems, (2) deploying the first small-scale R&D reactor in 40 years to support new capability development, (3) facilitating outreach activity with stakeholders interested in novel nuclear energy applications (e.g., hydrogen production, process heating, water purifications), and (4) investigating and addressing issues relating to fabrication, assembly, rapid installation, deployment, and operation of microreactors. The panel will provide an overview of the MARVEL from the perspective of key contributors and stakeholders.
