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.

Implementing the NEPA Amendments Enacted by the Fiscal Responsibility Act: Improving Efficiency While Balancing Public Involvement Opportunities in Environmental Reviews The Fiscal Responsibility Act of 2023 (FRA) amended the National Environmental Policy Act (NEPA). Prior to the FRA, NEPA had been largely untouched since it was signed into law in 1970. NEPA requires Federal agencies to prepare environmental impact statements (EISs) for major Federal actions significantly affecting the quality of the human environment and provides opportunities for public participation to help inform agency decision making. This panel will review the changes made to NEPA by the FRA, and how federal agencies are updating their policies, regulations, and associated guidance. The panel will include representatives from federal agencies and environmental contractors to discuss ongoing streamlining and modernization of environmental reviews in response to the NEPA amendments, section 506 of the ADVANCE Act, and CEQ regulation revisions.
