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.

Following his groundbreaking “Atoms for Peace” speech before the United Nations on December 8, 1953, President Eisenhower in 1955 proposed the design and construction of a nuclear-powered merchant ship. With congressional approval in 1956, the 22,000 ton passenger and cargo ship NS Savannah was constructed, tested, and delivered for sea service in 1962. The purpose of the Savannah was to demonstrate the application of nuclear technology (80 MWth PWR) to merchant ships with all its new concomitant regulations, standards, training, operations, and design features. Between 1962 and 1970, when it was shutdown, Savannah had sailed over 450,000 miles, called 32 domestic and 45 foreign ports in 26 nations, carried 848 passengers, and hosted over 1.4 million visitors, all while burning only 163 pounds of enriched uranium.
An in-depth detailed virtual tour of the Savannah, now berthed in Baltimore, was developed under sponsorship by the ANS DC Section, N.S. Savannah Association, and the Maritime Administration (MARAD). This approximately 1-hour video tour takes viewers on a journey, which could not be taken in person, around and inside the Savannah which is undergoing decommissioning and decontamination (D&D). Extensive video footage accompanied by knowledgeable expert commentary was taken of the nuclear steam supply system (NSSS) inside the containment, control room, engine room, bridge, cargo holds, and public areas. The video of the interior of the containment is especially historic as component removal began right after film shooting in October 2021. Unique D&D design modifications are also featured in this virtual tour. The MARAD Savannah Project Director and the last Savannah Reactor Operator discuss design and operating features as well as memories.
A special thank you to the tour sponsors
