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.

Cheryl O’Brien
Cheryl worked for 34 years first at Puget Sound Naval Shipyard as a Naval Architect and then at the Idaho National Laboratory in engineering and management for Westinghouse, Lockheed-Martin, Bechtel, and Battelle subsidiaries as a Registered Professional Engineer. As one of few women in senior management she directed Engineering Programs including criticality and nuclear safety, engineering design, and structural analysis. Her management career included bringing green building design and clean energy advocacy to the Laboratory as one of the first LEEDTM Accredited Professionals in Idaho. With a bachelor’s and a master’s degree in civil engineering, she focused her technical expertise is natural hazard structural analysis. She was invited to speak on natural disaster testing in Tokyo and Gold Coast, and planned international conferences and led technical sessions in Manchester, Prague, Helsinki, and Mumbai. Post career, she completed a Doctor of Arts degree in Political Science with a focus on state legislative adoption of nuclear energy policy and understanding attitudes and risk perception. She then worked as Associate Director for a non-profit organization advancing women in business before founding Vision for Inclusive Engineering Workforce, Inc. in 2023.
Cheryl’s board experience includes serving as an officer of the Yellowstone Business Partnership, and on Energy Systems Technology & Education Technology Center and University of Idaho Civil Engineering advisory boards. She is currently serving as a governor appointed trustee of the Idaho State Historical Society and member of the Lewis and Clark Trail Committee.
