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.
Educator Training
September 19, 2024|6:00–7:00PM (7:00–8:00PM EDT)
Available to All Users
This webinar featured an exciting deep dive into the world of radiation detection! We explored the science behind scintillators and semiconductors, key components in detecting and measuring radiation. Through a live demonstration of gamma spectroscopy, participants gained an understanding of how these tools are used in fields ranging from medical imaging to environmental monitoring. View the above recording for an opportunity to see science in action and learn how these technologies help us explore the invisible forces around us.

Biographies
Amber Johnson
Amber Johnson is the director of the University of Maryland Training Reactor and holds a senior reactor operators license. She enjoys sharing the blue glow from her open-pool reactor with the many visitors who come for a tour each year. To share best practices across the United States research reactor community, Johnson serves as editor of a quarterly newsletter that tracks news, events, and regulatory items. Before joining the University of Maryland, she was an accelerator operator at the U.S. Department of Energy’s Fermi National Accelerator Laboratory.
Mary Lou Dunzik-Gougar
Mary Lou Dunzik-Gougar is the associate dean of the Idaho State University (ISU) College of Science and Engineering, associate professor of nuclear engineering and a senior reactor operator at ISU’s Aerojet-General Nucleonics nuclear reactor, commonly known as the AGN-201. Presently, she coordinates the nuclear engineering curriculum at ISU and teaches core graduate and undergraduate courses. She also performs nuclear materials research and is involved in regional and discipline accreditations, ISU’s international program development, and reactor administration.
Mary Lou has published internationally and is recognized as principal investigator of productive research projects incorporating nuclear material irradiation and characterization and the associated management of radioactive material.
She has collaborated on a variety of projects and proposals in university, national laboratory, and international research environments. This includes her work as a joint appointee scientist at Idaho National Laboratory where she led the Simulation Institute for Nuclear Enterprise Modeling and Analysis fuel-cycle modeling project. She also worked at Argonne National Lab with various duties associated with pyroprocessing spent fuel and was also a high school science and math teacher in the U.S. and U.K.
Mary Lou has a B.S. in chemistry from Cedar Crest College and received an M.S. in environmental engineering along with her Ph.D. in nuclear engineering from Pennsylvania State University. Her research interests include the nuclear fuel cycle, nuclear fuels and materials development, spent fuel processing, and waste form development.
An ANS member since 1992, Mary Lou was on the ANS Board of Directors from 1996-1999. She is a member of the Accreditation Policy & Procedures Committee; Development Committee; Fuel Cycle and Waste Management Division; Education, Training and Workforce Development Division; the Special Committee on Government Relations; and is the faculty advisor for the ANS Idaho State University Student Section. She is an active member of the Idaho ANS Local Section and has served on numerous organizing committees for local and national meetings.
In 2011 and 2014, she was the recipient of ANS Presidential Citations in addition to the Landis Public Communication and Education Award in 2014.
This webinar is presented by ANS in partnership with the Department of Energy, Office of Nuclear Energy.
