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.
2024 International Congress on Advances in Nuclear Power Plants (ICAPP) SPeaker
Tokyo Institute of Technology (Japan)
Prof. Narabayashi graduated the master course of Nuclear Engineering, Tokyo Institute of Technology (Tokyo Tech), and entered Toshiba Corporation in 1978. He got a doctor degree in 1991 from Tokyo Tech. He was the Chief Specialist of Reactor Components and Two-Phase Flow in Toshiba Corp.
He moved to the Hokkaido University in 2005. He was given awards from the AESJ in 1988 and 2002, and from the JSME in 2005, 2022 and 2023.
He has been involved in an advisory meeting member of NISA with regard to technical lessons learned from the Fukushima Daiichi NPP accidents, and also safety counter measure evaluation member of NRA.
He became a director of the AESJ in July 2012. Since 2013, he has served as a member of the Nuclear Education Panel at King Khalifa University in the UAE, and in 2018 was awarded the Outstanding Professor of the Year Award by the Information System for Radiation Exposure (ISOE), which is jointly operated by the IAEA and OECD/NEA.
He became a specially appointed professor at Tokyo Tech in 2018, and also serves as the President of a Tokyo Tech venture, GX Energy ltd, since 2022.
He received the Contribution Award from the JSME in 2023 for leading the implementation of filtered containment venting systems using organic iodine removal filters in Japan.
