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.

The poloidal field (PF) power supply is an important subsystem of the EAST (Experimental Advanced Superconducting Tokamak as the device status detection and protection are essential. The PF power supply monitor system is based on the Experimental Physics and Industrial Control System and the human machine interface is the Control System Studio (CSS). The alarm is a plugin of CSS, used to help operators take correct action at the correct time. This technical note creates the alarm system, including server, client, Java Message Service interface, and relational database and configures the alarm attribute and sets the action for all variables that may trigger the alarm. When the alarm is triggered, the system goes into fault mode, the alarm server sends mail or pops up a window automatically to prompt operators, and some actions may be executed automatically to protect the device. Then operators solve the fault according to the guidance and the system returns to normal, realizing device status monitoring and protection in real time. The EAST experiment shows the alarm system has better function and stable performance.
