Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

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.

This study evaluates heat transfer characteristics of a sub-channels-inserted (SCI) porous heat removal device for divertor cooling. It is clarified that increasing the total volume of the sub-channels strongly contributes to the enhancement of phase-change of coolant as well as the vapor discharge. A high heat flux of approximately 25 MW/m2 is removed at a wall superheat less than 70 K by increasing the number of the sub-channels installed under low flow rate conditions. The results also suggest that the SCI porous heat removal device could be applicable for the divertor cooling by optimizing the sub-channel design. Furthermore, especially for an enlarged heating area, optimizing the location of the sub-channel inlet, that is the interval of each sub-channel inlet, could be essential in order to smoothly discharge the generated vapor outside the porous medium.
