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.

Linked neutronics and hydrodynamics calculations have been performed for X-1 targets using the radiation hydrodynamics computer code BUCKY and the neutronics code ONEDANT. Target neutronics calculations were performed taking into account the varying configuration during the burn as well as the distributed material densities and fusion neutron source profile. The energy spectrum of neutrons emitted from the target varies during the bum with a softer spectrum produced in early time intervals. Neutrons emitted from the target carry 69.22% of the fusion energy with 28.3% carried by the x-rays and debris. A small fraction of 0.03% is carried by gamma photons and 2.45% is lost in endoergic reactions. Full coupling of the neutronics and hydrodynamics calculations is essential for making consistent predictions of the partitioning of the target energy between x-rays, ion debris, neutrons, and gamma photons and an accurate estimate of the net target yield by accurately accounting for the endoergic energy losses and energy deposited by neutrons.
