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.

Some recent advances in the knowledge base with respect to the ability to calculate fission product transport behavior in the reactor coolant system (RCS) and the containment for light water reactor severe accident conditions are discussed. Only minor advances are noted with respect to aerosol behavior. These include improvement in the understanding and modeling of impaction behavior, homogeneous and heterogeneous nucleation, vapor/aerosol interactions, hygroscopic behavior of aerosols, and decomposition of CsI in the presence of hydrogen flames. The focus is the influence of chemical phenomena on the behavior of fission product iodine. A review is given of new work on the chemical forms released from the RCS as they are affected by gas-phase chemical kinetics, reactions with surfaces, the presence of boric acid, and revaporization from surfaces. Also reviewed is recent work on hydrolysis and radiolysis reactions in water pools in containments to determine the potential for revolatilizing iodine species back into the containment atmosphere.
