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.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The solid-state diffusion reaction between Fe and Al was studied using bulk diffusion couples in the temperature range 450°C to 600°C for annealing durations up to 240 h. The Al-rich intermetallic phase Fe2Al5 formed in the diffusion zone at all annealing temperatures. However, for diffusion couples annealed at and above 600°C, additional intermetallic phases Fe3Al, FeAl, and FeAl2 appeared in the diffusion zone. The existence of these phases at and below 640°C and the composition range of their existence were investigated, and these results provided better insight into the existing Fe-Al phase diagram. It was observed that Fe2Al5 is the dominant phase in the diffusion zone, and the formation of this phase was rationalized based on the modified effective heat of formation model. Both kinetic and diffusion parameters were evaluated for Fe2Al5, and the activation energy for interdiffusion of this phase was found to be 146.8 kJ/mol; these results were compared with previously published work.
