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.

Prior to construction, the modular steam generator of the French 250-MW(e) fast breeder demonstration plant (Phenix) was submitted to a number of tests carried out on scale-one module mockups. The Phenix steam generator consists of seven tube coil-shaped modules operated as countercurrent sodium-to-water (or steam) heat exchangers. We report on the experimental verification of the accuracy of the procedures and models utilized to predict the steady-state heat transfer, the pressure losses, and the static stability of a 15-MW(th) mockup comprised of an economizer-evaporator, a superheater, and a reheater tested for 8000 h on the 5-MW(th) CEA facility at Grand Quevilly, and a 45-MW(th) mock-up comprised of three economizer-evaporators, three superheaters, and three reheaters tested 6200 h at Les Renardières on the 45-MW(th) EDF facility.
