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.

For reducing the liquid metal MHD pressure drop of the first wall cooling, a NaK experimental study was made on the effects of the electrical insulation of a rectangular duct. Three inner surfaces of a 2.1 mm thick 304-SS rectangular duct of 20.5 mm × 45.5 mm inner cross-section was coated by 1.3 mm thick FRP plates, remaining one of the 45.5 mm wide faces uninsulated to simulate the plasma facing first wall. The magnetic field was mainly applied in parallel to the uninsulated face. The results are summarized as follows. (1) The MHD pressure drop gradient is proportional to the mean flow velocity U and also to the magnetic flux density B. (2) It is about 2.3 times higher than the value predicted by Shercliff's theory for a completely insulated rectangular duct. (3) It is largely reduced, for the same velocity, down to 7.7% at B= 1.0 T and 5.1% at B= 1.5 T in comparison with the uninsulated duct. These results are encouraging for applying to fusion power reactors.
