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 neoclassical bootstrap current, parallel electrical resistivity and radial particle and heat transport properties are examined for a reference ITER low current plasma with elevated axial safety factor, q(0), and reverse shear, q′ < 0. The results are compared with two other reference cases at full current and differing plasma profiles. In each of the cases it is found that higher Z impurities are fairly robustly expelled from the core by ion temperature gradient screening, although the screening is weaker in the high q(0) plasma because of its lower collisionality. The bootstrap current is strongly enhanced in the high q(0) case as expected. Potato orbits do not significantly modify the results.
