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.

Elemental compositional analysis was carried out on various portions (edges to center) of the film on the ADITYA tokamak window using X-ray diffraction, energy-dispersive X-ray analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy. Optical transmission studies were carried out at various points along the length and breadth of the film. An automated tabletop setup was developed for cleaning the coating by back-side etching using an Nd:yttrium aluminum garnet laser operated at its second and third harmonics. Various experimental parameters were optimized so as to restore maximum transmission for the window. It was observed that a wavelength of 355 nm at an energy density of 1275 mJ/cm2 and at a repetition rate of 10 Hz was found to be best suited for this application. It was possible to restore the transmission of the coated portion to the transmission level of bare window portions using this setup.
