Fusion is the process that powers the sun and stars. When two sufficiently light atomic nuclei combine to form a heavier nucleus, large amounts of energy are released. Scientists are working to harness this process on Earth as a new way to generate electricity, but making fusion work as a practical energy source is one of the toughest engineering challenges of our time. Argonne is addressing this challenge by combining advanced materials research, hands-on experiments, and powerful computer modeling.
Argonne’s experts are:
- Using advanced simulations and artificial intelligence (AI) to improve fusion reactor designs and plasma control
- Developing and testing materials that can withstand the extreme conditions inside a fusion reactor
- Applying decades of experience from fission energy to speed up fusion energy progress
In the lab for example, Argonne researchers use liquid metals and molten salts to study heat transfer and corrosion. They work to create strong, heat-resistant parts with 3D printing and test how candidate materials hold up under intense radiation. These efforts help ensure that future fusion reactors will be safe, efficient, and long-lasting.
Argonne works closely with industry, other national labs, and international partners. By scaling up research and development with national laboratory infrastructure and sharing expertise, Argonne supports the rapid growth of fusion research and industry.
Fusion energy has the potential to change the world by providing an abundant energy source. The work at Argonne is helping make that future possible.
