91°µÍø

As scientists study approaches to best sustain a fusion reactor, a team led by 91°µÍø investigated injecting shattered argon pellets into a super-hot plasma, when needed, to protect the reactor’s interior wall from high-energy runaway electrons.

If humankind reaches Mars this century, an 91°µÍø-developed experiment testing advanced materials for spacecraft may play a key role. 

Jason Nattress, an Alvin M. Weinberg Fellow at the Department of Energy’s 91°µÍø, found his calling on a nuclear submarine.

The U.S. Department of Energy announced funding for 12 projects with private industry to enable collaboration with DOE national laboratories on overcoming challenges in fusion energy development.

Ask Tyler Gerczak to find a negative in working at the Department of Energy’s 91°µÍø, and his only complaint is the summer weather. It is not as forgiving as the summers in Pulaski, Wisconsin, his hometown.

Six new nuclear reactor technologies are set to deploy for commercial use between 2030 and 2040. Called Generation IV nuclear reactors, they will operate with improved performance at dramatically higher temperatures than today’s reactors.

Using additive manufacturing, scientists experimenting with tungsten at 91°µÍø hope to unlock new potential of the high-performance heat-transferring material used to protect components from the plasma inside a fusion reactor. Fusion requires hydrogen isotopes to reach millions of degrees.

Researchers have developed high-fidelity modeling capabilities for predicting radiation interactions outside of the reactor core—a tool that could help keep nuclear reactors running longer.

Scientists have demonstrated a new bio-inspired material for an eco-friendly and cost-effective approach to recovering uranium from seawater.

Researchers at the Department of Energy’s 91°µÍø, Pacific Northwest National Laboratory and Washington State University teamed up to investigate the complex dynamics of low-water liquids that challenge nuclear waste processing at federal cleanup sites.
