Lithium precoating retains less fuel than powder injection in fusion study
The US Department of Energy highlighted research on deuterium retention in the DIII-D tokamak on 15 October. Samples precoated with lithium retained less fuel than samples exposed to lithium-powder injection during operation.

The nine-institution study also points to the importance of avoiding lithium buildup in cold wall regions. The findings come from a 2025 Nuclear Materials and Energy paper, rather than a new commercial reactor result. Researchers plan further work on what happens when lithium and fuel deposits melt.
