Keeping Waste Where It Belongs: Grain Size Explains How Spent Nuclear Fuel Enters the Environment (IMAGE)
Caption
Electron micrographs show neptunium dioxide grain size increases with increasing temperature. Processing the material at higher temperature increases its grain size and reduces its movement into the environment.
