Deskripsi
Chromia is an important additive used in uranium dioxide fuel fabrication, but its incorporation mechanism is still not fully understood. Here, the authors use X-ray absorption spectroscopy, including both near edge and extended fine structure regions, to resolve the local structure and valence state of chromium, as divalent, in uranium dioxide.
