Fig. 5: Noble metal phase particles within the Zr liner.
From: Distribution of metallic fission-product particles in the cladding liner of spent nuclear fuel
(a) STEM BF and (b) STEM HAADF images of the altered Zr oxide region nearest the UO2 fuel (left side of image) with particle morphology variation evident. (c) Average particle diameter and void number density as a function of depth into the Zr oxide from the UO2 fuel. (d) Particle volume density as a function of particle diameter for depths between 0 and 6 µm depths from the fuel.
