Fig. 4: Variations in size and shape of noble metal phase particles.
From: Distribution of metallic fission-product particles in the cladding liner of spent nuclear fuel

(a) SEM-BSE image of noble metal phase particles in the cladding liner. (b) A slice removed from the cross-section using a FIB-SEM. A large distribution in size and shape of the noble metal phase particles is observed. The uranium “cloud” persists with the side-view.
