Fig. 3: Noble metal phase particles and uranium in the Zr liner.
From: Distribution of metallic fission-product particles in the cladding liner of spent nuclear fuel
Images of noble metal phase particles surrounded by uranium “cloud” (higher (red—upper-right and green—lower-right) and lower (yellow) concentrations of U for the images on right) with trail back to the fuel/cladding interface. A few smaller metallic particles are also visible especially along the trail of uranium. Lower two panels reused from Schwantes, Jon M., et al. A new non-diffusional gas bubble production route in used nuclear fuel: implications for fission gas release, cladding corrosion, and next generation fuel design.
