Figure 1. Example of a computational cell (IMAGE) Moscow Institute of Physics and Technology Caption A crystal lattice of uranium dioxide (grey atoms are uranium, red atoms - oxygen) containing a bubble of xenon (yellow atoms). Uranium atoms displaced to inter-nodal positions are shown in black. Such a cluster of interstitial nodes greatly accelerates bubble diffusion.
