Fig. 10

The impact of initial grain on the fission gas behavior in a 20 μm × 20 μm 2D polycrystal of UO2 at 1800 K with clustering and re-solution. The evolution of the grain structure and fission gas concentration over time are shown for the ten, twenty, and thirty grain cases in (a), (b), and (c), respectively. The four images correspond to t = 0, 336, 897, and 1389 days, from left to right. The evolution of the intergranular bubble fraction over time for the three cases is shown in (d). The fraction of Xe found within the grains over time for the three cases is shown in (e)
