The aim of this study is to clarify the behavior of helium precipitated in UO. The micro-structure of UO matrix deformed by helium infusion was examined by FE-SEM and FE-TEM. It was deduced that the shape of the negative crystal is determined by the balance between the surface energy of the lattice plane and the inner pressure of helium.
