Abstract

By using the finite element method it has been possible to simulate irradiation-induced property changes, namely dimensional and Young's modulus changes, from which the probable microstructural mechanisms have been identified. In the finite element models, both property changes were shown to be dependent upon the filler particle dimensional changes and the accommodation porosity. However, these need to be corroborated through the examination of actual specimens. Further work is also required to adapt the procedure to other graphites, reactor conditions, and material properties.
