In this paper, crack propagation in Advanced Gas-cooled Reactor (AGR) graphite bricks with\udageing properties is studied using the eXtended Finite Element Method (X-FEM). A parametric study for crack\udpropagation, including the influence of different initial crack shapes and propagation criteria, is conducted. The\udresults obtained in the benchmark study show that the crack paths from X-FEM are similar to the experimental\udones. The accuracy of the strain energy release rate computation in a heterogeneous material is also evaluated\udusing a finite difference approach. Planar and non-planar 3D crack growth simulations are presented to\uddemonstrate the robustness and the versatility of the method utilized. Finally, this work contributes to the better\udunderstanding of crack propagation behaviour in AGR graphite bricks and so contributes to the extension of\udthe AGR plants’ lifetimes in the UK by reducing uncertainties
