N2 - It has been anticipated and recently observed that axial cracks can occur at keyway corners of graphite bricks in the UK Advanced Gas-cooled Reactors (AGR). The crack initiation is triggered by internal stress reversal during reactor operation and may potentially lead to brick more cracks through a mechanism known as Prompt Secondary Cracking (PSC). To assess the likelihood of this occurring, a method for modelling dynamic fracture, known as eXtended Finite Element Method with cohesive elements (XCZM), is used to analyse whole 3D component fragmentation. Within this work, XCZM is used to model primary crack interactions with a methane hole and secondary crack profiles in a 3D brick slice under external hoop stress loading.
