We aim to develop a source term evaluation method for the establishment HTGR PRA method. In this study, we developed an evaluation model corresponding to failure modes in core graphite components. In addition, we evaluate a source term for the accident sequence initiated with simultaneous ruptures of standpipes and co-axial pipings considering failure in core graphite components. The evaluation results showed the impact of graphite component failures on source term evaluation results.
